Infrared works by using infrared radiation, which means cameras can ‘see’ movement and people in the dark. In contrast, thermal cameras incorporate additional features to detect infrared and convert it into a thermal image.

In short, any thermal vision camera you buy will be an infrared product, but some more basic infrared cameras aren’t advanced enough to capture thermal footage, which means the right options will depend on your risks and budget.

Infrared vs Thermal Cameras: Key Takeaways

• Infrared CCTV cameras are highly effective, cost-efficient, and widely available devices that provide high-resolution black-and-white images in low-light conditions.
• Thermal imaging cameras are more sophisticated and can see in total darkness, fog and smoke, creating colour-coded footage and highlighting heat signatures.
• Each device has numerous applications, with infrared cameras often used for overnight surveillance and thermal cameras designed for higher-risk settings where security systems must operate without visible light.

How Is Infrared CCTV Different From Thermal Imaging CCTV?

Infrared (IR) cameras use reflected infrared light to distinguish features and details when there is little natural or artificial light, whereas thermal cameras use thermal radiation and function even if there is absolutely no light at all.

Even basic night vision models can detect humans in low-light conditions and distinguish between people and wildlife, but the right options will depend on the setting and the reason for the night vision cameras. [1]

A summary of the main contrasts is below:

What Are the Main Applications for Infrared Surveillance Cameras?

Infrared cameras are primarily used at sites that require security monitoring of high-risk entrances or zones in low-light conditions. The image quality and detail in captures enable managers to detect unknown individuals or unverified vehicles.

High-resolution night vision cameras are also used in various settings, including outdoor applications, and can be integrated with other security solutions, including professional CCTV monitoring. [2]

Infrared Cameras for Security Threat Detection

CCTV systems equipped with infrared can be used in almost any business or environment where security systems need to improve response times and ensure personnel have a fast way to detect and verify threats.

Fitted within multiple types of surveillance units, including dome cameras, infrared vision is accurate enough to capture facial features and objects, with the option to use AI-enabled analytics to automate responses and stand down false positives.

Car Park and Construction Site Controls

Infrared cameras can detect vehicle registration numbers and cross-check them against approved databases, or track suspicious or unrecognised vehicles, so guards can intervene if necessary.

For car parks, loading bays and logistics and transport hubs, infrared cameras are preferred because the detail within captures surpasses that available from thermal cameras.

When Are Thermal CCTV Cameras Most Often Used?

The advantage of thermal cameras is that they are suited to areas with no natural light, frequent smoke, mist or fog, or trees and foliage that render infrared cameras redundant, including perimeter monitoring systems that use PIR sensors.

Thermal imaging can, for example, detect even small or distant heat signatures that indicate a person is trying to climb a fence or crawl over a perimeter line, even in storage spaces without lighting.

Industrial Applications of Thermal Cameras

The ability to detect heat signatures isn’t just relevant to security; thermal cameras are routinely used in industrial sectors where overheating risks can pose serious threats to health and safety.

While thermal cameras must be well maintained to provide preemptive alerts when machinery approaches an unacceptable temperature or shows signs of electrical faults, they can help prevent outages and accidents before they occur.

Discreet Overnight Security Monitoring

In some cases, businesses want visible cameras as a deterrent, but there are also situations where surveillance needs to be discreet or where operators must be mindful of the risk of breaching privacy regulations.

If security cameras aren’t permitted or appropriate, or there are concerns about collecting personal data, thermal imaging cameras can be ideal, detecting when a person is present but without collecting identifiable features.

How Can Businesses Choose Between Infrared vs Thermal Cameras?

Both of these night vision cameras can be beneficial, and the key is to think about what security or operational risks you need to prevent, and what your priorities are – whether immediate notification of movement on your site overnight, or highly detailed captures.

Clearway, says, ‘There has never been as much choice when it comes to proactive security and risk mitigation, but we’d never recommend one system over another for every site or premises.”

Generally, thermal cameras are a go-to for perimeter protection and rapid intrusion alerts, whereas infrared cameras are a better option if you need accurate, high-quality footage to help responders evaluate the appropriate response.’

Frequently Asked Questions

What Are the Drawbacks of Infrared Security Cameras?

Infrared cameras are often very effective, but they can be obscured by smoke, fog, and mist, and they can’t pass through water or glass, so you’ll need to consider where cameras are positioned and where potential breaches might occur.

Can a Thermal Camera Detect Infrared Radiation?

Yes, thermal cameras can detect infrared, but they can also detect heat signatures from machinery, humans, and wildlife.

Legislation under the Data Protection Act 2018 and the UK GDPR [1] applies to CCTV in business sites, residential homes, and public spaces, and there are minimum requirements, such as providing contact details or the name of the business.

Let’s work through the CCTV signage rules, how to ensure you’re compliant, and best-practice advice for installing notices that tick all the boxes.

GDPR Compliant CCTV Signage: Key Takeaways

• All CCTV systems must comply with UK laws and regulations, including the requirement for signage that informs people that recording is taking place, by whom, and why.
• CCTV cameras used solely within a home aren’t subject to as many strict rules, but as a minimum, those used in workplaces or public access areas must have clear signage at all entry points.
• Businesses unsure whether their CCTV signage is adequate can review the official guidance on the Information Commissioner’s Office (ICO) website. [2]

Balancing the Benefits of CCTV With Regulations

CCTV has long been used as a way to deter crime and supervise buildings, but surveillance laws will almost always apply, covering what you can and can’t use CCTV for, and how to ensure your cameras are legal.

Alongside deterring trespassers and reducing break-in risks, CCTV can enhance productivity and the efficiency of work teams on construction projects. [3] However, it must be accompanied by clear signs explaining why the recording is in place.

The table below shares a quick recap of the main CCTV signage rules:

Do Businesses Need Signage Immediately When Installing a New CCTV System?

Yes, CCTV shouldn’t be in operation without the right signage, and that applies just as much to temporary wireless CCTV systems as to permanent, fixed surveillance used in offices and workplaces.

‘It’s usually far better to talk with staff and visitors about a new CCTV system before it’s installed, because this ensures there aren’t misconceptions about what recording is there for, or who will be able to access it.’

Surveillance is a great way to improve safety and reduce risks, but signage rules are in place to protect individuals’ privacy rights, which is why we’d recommend a risk assessment and consultation before simply installing cameras and erecting signs without warning.

Staff who are advised of a plan to install CCTV can share feedback, ask questions, and, in many cases, will be reassured when they’re fully informed and have the peace of mind that a professional alarm response team will keep them safe.’

Key Locations Where CCTV Signs Should Be Installed

Entrances to the Monitored Area

Signs should be positioned at all main entry points to the space covered by CCTV.

Examples:

• Building entrances
• Gates to private premises
• Access points to construction sites
• Car park entrances

This ensures visitors see the notice before they enter the surveillance zone.

Reception Areas and Public Access Points

In commercial or public-facing buildings, signage should be visible in:

• Reception areas
• Lobbies
• Customer waiting areas
• Retail entrances

These locations reinforce that CCTV monitoring is in place.

Car Parks and External Areas

If cameras monitor external spaces, signs should be placed around the perimeter or entry routes.

Typical locations include:

• Car park entrances
• Delivery bays
• Service roads
• Yard access points

Inside Buildings Where CCTV Is Operating

If CCTV operates inside a building, signage should also appear within the monitored space, especially in:

• Corridors
• Warehouses
• Shared office areas
• Hotel hallways
• Industrial facilities

Construction Sites and Temporary Sites

For construction or temporary security setups, signs should be placed at:

• Site fencing
• Temporary gates
• Site offices
• Welfare areas

This is particularly important when using temporary CCTV towers or mobile monitoring units, as people entering the site must be aware that surveillance is active.

