Perimeter Alarm Systems and Sensors

Clearway provides perimeter alarm systems that detect intrusions and alert security teams to prevent unauthorised access.

Discovering that your perimeter has been breached, especially if this wasn’t detected until serious damage or theft has occurred, is distressing at best. In many cases, intruders will attack sites, vacant properties, and premises overnight, and you may face significant costs, delays, and concerns about repeat incidents.

Our advanced perimeter alarm systems and sensors eliminate this threat, with wireless installation, high-volume sirens, 24/7 monitoring and immediate alerts when any suspicious movement around your perimeter is detected.

Our Perimeter Alarm Systems and Sensors

As with every aspect of your security, you need alarms, sensors, and motion detectors tailored to your specific needs, which can detect all types of intrusion attempts while staying within budget. We’ve shared some of our most in-demand perimeter security solutions below to give you an idea of the options.

inView Detect Perimeter Security Alarms

inView Detect, our leading perimeter intrusion detection system, is a reliable alarm system in the event of a security breach alongside your perimeter.

inView Detect is equipped with effective alarm features to promptly notify and alert security personnel when an intrusion is detected along the perimeter. Features include:

An Audible Alarm: In the event of an intrusion, inView Detect includes a highly audible alarm with a 120 dB siren. This audible alarm serves as a powerful deterrent, immediately notifying anyone in the vicinity of a security breach.
Visual Alarm Indicators: In addition to the audible alarm, the system features visual alarm indicators. Four flashing blue LED strobes activate upon detection, providing a visible signal of the security breach. This visual aspect enhances the deterrent effect and helps draw attention to the specific area where the intrusion has occurred.
Alert Verification: Upon activation of the alarm, the system swiftly verifies the alert through its integral AI system. A series of images is captured and sent to the NSI Gold Cat II Alarm Receiving Centre (ARC) for verification. This verification process ensures that the cause of the alert is confirmed, and appropriate security protocols can be immediately followed.

More about our PIDS System

Video Verified Alarms for Empty Site Perimeters

Video verified alarms are autonomous, wireless alarm systems specifically designed for site perimeters, especially those without access to mains power. These systems are highly effective in securing site perimeters, where false alarms are common and the cost and effort to investigate each alert can be prohibitive.

Each alarm unit on the perimeter detects movement or unusual activity instantly, capturing a series of images as a short video clip. This helps identify the cause of the alarm, enabling security responders to react appropriately with comprehensive knowledge of the evolving situation.

Perimeter Alarm Systems for Properties

While perimeters commonly cover areas of land, access routes and boundaries, perimeter security also applies to buildings and units, with a range of options based on scanning all potential entry points.

There are multiple ways to configure an alarm network, including sensors, cameras, sirens, and high-decibel alarms, with sensors placed strategically, such as across windows, roller shutter doors, or other entry routes away from main entrances.

PIR (passive infrared) motion sensors are an affordable and practical tool in perimeter alarm systems, capable of detecting temperature changes and identifying body heat signals to raise the alarm even when movement is out of sight.

Other options include glass break sensors, door and window sensors and integrated environmental sensors that can activate an alarm signal when smoke, fire or a gas leak is detected.

More About Perimeter Alarms

Vacant Property Alarms

Construction sites, empty commercial units, and vacant properties are high-value targets for vandals, criminals, and squatters, and perimeter alarms are essential for addressing any illegal access swiftly.

Most empty properties lack a reliable mains electricity supply. A wireless alarm system for outdoor spaces, construction sites and vacant units is advisable, with tamper-proof alarm signals and high-capacity battery packs that do not require fixed wiring.

Perimeter alarms are adaptable. At Clearway, we are happy to walk you through the various options and offer the most effective alarm system to protect against all major threats, whether you’re looking to secure a vacant property, a standalone building, or a large construction site that requires security protection outside of normal working hours.

We can also provide short-term perimeter alarms and CCTV surveillance to safeguard your site or vacant property during periods of increased risk or to prevent intrusions while a location is unsupervised.

Perimeter Alarm System Maintenance

Ensuring regular maintenance for perimeter alarms is essential to uphold a secure environment. Well-maintained perimeter alarms not only serve as a strong deterrent against unauthorised access and potential breaches but also facilitate prompt anomaly detection, minimising the risk of potential losses.

Proactive maintenance enhances operational reliability, reducing the likelihood of malfunctions and ensuring consistent security coverage. Timely issue resolution helps prevent significant problems and associated costs, emphasising the importance of investing in perimeter alarm maintenance as a critical element of overall security and risk management for property protection.

How Perimeter Alarm Systems and Sensors Work

From Call to Hire, getting your site secured is straightforward

1. Motion and Movement Detection

Alarms can be fitted with varied sensors that pick up on even covert activity, with environmental, glass break, PIR and door and window sensors.

2. Verification of the Cause

AI-supported visual verification determines the reason for the alert, dismissing false alarms and escalating genuine security events.

3. Immediate Deterrent Action

Flashing strobes and a 120 dB audible siren notify intruders that they have been detected, and, in most cases, mean trespassers will exit the site to avoid being apprehended.

4. Rapid Response Initiated

Notifications are circulated to all relevant parties via our ARC response centre, including the police and fire response teams, your on-site security guards, or mobile patrols.

How to Organise a Perimeter Alarm Installation

1. Site Risk Assessment

Our team of security experts will assess your premises, identify risks, and recommend to you a custom perimeter alarm system solution to help secure your commercial assets.

2. Alarm and Sensor Selection

We’ll offer personalised recommendations, because the ideal perimeter alarm systems depend on your location, neighbouring properties, and other factors – for example, if you have existing fencing with vandalism-proof paint or anti-climb resources, a simple motion detector alarm may be sufficient.

3. Professional Installation and Integration

Clearway’s experienced technicians will move quickly to organise your alarm installation, ensuring you are confident using and operating your new perimeter controls.

4. Ongoing Monitoring

Regular maintenance of perimeter alarms is crucial for maintaining a secure environment, as it enhances deterrence against unauthorised access and ensures prompt detection of anomalies.

Key Problems Perimeter Alarm Systems and Sensors Can Resolve

It can be extremely difficult to protect perimeters, with many backing onto open land or access routes that make it easy for criminals to breach your boundary, but with a prohibitive cost associated with building fences and walls.

This is where wireless, rapidly deployable alarms prove invaluable, offering an immediate and reliable way to protect boundaries of all sizes, for any period.

1. You’re Worried About a Perimeter That Is Currently Left Unprotected, Allowing Intruders to Trespass Undetected

Your business, site, or premise has exposed boundaries or is adjacent to easily accessible land or roads, and you haven’t implemented any security measures that will immediately detect an intruder when they set foot on your property.

2. You’re Reliant on Basic PIR Systems, Which Cause Frequent False Alarms and Little Trust in Alerts

Ongoing issues with false callouts, often in the middle of the night, or alarms that have no discernible cause mean your existing systems are less than reliable, and you’re finding yourself ignoring potentially legitimate alerts.

3. You’ve Experienced Criminals Cutting Fences or Forcing Entry Without Any Alarms Being Triggered

There have already been attempted or successful break-ins, and you need a way to ensure that