Where CCTV Signs Are Not Usually Required

Signage is generally not required in purely domestic situations where CCTV only covers private property.

However, if home CCTV captures public areas or neighbouring property, the homeowner may still need to follow data protection principles.

Practical Rule to Follow

A good rule used by security professionals:

If a person could be recorded by CCTV, they should be able to see a sign informing them first.

How Can Organisations Ensure They’re Complying With CCTV Signage Rules?

The best way to check that your signage is compliant is to speak with an independent security expert, to organise CCTV installations with expert advice, or to refer to online resources like the government’s Code of Practice. [4]

While the latter isn’t mandatory, it provides guidelines on how businesses can use CCTV cameras while remaining within all the rules.

Signs are, however, required to ensure CCTV is legal. They can both deter intruders by warning them of the presence of CCTV and ensure anyone recorded knows this and can exercise their rights, such as requesting all the information held about them.

What Is the Link Between GDPR and CCTV Signs?

GDPR is a set of regulations that dictate what businesses must do to protect the rights of data subjects – or anyone captured by your CCTV system. Rules include:

• Making sure CCTV cameras aren’t recording anyone outside of your premises or on someone else’s private property.
• Appointing someone in your organisation with responsibility for your CCTV, registering with the ICO and creating policies that say who can access images, and when information can be shared, such as when requested by the police.
• Creating a Data Protection Impact Assessment (DPIA) that examines how CCTV is used and how the business can mitigate potential harms or issues.

Organisations also need to ensure that all personal data is processed only in accordance with their policies, that data is managed fairly, and that information isn’t kept for longer than necessary.

Data must be protected from unauthorised access and used or viewed only by individuals approved to manage CCTV footage.

How Can My CCTV Installer Help With Signage?

Experienced security specialists can advise on all aspects of installing CCTV, from choosing the right cameras and systems to ensuring you’re covering all blind spots and complying with GDPR and data protection requirements.

This can include advice on where and how to install signage to ensure anyone being recorded is aware of this before entering the area under surveillance, designing signs that include all essential information, and checking that they are visible and clear.

Frequently Asked Questions

Is Signage Always Mandatory for Premises With CCTV?

Yes, because GDPR requires you to tell people that you have a live CCTV system in place, with signs in a place where they’ll be easily seen.

What Needs to Be Shown on CCTV Signage?

You’ll need to state that recording is taking place, provide a reason (e.g., for security purposes), and include the name of the business so anyone recorded knows who the CCTV cameras belong to.

PoE cameras are a variant of IP cameras, offering the benefits of high-resolution capture, remote access to feeds, and internet connectivity without the additional cabling or wiring requirements that can make alternatives more expensive.

This guide explains how PoE cameras work, but as always, it’s worth discussing your requirements with a security surveillance professional to ensure you’re compliant with all relevant CCTV rules and only use PoE cameras where they meet data security regulations.

POE Cameras Explained: Key Takeaways

• PoE security cameras use a single cable that provides power and communications, eliminating the need for multiple wires and enabling connection to PoE switches and cloud solutions for remote access to footage.
• The main benefits relate to the flexibility of where PoE cameras can be installed and to their costs, allowing businesses to install these devices in hard-to-access positions.
• Compared with Wi-Fi-reliant cameras, PoE cameras are more dependable, with a hardwired connection that is well-suited to settings where continuous recording and surveillance are vital for security.

What Are PoE Surveillance Cameras?

A PoE (Power over Ethernet) camera is an IP-based security camera that receives both power and data transmission through a single Ethernet cable (Cat5 or Cat6)

PoE cameras provide video-based security using a single Ethernet cable, making them more convenient and cost-effective than alternatives that require a separate power source and communication cable.

To reduce installation and maintenance costs and issues, PoE cameras transmit footage either to Network Video Recorders (NVRs) or to cloud-based communication services.

Their simplicity has made PoE cameras highly sought after, with this segment of the CCTV surveillance market growing 10.2% year on year and projected to be worth over £22 billion globally over the next five years. [1]

Clearway advises that ‘PoE cameras offer a great balance of cost-efficiency and easy installation, especially for sites where unreliable Wi-Fi or limited access to mains power makes other types of IP cameras unviable or prohibitively expensive.’

What Is the Difference Between a PoE and an IP Camera?

PoE cameras are similar to IP cameras, but only PoE cameras can transmit video and power over a single Ethernet cable, whereas IP cameras rely on the internet.

That doesn’t, though, mean that there are limitations on the types of CCTV cameras you can install that are configured with Ethernet connections:

• Bullet PoE cameras can cover longer distances and feature low-light capabilities that ensure they capture events and activities even in low ambient light.
• Dome PoE cameras offer wider fields of view and are often used in retail, office, and storage settings.
• PoE cameras with PTZ capabilities are more versatile, allowing responders to adjust the camera’s angle or direction to zoom in to determine whether an alert requires an urgent response.

Businesses can also choose PoE cameras with multiple sensors, which extend the area under surveillance and incorporate extra image sensors to remove blind spots.

What Is the Benefit of Installing a PoE Camera?

The biggest advantage of a PoE camera is its simplicity: fewer components and less technical know-how are required than for an IP camera system, while offering similar functionality.

What Are the Most Common Applications for PoE Cameras?

PoE cameras are used in commercial, industrial, and residential settings to monitor movement and activities indoors and outdoors, with frequent use in office spaces, warehouses, and educational facilities.

• Offices use PoE cameras for quick, easy installation and low-cost maintenance, helping protect workplaces with remote access to real-time footage.
• Warehouses and depots install PoE cameras to simplify installation, using 4K systems equipped with features such as night vision and video analytics to protect against thefts, break-ins, and safety breaches.
• Schools and colleges choose PoE cameras to cover complex site layouts, with weatherproof outdoor units fitted along perimeters to deter vandals and intruders.

This is just a summary of the uses of PoE cameras, which are also prevalent in retail and hospitality, where the ability to detect unusual movement or suspicious patterns can be vital for keeping personnel and site users safe.

There are also niche and specialised uses of PoE surveillance systems, including public space analytics to assess the suitability of pavements and walking paths in outdoor environments for people with disabilities. [2]

Frequently Asked Questions

Are There Drawbacks to Installing PoE Surveillance Cameras?

Potentially, yes, which is why it’s always advisable to consult an experienced professional, as there’s no single CCTV camera type that suits everyone.

Depending on your site layout, the distances between the spots where you’d like to install cameras may require extra resources to run Ethernet cables, though extenders can resolve this.

Why Is a PoE Camera Better Than a Wi-Fi Connected Surveillance Device?

There’s no single solution for every business or site, but generally, a PoE camera outperforms a Wi-Fi camera if you need assurance that your cameras are stable and won’t be vulnerable during outages.

Wi-Fi cameras are more flexible and very easy to install if fitting or laying cables would pose a problem, but they’re also reliant on the strength and continuity of your Wi-Fi connection.

Do PoE Security Cameras Only Provide On-Site Access to Footage?

No, despite misconceptions, PoE cameras are advanced and adaptable. Each unit records and encodes footage on the device itself and transmits data over an Ethernet cable so you can access it on any device you’re using.

This means business owners and site managers can tap into live feeds or alerts through both secure closed networks and via the internet, depending on their requirements.

Installing turret cameras is often ideal for businesses and settings that don’t want a bullet camera, which can seem a little intrusive, but need a cost-effective surveillance system that offers more reliable infrared coverage than dome cameras.

The drawback is that, unlike dome cameras, a turret camera lacks a protective cover, which makes it more vulnerable to vandalism. It’s worth speaking to an experienced security professional to ensure you pick the right CCTV for your premises.

Turret Cameras: Key Takeaways

• Turret cameras can be installed indoors and outdoors, and their ability to rotate means each device offers improved coverage.
• Devices can monitor activities and movement at close range and over longer distances and are visible enough to deter crime.
• One of the big advantages of turret cameras is their enhanced low-light capabilities. The lack of a dome cover improves infrared captures, but it can make the camera more exposed to damage.

What Are the Key Features of Turret Cameras?

The primary advantage of turret cameras over alternatives is their 360-degree rotation, achieved with a ball-and-socket design that allows the camera to move freely and cover a wider area.

Other functions and capabilities are as follows:

When Would Turret Cameras Be the Best Surveillance Option?

Typically, turret cameras are ideal when bullet cameras are a little too aggressive or intimidating, or when there have been previous issues with debris and insects affecting their performance.

They’re also often compared with dome cameras, each with its own pros and cons, and are selected when infrared reflections can make dome cameras less effective.

Clearway advises that, ‘CCTV is known to have a positive effect on crime prevention, with premises with cameras experiencing 14% less crime than those without – but choosing the right types of CCTV devices is important. [1]

Our advice is to start with a risk assessment or audit of your current security devices, which helps us spot vulnerabilities, issues or gaps in coverage that influence the recommendations we make.’

How Do Dome and Turret Cameras Compare?

It’s common to choose between dome and turret security cameras. While both are effective, turret cameras are often better suited for overnight security, while dome cameras are best for settings where surveillance needs to be discreet.

We’ve put together a brief comparison below to highlight the differences that might affect your decision-making.

What Are the Advantages of Turret Cameras?

Turret cameras offer versatility, with the ball-and-socket joint allowing movement around the ball to cover different areas or zoom in and out as needed. The other positives of picking a turret camera for an office or business include:

• Modern camera casings, which are less conspicuous than bullet cameras, but still visible enough to deter.
• Improved night vision, with infrared LEDs providing reliable surveillance in low light or complete darkness.
• Options to integrate turret cameras with professional alarm response monitoring.

The latter is important because over 88% of CCTV systems in the UK are supported by a monitoring service, compared to just over 58% in the US, which is thought to be why visible cameras here generate greater security improvements. [2]

Installing a CCTV surveillance system is a proactive way to deter intruders, but it won’t necessarily eliminate all risks.

Having a professional response service monitor alerts and activate the appropriate protocol is the best way to ensure intrusion attempts and other incidents are de-escalated as quickly as possible.

Are There Downsides to Installing Turret Cameras?

There are thousands of potential CCTV systems to choose from, and it’s worth knowing the drawbacks, such as limited pan and tilt ranges that affect some turret cameras compared to alternatives.

Some businesses also find that the visibility of a turret camera is a drawback if they want a discreet CCTV system. However, it’s also vital that any setting understands the CCTV rules, because covert and concealed CCTV cameras are rarely compliant or advisable.

Turret cameras typically need to be installed relatively low down compared to other types of CCTV, which may mean the positioning of your cameras or the areas you need to protect will impact your choices – and, as with any CCTV device, there are both basic, low-cost models and sophisticated solutions that command a higher budget.

Frequently Asked Questions

How Do Turret Cameras Work?

Turret security cameras are oval-shaped devices mounted on ceilings or walls, with a ball-and-socket mechanism that allows the camera to spin in any direction, covering more angles than a fixed camera.

When Is a Turret Camera Not the Best Option?

If you want a highly visible, robust deterrent or a discreet, low-profile CCTV camera as your top priority, we’d usually recommend a bullet or dome camera rather than a turret camera.

CCTV towers are in strong demand from construction sites, events, high-risk compounds, transport providers and energy plants, where conventional mains-powered and wall-mounted cameras would be unviable, and managers need to cover wider areas simultaneously.

This guide summarises the features and functionality of varied CCTV surveillance towers to illustrate the contrasts.

Different Types of CCTV Towers: Key Takeaways

• CCTV towers range from mains-powered devices to autonomous, solar-powered models that operate independently of the grid and provide an ideal solution for remote, isolated, or large-scale sites.
• Some types of CCTV Towers cameras are specifically designed for niche environments, such as traffic management systems that monitor vehicle volumes and speeds to improve road safety.
• Picking the right CCTV tower will depend on the nature and layout of the site, access to a power supply, the duration of the risks you need to control, and your security concerns.

What are the different types of CCTV Towers?

There are several types of CCTV towers, each designed for different environments, risk levels and deployment needs. The right option depends on whether you need rapid deployment, long-term coverage, power independence or advanced analytics.

Type 1: Static CCTV Towers

These are fixed-position towers installed for medium to long-term monitoring. They are typically connected to mains power and broadband or fibre, making them ideal for sites with existing infrastructure such as industrial estates, car parks and logistics hubs.

Type 2: Mobile CCTV Towers

Mobile towers are designed to be moved easily between locations. They are commonly used on construction sites, temporary compounds and vacant land where security needs change over time. Most are trailer-mounted or skid-based for fast relocation.

Type 3: ANPR CCTV Towers

These towers are equipped with specialist cameras designed to capture and read vehicle number plates, day and night. They are commonly used at site entrances, access roads and car parks for vehicle monitoring and access control.

Type 4: AI-Enabled CCTV Towers

AI-enabled towers use intelligent analytics to detect people, vehicles, intrusion events and unusual behaviour. This reduces false alarms and enables proactive responses rather than relying on manual monitoring alone.

In reality, most modern CCTV towers are not limited to just one type. The features described above are often integrated into a single, multi-purpose tower, giving sites flexibility without needing different systems for different risks.

A good example of this is the Clearway InView CCTV Tower.

Rather than choosing between mobile, solar, AI or ANPR towers, many solutions combine these capabilities into one platform:

Mobile and rapid deployment – The tower can be delivered, installed and operational quickly, making it suitable for construction sites, vacant land and temporary projects.

Solar-powered with battery backup – Integrated solar panels and batteries allow the tower to operate off-grid, removing the need for mains power and enabling deployment in remote locations.

AI-enabled analytics – Intelligent detection distinguishes between people, vehicles and irrelevant movement, reducing false alarms and enabling faster, more accurate responses.

ANPR capability – Specialist cameras can be added to capture and read number plates at entrances and access routes, day and night, supporting access control and vehicle monitoring.

Remote monitoring and live response – All data is transmitted securely for live monitoring, audio challenge and escalation when genuine threats are detected.

How Do the Clearway CCTV Towers Compare?

We’ve compared our inView CCTV tower, designed to secure high-risk environments, with the InView Highway Technology Tower, created for road safety applications, to illustrate some of the primary differences.

InView cameras are often considered a gold standard, with fully weatherproof casings, mobile network connectivity, monitoring through Clearway’s in-house NSI Gold Cat II-accredited Alarm Receiving Centre (ARC), and integral smart infrared LEDs for overnight captures.

Why Does My Choice of CCTV Tower Matter?

Each site or premise will have a distinct set of challenges or problems, and needs to adapt its security approach accordingly, since a set of alarms or CCTV cameras that works well for one compound might leave glaring security gaps at another.

It’s also important to think through the practicalities and your requirements, which should help narrow down the options.

‘Surveillance coverage is often vital in remote and high-risk areas, and it is equally important to make informed decisions about the best CCTV towers that will provide effective, reliable protection.

Starting with a risk assessment to identify core threats, vulnerabilities and priorities is advisable, as this ensures you can select the optimal CCTV solutions to bring those risks under control.’

What Factors Will Affect the Right CCTV Tower for My Site?

The following should all be considerations when comparing solar-powered CCTV towers or deciding which units to install, including your power source and site layout:

1. Access to power: CCTV towers can operate with mains electricity, solar cells, batteries, generators or a combination – so you must know what power options are available and how reliable they are.
2. Duration of security risks: In some situations, security risks are temporary, such as during construction. In others, threats are subject to change, which can influence the time period you’d need to hire a CCTV tower for.
3. Layout and site perimeters: Larger compounds and construction sites may require multiple towers or might need integrations with access controls and alarms.
4. Surveillance performance: Risks that arise primarily overnight require night vision or thermal imaging, and many sites require CCTV towers with remote viewing access.
5. Environmental aspects: Specific sectors have their own considerations regarding health and safety, regulatory compliance, and how CCTV towers need to operate – including public sector spaces, vacant properties, construction sites, railway depots, and traffic control teams.

If in doubt, it is worth scheduling an independent risk assessment with a consultant to help narrow down the options.

Where Are CCTV Towers Most Often Used?

CCTV tower installations can be used on any site where conventional or static CCTV isn’t possible or wouldn’t be effective, including construction sites with elevated theft risks and site boundaries that are difficult to control.

Research has shown that vandalism is just as costly to smaller construction sites as theft, which is why robust preventive measures are often considered mandatory in the sector. [1]

Other uses include demolition sites, vacant properties, agricultural and remote businesses or sites, compounds and corporate complexes that need 24/7 protection and solar and wind farms in isolated areas.

While these are the most prevalent applications, CCTV towers can also be used for event management and to enhance security coverage during periods of temporarily higher risk.

Frequently Asked Questions

How Effective Are CCTV Towers?

CCTV Towers are a proven deterrent and can provide extensive coverage of sites of all sizes, with a tower height of up to six metres that is impossible to overlook.

CCTV towers can be deployed quickly and installed anywhere, ensuring that any intrusion attempts, trespass or thefts will be immediately detected, the alarm sounded, and security personnel or the police notified.

Are CCTV Towers More Cost-Effective Than Traditional CCTV?

In many cases, yes, because towers can be hired for any period of time, and don’t require cabling, wiring, or trenches, since they operate on solar and battery power rather than the mains grid.

The extended coverage, reduced reliance on manual guarding, rapid notifications when suspicious activity is identified, and proactive responses to de-escalate emerging incidents can all deliver considerable cost savings.

If you’re looking to track license plates at night, you’ll need to consider infra-red capabilities. The best CCTV cameras for reading number plates at night are specialised License Plate Recognition (LPR/ANPR) cameras with infrared (IR) capabilities,

This guide shares some of the key features and capabilities you may need if you’re reliant on a CCTV system that can detect number plates overnight, depending on the application and nature of the site or facility you need to protect.

Key Takeaways

• Not all CCTV cameras can read number plates at night. You need cameras designed specifically for ANPR or low-light capture, with the right combination of sensor, lens, shutter speed and infrared performance to avoid blur and glare.
• Infrared capability is essential for night-time number plate capture. Cameras need properly tuned IR illumination to light reflective plates without causing flare or overexposure, which is a common reason plates become unreadable at night.
• Lighting and setup matter as much as the camera itself. Correct mounting height, angle, distance and controlled infrared illumination are critical for capturing clear plates, especially in complete darkness or with fast-moving vehicles.
• The best solution depends on the environment and use case. Car parks, construction sites, roads and gated entrances all require different specifications, so choosing the right camera means matching the hardware to speed, distance, lighting conditions and compliance requirements.

Why Is Number Plate Recognition an In-Demand CCTV Capability?

Number plate recognition is widely used in policing, enabling the detection of lost or stolen vehicles, tracking movements, researching vehicle routes, cross-checking alibis, and identifying possible victims or witnesses. [1]

Advancements in technology have made ANPR cameras more accessible and cost-efficient, with options to either install standalone cameras solely for the purpose of managing access controls or car parks, or with ANPR functions built into CCTV solutions.

ANPR cameras are 92% accurate in identifying whether number plates are stolen or fake, demonstrating the precision and reliability of these advanced systems. [2]

What Should I Look for in a CCTV Camera That Can Read Number Plates at Night?

When choosing a CCTV camera that can reliably read number plates at night, make sure it has the right combination of hardware and configuration to capture sharp, legible plate images in low-light or no-light conditions. Here’s what to look for:

1. Strong infrared (IR) performance – Look for cameras with powerful and well-designed IR illumination that can evenly light number plates without washing them out. Good IR range and adjustable IR help ensure clear night-time capture at the distances you need.
2. High resolution sensor – A higher-resolution sensor (e.g., 4 MP or above) gives you more detail in the image. This extra detail is critical when zooming in on plates to read characters clearly, especially at a distance.
3. Fast shutter and good low-light sensitivity – A camera with good low-light performance (low Lux rating) and the ability to use higher shutter speeds reduces motion blur from moving vehicles at night. Sensors with larger pixels and noise-reduction help too.
4. Appropriate lens and focal length – The lens determines how close and how clear the plate will appear. Choose a focal length that matches the distance between the camera and the vehicle path so number plates fill enough of the frame to be legible.
5. ANPR/ALPR support (if needed) – Some cameras and systems offer built-in Automatic Number Plate Recognition (ANPR) or work with analytics that can detect and read plates automatically. If you want automated alerts or logging, this matters.
6. Installation and alignment considerations – How and where the camera is installed—height, angle, field of view and how IR lights are aimed—can make or break number plate readability at night. Proper setup tailored to the location is as important as the camera itself.

A summary of the most important characteristics for many settings is as follows, while noting that some use cases, such as ANPR on a high-risk construction site, may require additional features.

Another aspect is to consider how number plate detection will fit within your overall security approach, because scanning a vehicle and determining whether it is authorised is just the first automated process.

Businesses may, for example, need CCTV with instant notifications to raise an alarm when an unknown vehicle approaches, require gates and bollards that can prevent unapproved vehicles from entering or leaving, or use NSI Gold Monitoring services to investigate alerts and activate the appropriate response.

What Is the Benefit of Installing CCTV That Can Read Number Plates?

Number plate detection offers significant advantages, especially for sites with a constant flow of personnel and delivery vehicles, because it means they can monitor and approve every arrival in a timely manner.

Some of the many efficiencies and security improvements available include:

• Effectively capture speeding vehicles and unauthorised vehicles – especially at night, where crime is more likely to occur
• Evidence collection in case of a road accident incident
• Reduced pressure on guards or staff to physically intercept each vehicle and check the identities of the occupants.
• Automated detection of suspicious activity for cameras with AI-enabled analytics, identifying, for example, vehicles that return repeatedly or cars that have been on site for an unusually long time.
• Access controls, where gates and bollards lift automatically for recognised vehicles without any manual intervention or time-consuming processes.
• Real-time activity monitoring, with supervisors able to trace delivery times or compare on-time consignments, and stagger deliveries to avoid bottlenecks or delays.

Thinking through the purpose of your number plate detection, how it will integrate with other security measures, and how your cameras will be used will help you select the optimal devices with the necessary night vision for 24/7 coverage.

Frequently Asked Questions

How Can CCTV cameras read number plates at night?

CCTV cameras read number plates by combining the right camera hardware, lighting and image processing to capture clear, high-contrast images of the plate, even when vehicles are moving or it is dark.

How Can CCTV Cameras Read Number Plates?

Cameras with ANPR technology can differentiate between people, vehicles and wildlife and will recognise when a vehicle is approaching to automate number plate scanning. That information is then compared to a database to check if the number plate is known and approved.

In access control systems, responses are pre-programmed, such as activating an alert when an unrecognised vehicle attempts to gain entry or logging arrival and departure times.

What Happens if a Vehicle Has an Overseas Registration Plate?

Cutting-edge ANPR cameras can scan any number plates, including those from overseas, and conduct the same cross-checking as with a UK-based registration.

Choosing CCTV for a business premises can be complex, especially if you’re not clear on the contrasts between bullet and dome cameras, aren’t sure about when and how you’d want to access your surveillance, or don’t know the rules for CCTV that apply in your sector.

This guide shares some insights, advice and suggestions as a buyer’s guide for any business considering purchasing a new CCTV system.

Commercial CCTV Options: Key Takeaways

• CCTV cameras come in various designs and casings, each with differences in terms of their field of view, zoom capabilities, night vision, and how they actively deter threats.
• Business owners may also need to consider the difference between wireless and hardwired CCTV, with the former often used within car parks, open land and compounds that can’t be protected by conventional cabled cameras.
• Conducting a full risk assessment is often advisable, as it helps clarify the threats you’re facing, when and where they occur, and how best to mitigate them.

Which CCTV cameras do I need? The 5 Criteria

It’s best to approach CCTV with 5 factors in mind:

1. Why do you need CCTV?
2. Which features do you need based on your use case
3. Where will your CCTV be located?
4. Are you replacing or upgrading your current CCTV?
5. What is your budget?

Businesses stuck on comparing commercial surveillance systems are normally advised to speak with a professional, since there are so many options, it’s easy to get it wrong.

Clearway’s commercial surveillance advisory team says, ‘We often speak with clients who know they need CCTV surveillance – but there are literally hundreds of potential cameras, designs, features and integrations that could be suitable.

The best advice is to organise a risk assessment or give us a call, but in the meantime, we’ve summarised some of the most important factors you’ll need to consider.’

5 Questions to Ask when choosing Commercial CCTV

1. The Reason for Installing CCTV

It might seem obvious that CCTV is there to deter intruders, but it’s essential you state the purpose of your surveillance to comply with workplace CCTV regulations.

You might need to monitor perimeters, prevent employee theft, safeguard inventory, or identify issues such as equipment malfunctions or non-PPE compliance, for example.

Businesses installing new CCTV systems are also advised to analyse the ICO guidance on storing and using personal data, especially when they intend to use commercial CCTV in workplaces to monitor employees. [1]

2. The Features You Need Your CCTV to Have

CCTV cameras can have numerous features, including video analytics, infrared for overnight surveillance, and remote-controlled PTZ movement. Having a checklist of what your CCTV needs to do will narrow down the options.

3. The Location of Your Planned CCTV Installation

Commercial CCTV cameras can be installed inside or out, be obvious or discreet, be erected on towers, or be fitted inside recesses – and the position of the cameras will influence the types of CCTV that are appropriate.

4. The Existing Alarms or Cameras On Site

If you already have alarms, CCTV cameras, fire detectors, and access controls, you may need a surveillance system that you can integrate with them to ensure all of your devices and surveillance systems are connected.

5. The Budget You Have to Spend

Costs are always a consideration, and if you have a maximum budget or a time constraint, they might be a major factor in your decision-making.

However, it’s also important to think about whether a low-cost basic CCTV system will be sufficient to protect you from the much higher costs of break-ins or thefts.

What Are the Main Types of Business CCTV Systems?

The table below summarises some of the most commonly used CCTV systems we install, including dome, tower-mounted and PTZ cameras.

Many of these attributes can be combined. For example, a dome camera might also have IP functionality, and a CCTV tower will often have PTZ capabilities.

You should also remember that hardwired CCTV systems can be more complex to install, but they’re a permanent security fixture once in place. Wireless cameras are usually used for the short-term, on a hire basis.

Choosing CCTV Based on Your Use Case

The best type of commercial CCTV depends on what you are protecting, how the site operates, and how the footage will be used. A system that works perfectly for a retail store may be completely unsuitable for a construction site, warehouse, or vacant property.

Below are the most important considerations when selecting CCTV for commercial use.

Wired vs Wireless CCTV Systems

Wired CCTV systems use fixed cabling for power and data transmission and are commonly deployed in permanent commercial premises.

Best suited to:

• Offices, warehouses, factories, retail parks
• Sites requiring 24/7 recording without interruption
• Environments with existing power and network infrastructure

Advantages:

• Highly stable and reliable
• Consistent image quality
• Better for multi-camera and high-resolution deployments

Limitations:

• Higher installation time and cost
• Less flexible if layouts or coverage requirements change

Wireless and Non-Wired CCTV systems transmit footage over Wi-Fi or mobile networks and may be battery or solar powered.

Best suited to:

• Temporary or rapidly changing sites
• Construction projects, events, remote locations
• Short-term or mobile security requirements

Advantages:

• Fast deployment
• Flexible camera placement
• Minimal site disruption

Limitations:

• Dependent on signal strength
• Battery management required
• Not always ideal for continuous high-traffic monitoring

IP CCTV vs Analogue CCTV

IP CCTV (Internet Protocol) is now the standard for most commercial installations.

Best for:

• Businesses requiring high-definition footage
• Remote access and cloud integration
• Advanced security features and analytics

Advantages:

• Superior image quality
• Easier scalability
• Supports intelligent analytics and automation

Considerations:

• Requires adequate network capacity
• Higher upfront cost, lower long-term limitations

Analogue CCTV is typically used where legacy systems are already in place.

Best for:

• Basic monitoring needs
• Simple upgrades without full system replacement

Considerations:

• Lower image quality
• Limited analytics and integration
• Less future-proof

For most modern commercial environments, IP CCTV offers greater long-term value.

Image Quality and Camera Resolution

Resolution directly affects how usable footage is.

Consider:

• Identification vs general monitoring
• Facial recognition requirements
• Licence plate visibility
• Distance and field of view

Higher resolution cameras are essential for evidential use, while lower resolution may be sufficient for general area coverage.

Field of View and Camera Type

Different camera styles serve different purposes:

• Fixed cameras for focused monitoring
• Dome cameras for discreet indoor coverage
• Bullet cameras for visible deterrence
• PTZ cameras for large open areas

Choosing the wrong camera type can result in blind spots or unnecessary overspend.

Lighting Conditions and Night Performance

Poor lighting is one of the most common reasons CCTV fails.

Consider:

• Low-light or no-light environments
• Infrared vs colour-at-night technology
• Glare from vehicle headlights or street lighting

Sites operating at night require cameras designed for consistent low-light performance.

Intelligent Analytics and AI Capabilities

Modern commercial CCTV increasingly uses AI-driven analytics to move from passive recording to proactive security.

Analytics can include:

• Intrusion and perimeter detection
• People and vehicle classification
• Loitering detection
• Line crossing and restricted area alerts
• Object removal or abandonment detection

Best suited to:

• Large or unmanned sites
• High-risk environments
• Businesses needing real-time alerts and intervention

Analytics reduce false alarms and manual monitoring requirements.

Monitoring, Alerts and Response

Consider how footage will be used:

• Live monitoring vs post-incident review
• On-site monitoring vs remote monitoring
• Automated alerts vs manual review

For critical environments, CCTV is often paired with monitored services to ensure incidents are acted on immediately.

Storage, Retention and Access

Storage requirements vary significantly by use case.

Key considerations:

• Local recording vs cloud storage
• Required retention period
• Ease of footage retrieval
• Data protection and GDPR compliance

Longer retention and higher resolution footage require more storage capacity.

Scalability and System Growth

Commercial CCTV should support future expansion.

Ask:

• Can additional cameras be added easily?
• Can analytics be enabled later?
• Is the system compatible with third-party platforms?

A scalable system avoids costly re-installs as the business grows.

Environmental and Durability Requirements

The physical environment matters.

Consider:

• Indoor vs outdoor use
• Weather exposure
• Dust, vibration, or vandalism risk
• Operating temperatures

Construction sites, for example, require far more rugged equipment than offices.

Compliance and Insurance Requirements

Some sectors have specific compliance needs.

Consider:

• GDPR and privacy controls
• Insurer requirements for evidence quality
• Industry-specific standards

CCTV that fails to meet these standards may not be accepted as valid evidence.

Budget vs Risk Profile

Cost should be balanced against risk, not just price.

Low-risk environments may only need basic coverage, while high-risk sites benefit from intelligent, monitored systems that prevent incidents rather than just record them.

What Is the Best CCTV System for My Business Type?

As we’ve seen, you’ll need to consider all the attributes your cameras should have, and there isn’t necessarily one type of CCTV that will be perfect for two similar businesses.

For example, one retail centre might need inobtrusive dome cameras throughout, and another might require wireless CCTV to monitor loading bays and large paid-for car parks.

Reviewing the data protection guidelines and regulations before you move forward is also time well spent, helping you stay up to date with the requirements for using CCTV sensitively and with respect for personal privacy. [2]

However, the suggestions below are based on general business characteristics and priorities.

Business 1: Hospitality, Office or Retail Businesses Wanting Discreet Surveillance

In this situation, a dome camera is likely the best option because it provides 360-degree coverage, and it’s impossible to tell where it’s pointing. This both deters thieves and avoids disconcerting genuine customers or staff.

Dome cameras also need only straightforward maintenance because the lens is protected from dust.

Business 2: Construction Sites and Developers With Outdoor Land

CCTV towers are commonly used for construction sites and in other industrial applications. Towers are easy to see, a robust deterrent, and can cover large areas, with wire-free functionality that operates independently of the national grid.

Business 3: Industrial Parks With Heightened Overnight Break-In Risks

Bullet cameras are widely used in commercial and industrial settings because they are durable, weatherproof, and can capture high-quality images from a distance.

The casing is visible and a deterrent, and infrared night vision can protect industrial sites and car parks in any light.

CCTV Towers are also great for monitoring outdoor areas, depots and car parks.

Business 4: Transit Hubs and High-Footfall Warehouses

Warehouses and logistics sites often use a variety of cameras per zone, but many use turret cameras because the ball-and-socket design allows the camera to swivel to cover every area within the perimeter or space.

CCTV Towers are also great for monitoring outdoor warehousing areas, depots and car parks.

Business 5: Interior Decorators, Developers and Property Managers

During periods when commercial units or buy-to-let premises are being refurbished, awaiting sale, or pending new tenants, running mains-powered CCTV may not be possible.

Wireless CCTV is ideal, as it can be hired for temporary periods and runs from commercial-grade batteries.

Business 6: Larger Business Sites or Compounds With Live Video Analytics

CCTV cameras with PTZ features are reliable for businesses that need to supervise larger buildings or areas.

Outdoor PTZ cameras can cover car parks, loading bays, and entrances, whereas indoor PTZ cameras can be used in warehouses and venues, with the ability to zoom in and move the camera in any direction.

How Can I Be Sure I’m Choosing the Best CCTV for My Organisation?

Security cameras can be a significant investment, and it’s advisable to speak with an independent specialist who can review the pros and cons of all the options, provide tailored recommendations, and ensure you’re delighted with the performance of your commercial CCTV.

By now, you should have a greater idea about the types of features, functions and applications of modern commercial CCTV devices – and which would prove most beneficial in securing your premises, protecting your staff and defending your assets from theft.

Frequently Asked Questions

What Should I Expect to Spend on a Commercial CCTV System?

As a very rough indication, the current average prices in the UK for a CCTV camera range from around £100 for a basic model to £3,600 and above for advanced devices, and installation can cost from as little as £350 to several thousand for very complex, extensive commercial surveillance solutions. [3]

However, it’s incredibly difficult to provide even ballpark figures because every business is different and may need different installation and wiring services, integrations with software and alerts, or rely on 24/7/365 monitoring to investigate CCTV alerts when their premises are shut.

Can I Use Simple CCTV Cameras Designed for Residential Homes at My Business?

Potentially, but it’s not advisable. Residential cameras usually have limited functionality and are meant to deter intruders by protecting a single front door or entrance path. They also tend to be less durable and will rarely comply with the terms of insurance coverage.

Commercial-grade CCTV can protect multiple entry and access points, provide weatherproof casings engineered to last for years, and integrate with other surveillance assets and alarms to keep buildings properly defended.

The post Best Commercial CCTV: Which CCTV System Is Best for Your Type of Business? appeared first on Clearway.

CCTV footage is considered personal data under data protection laws like the UK GDPR and Data Protection Act 2018, as it identifies individuals through images or voice recordings. This applies to both commercial and residential systems that capture footage of people outside private property boundaries.

The rules around CCTV primarily relate to captures where an individual is identifiable, and visual footage is subject to data protection laws as any other, when it shows a known person or might influence the way they are treated.

This guide summarises the circumstances in which CCTV is most likely to be categorised as personal data, and what that means for organisations reliant on surveillance to keep their workplaces and assets safe.

CCTV Data Protection Compliance: Key Takeaways

• Businesses that record staff, visitors or members of the public are capturing information that can constitute personal data if footage includes identifiable characteristics.
• Legal obligations mean organisations must inform all parties that recording is taking place, have policies around how data is stored and deleted, and demonstrate the justifiable reason CCTV is required.
• Failure to meet data protection rules can have serious consequences, including investigations, enforcement action, reputational damage and exposure to valid legal claims.

When Is CCTV Considered Personal Data Collection?

CCTV footage that contains information that can be directly linked to a person, such as their face, is usually treated as personal data.

There are countless scenarios in which CCTV is installed, whether to supervise staff in a workplace, to ensure vehicles can’t leave a car park without paying, or to protect against shoplifting and antisocial behaviour in shops and retail parks.

Some of the many situations in which CCTV could be regarded as the collection of personal data include:

• When footage would enable an individual or their vehicle to be identified
• CCTV that incorporates audio recording – this is rarely advisable
• Monitoring within workplaces, including in communal areas and car parks
• Recording within public or shared spaces, such as pavements

It’s a common misconception that CCTV recordings aren’t personal data because they are a very different medium than a personnel record or occupational health assessment.

However, this can be a grave error, because the management, usage, and storage of CCTV is strictly governed by regulations and legislation.’

How Can I Ensure My CCTV Is Data Protection Compliant?

The exact strategies and CCTV policies you need may depend on the positioning and purpose of your CCTV, but having the right systems and processes in place, and informing all staff of the recording you’re using, is a good starting point.

The following apply to most fixed CCTV systems used in buildings and businesses:

1. Having a justified, legally valid reason for collecting CCTV captures
2. Creating an impact assessment that sets out the effects of CCTV and how to mitigate any possible issues or concerns
3. Informing all individuals about how and where CCTV is being used, with privacy notices and signage
4. Sharing details about how employees and other individuals can exercise their rights as data subjects, such as requesting all information held about them
5. Ensuring cameras are installed with privacy in mind, excluding any areas such as bathrooms or changing spaces that are deemed private
6. Implementing sufficient security measures to avoid any unauthorised access to CCTV footage
7. Defining how long information will be held, and when and how it will be deleted

The Information Commissioner’s Office (ICO) sets out a comprehensive list of considerations and requirements for any UK business installing CCTV surveillance. [1]

Further guidance about the legalities of CCTV recording is available through the government’s Surveillance Camera Code of Practice. [2]

What Happens if a CCTV System Is Found to Breach Data Protection Rules?

Ramifications for non-compliance are substantial and include fines, investigations and legal action, depending on the severity of the data breach.

What Is the Best Way to Check CCTV Systems Are Compliant?

The advice is always to consult an experienced, independent team of CCTV specialists who understand the rules and regulations, and can offer tailored recommendations, either when installing new CCTV or auditing your existing surveillance.

Best-practice CCTV is used respectfully and with caution, ensuring businesses protect themselves against the risks of theft or vandalism without infringing on privacy entitlements.

Many organisations rely on security advisers to assist with risk assessments and impact evaluations, alongside the design, installation, and commissioning of compliant CCTV that meets their security needs, often combined with dedicated monitoring through an accredited Alarm Receiving Centre.

Frequently Asked Questions

What Do Businesses Need to Do to Protect Personal Data Collected By CCTV?

CCTV that records any identifiable information about a person can be classed as personal data, which means businesses must ensure they’ve thought about the lawful basis for their CCTV, how they’ll guarantee data security, and how to limit surveillance outside of the stated purpose.

Why Is CCTV Subject to GDPR and Data Protection Regulations?

Although many mistakenly believe that CCTV isn’t personal data, this isn’t correct. Any captures that include identifiable individuals are considered personal data, which means that data protection legislation applies.

In much the same way as an organisation has a duty to safeguard confidential digital records, it has to fulfil mandatory responsibilities regarding the use, storage, access to, and deletion of CCTV recordings.

Which UK Laws Relate to Personal Data Collection and CCTV?

The updated UK GDPR and Data Protection Act 2018 governs the use of CCTV in the UK, while ICO guidance and workplace regulations also apply depending on where cameras are installed.

The post Is CCTV Personal Data? Staying Compliant When Capturing Footage appeared first on Clearway.

While both cameras have a round-shaped design, the lens within a dome camera is protected behind a clear ‘shield’. In contrast, the flexible ball cameras in a turret can pivot and swivel, without a cover.

Each CCTV device has several applications and benefits, and the best solution is to analyse your risks and requirements, rather than picking a specific type of CCTV camera solely based on how it looks.

Comparing Dome and Turret CCTV Cameras: Key Takeaways

• Dome and turret cameras have relatively small profiles and incorporate numerous features, such as motion detection, PTZ, and infrared for overnight surveillance, but there are nuances and differences to be aware of.
• The discreet nature of a dome camera means these are most often installed in spaces like offices and shops where surveillance can’t be overt or disruptive, while turrets are seen as providing the simplest CCTV maintenance in dusty or outdoor areas.
• Each camera performs reliably and can be integrated with other security assets, and decisions may depend on the types of risk in question, the potential for tampering, and the layout of the area you need to monitor.

Are Dome and Turret CCTV Cameras the Same Thing?

It’s common to assume that two round CCTV cameras provide identical functionality and features, but this isn’t correct. Dome and turret CCTV cameras are not the same, as they differ in design, visibility, and how well they perform indoors, outdoors, and at night. Here is a summary of the most notable differences.

While every site will be different, dome cameras are ideal for public access spaces where vandalism is possible, covering large areas and providing discreet coverage. Turret cameras are well-suited for long-range surveillance and for sites with high moisture levels.

Why Does the Choice Between Dome and Turret Cameras Matter?

Any fixed CCTV system should be designed to mitigate the risks and threats relevant to your premise, and to deter or proactively pick up on suspicious activity that needs to be investigated, you need the appropriate coverage and features.

There is ample evidence that the angle, field of vision and position of CCTV cameras are key to providing effective security, which is why businesses need to understand how different types of cameras work to determine which are right for their premises. [1]

Even the highest-performance CCTV camera can fail to prevent crime if the surveillance system doesn’t have the right functionality, isn’t used correctly, or isn’t updated to respond to changes in assessed risks. [2]

Clearway’s CCTV security team says, ‘Designing and deploying surveillance systems is all about learning the most appropriate ways to mitigate risks and create a safe, secure environment, whether an office, school, construction site, retail park or public town centre.

We always recommend that any organisation comparing CCTV cameras consult an experienced professional, because picking a system that leaves blind spots, doesn’t work properly in heavy rain, or isn’t visible enough to form a deterrent can mean additional cost and unresolved risk.’

What Are the Characteristics and Features of Dome Cameras?

Dome cameras are almost always the CCTV cameras you’ll find in workplaces, offices, supermarkets and on public transport networks. The lens and other camera components are contained in a clear dome, a design that makes the camera less conspicuous.

The dome cover makes cameras hard to reach, ideal for public settings where vandals might try to cause damage, block the camera, or obscure the lens. It’s also effective at stopping dust or dirt from impacting image quality.

Features of Dome CCTV Cameras:

1. Design: The clear dome protects the lens and blends into the environment, though there can be issues with infrared bounce-back, which reduces image clarity at night.
2. Angles: Dome cameras are most often produced with wide-angle lenses that cover a broader field of view than a single camera, which can mean one dome replaces two alternative units and improves cost-efficiency.
3. Installation: These CCTV cameras can be installed on any wall or ceiling, and though most often used indoors, there are outdoor dome cameras with weatherproof casings.
4. Flexibility: If a site owner wants to change the areas covered by a dome camera, the unit will need to be removed and reinstalled elsewhere.

How Do Turret CCTV Cameras Work?

Turret cameras have a ball-and-socket mount, allowing the camera to rotate in any direction to cover different angles or areas. There isn’t a cover, which can mean the lens can potentially be tampered with, but the greater visibility makes these CCTV units a better deterrent.

Features of Turret Cameras

1. A turret camera is more of a half-sphere shape, with flexible mounts that stand out, are more noticeable and can rotate 360 degrees.
2. Turret cameras with optical zoom functionality can provide both long-distance surveillance and close-up images with equally high resolutions.
3. Most turret cameras are installed on walls or ceilings indoors, or on walls outside.
4. A turret camera can be rotated to adjust the area being monitored.

Which Is Best: A Dome or Turret Camera?

Each CCTV system design varies, and while both dome and turret cameras have ideal applications, businesses can also consider combining camera models or using some fixed CCTV alongside wireless surveillance, depending on the outcomes of their risk assessments.

Although it’s impossible to state with certainty which camera would be optimal for your premises or site, and the risks you need to manage, the lists below summarise some of the situations in which one or the other may be preferable.

When to Choose a Dome Camera

It’s best to choose a dome camera for the following scenarios:

1. To install discreet surveillance that doesn’t attract attention
2. When you need cameras that blend in with the aesthetic of your business
3. If you’re looking for a camera that will operate reliably without being exposed to environmental damage, vandalism or tampering
4. When you need a camera with good low-light functionality

When a Dome Camera Is Less Suitable

A dome camera may not be suitable in the following scenarios:

1. For sites and businesses that want a visible deterrent
2. When risks and areas of coverage are changeable, and CCTV cameras will need to be repositioned
3. If infrared is a key requirement and takes precedence over other features

When a Turret Camera May Be Ideal

It’s best to choose a turret camera for the following scenarios:

1. If you’re looking for cameras that you can adjust and rotate to improve coverage or focus on specific assets or entrances
2. When you need to be able to monitor activities over longer distances and close up
3. For premises in need of higher-profile CCTV that prospective intruders can see
4. If you need excellent nighttime vision and cameras with low-light performance

Reasons Not to Choose a Turret Camera

A turret camera may not be suitable in the following scenarios:

1. When you require discretion and don’t want CCTV to be obvious
2. If you’re installing cameras outdoors and need to protect lenses from the elements
3. In any situation where there are risks of criminal tampering or vandalism

Further information and more tailored guidance are available from our professional CCTV surveillance consultants.

Frequently Asked Questions

Is it Better to Install Turrets or Dome Cameras?

The right answer will always depend on the specifics of your site and security risks. Still, in general, turret cameras are ideal for busy and multi-use sites, where operators can zoom in or pan out and access clear night-vision feeds.

Dome cameras are more suitable for discretion and are resistant to vandalism and tampering, which is why they’re so widely used in offices, cafes, gyms, hospitality venues and workplaces.

What Are the Drawbacks of Dome CCTV Cameras?

The dome covering the camera lens can accumulate condensation, which is difficult to clean, and, depending on the light sources, infrared can bounce back into the clear casing, reducing the clarity of nighttime CCTV feeds.

What Is a Turret CCTV Device?

Turret cameras are so-called because the camera rotates and swivels, covering 360 degrees within a single unit. The camera has a three-axis ball-and-socket mount that allows for movement.

Can Turret Cameras Come With Built-In Audio Recording?

Yes, although it’s important to be cautious around any CCTV surveillance that incorporates audio, as this can breach data privacy rules if you’re fitting cameras in a workplace or a public setting where people have a right to privacy.

However, cameras can feature audio-detection functions that don’t necessarily record conversations but can pick up on noise signals that trigger an alert or prompt a responder to investigate the cause.

While it’s advisable to speak with a qualified CCTV engineer if you can’t find a quick fix or are having consistent issues with your CCTV, some basic problems should be simple to resolve.

This guide highlights the most common challenges business owners encounter with their CCTV and summarises the likely contributing factors to help you diagnose the underlying fault.

Fixing Common CCTV Faults: Key Takeaways

• Modern CCTV is designed for flawless operation. Sudden issues or outages may be due to a lack of CCTV maintenance, which means a service visit may be urgent.
• Common problems with CCTV also relate to power: power cuts, intermittent supply, or damage to cables and wires that will need to be replaced.
• If you’ve tried to fix your CCTV but haven’t been successful, the best advice is to call a professional, as attempting to reset devices or reconfigure settings could make a straightforward problem harder to fix.

What are the most common problems with CCTV?

While it’s impossible to be certain about the issue without inspecting your system, the cheat sheet below might help you figure out what to check, based on the nature of the problem or fault.

The list below highlights some of these problems and looks a little closer at the possible resolutions.

Other common problems with CCTV

1. My CCTV Feed Is Flickering

Hardwired CCTV systems that rely on mains electricity are most often impacted by power cuts, a poor power supply, or damaged wires that mean images can flicker, glitch, or cut out – either now and again or repeatedly.

That might be due to wildlife damage, such as wires being chewed through, a malfunction in your camera or cabling, or interference.

You can visually inspect all cables and power connections, disconnect and reconnect your camera, and ensure there aren’t any devices positioned very close to your CCTV that could be interfering with the signal.

If you have ongoing issues with your power supply that are impeding your ability to protect your business or facility, you might want to consider wireless CCTV as an alternative.

2. I’m Not Getting CCTV Notifications on My Mobile

Most modern CCTV solutions can transmit notifications via 4G or 5G, which removes reliance on an internet connection, but losing remote access is often due to your configuration, not the equipment itself.

In some instances, you’ll find a VPN connection is blocking the feed; in others, you’ll need to reset cloud access permissions.

If your camera hasn’t been configured properly, this will also need to be looked at, including gateways, local networks, and IP addresses.

3. I Can’t See a Clear Live Feed Through My CCTV Stream

One of the biggest issues with CCTV is that cameras aren’t providing the right coverage, leaving blind spots that are easy to exploit. Therefore, if you only have a partial view, it’s worth having the camera reprogrammed by a technician. [1]

You could also discover that something simple like a tree branch is obscuring the live feed, remembering that if your cameras are using digital zoom, even small objects can disrupt the lens.

A more serious problem is damage to the lens or camera itself, because damaged sensors won’t be able to display live feeds, even if the camera has an adequate power supply.

4. My Night Vision Features Aren’t Working

Night vision and infrared LEDs are now common features and ensure you can monitor sites and movement outside working hours. They are used everywhere, from residential homes to supermarkets and retail centres, where theft is significantly more likely overnight.

If you’ve lost night vision, it could be a configuration error with the camera, which means the system isn’t automatically switching to night mode. This is usually controlled by ambient light settings.

This is also another problem that can be caused by insufficient power, as infrared LEDs require extra power to function, or by damage to the LEDs, which may need to be replaced.

How to fix your CCTV problems

Most CCTV issues can be resolved by identifying whether the fault is caused by configuration, power, connectivity, or physical damage.

Problems such as incorrect colours, black and white images, or poor night-time performance are often linked to misconfigured settings, insufficient lighting, or faulty infrared components, all of which can usually be corrected through recalibration, improved illumination, or component replacement.

Interference-related issues, including lines on the video feed, humming noises, or flickering images, are commonly caused by damaged cabling, poor grounding, or unstable power supplies. These faults typically require cable inspections, electrical checks, or the installation of surge protection and stable power sources to restore consistent performance.

Connectivity and recording failures, such as lost remote access, missing footage, or choppy video, are usually network-related. Resolving these issues may involve correcting IP or VPN settings, increasing bandwidth, upgrading storage capacity, or ensuring the system is correctly integrated with the network.

Regular maintenance and professional system checks are key to preventing these problems from recurring. By routinely testing cameras, power supplies, cabling, and software settings, CCTV systems remain reliable, effective, and fit for purpose as site conditions change.

When Should I Try to Fix a Problem With My CCTV Myself?

Some CCTV outages are quick and simple to fix, often because a cable or plug has become loose; in that case, it’s just a matter of correcting the connection, which should get your surveillance back in action.

However, it’s also common for CCTV to be poorly configured, usually due to a DIY installation, so if your CCTV is fairly new or has just been fitted, that is more likely the culprit. [2]

‘While there are some minor issues that you’ll be able to correct yourself, we can’t overstate the importance of avoiding any electrical wiring or trying to fix a camera if you’re not 100% confident you know what the problem is and have the skills and equipment to do so.

It’s far better to call a professional engineer who can diagnose the fault quickly and replace components as necessary rather than injure yourself or make the problem worse.’

We can help fix your CCTV Problems

Many common CCTV problems stem from poor maintenance, outdated equipment, or systems that are no longer suited to how a site is used. Without regular checks, faults can go unnoticed, footage quality can degrade, and protection can fail when it is needed most.

Clearway provides professional CCTV maintenance to keep systems reliable, compliant, and performing as they should. From routine inspections and fault diagnosis to upgrades and ongoing support, Clearway ensures your CCTV continues to protect your site effectively, day after day.

Frequently Asked Questions

How Can I Tell if My CCTV Isn’t Working Because it’s Been Tampered With?

Visual inspections should make it obvious whether a wire has been cut or disconnected, but jamming is less easy to identify. If you’re worried that criminal activity could interfere with your surveillance, it’s best to call a security specialist urgently.

How Long Should CCTV Cameras Last on Average?

It’s difficult to give a direct answer because there are thousands of CCTV models, systems, and designs, each with very different lifespans. As a rough estimate, even a basic camera should last at least a few years, though a lack of regular maintenance could reduce that.
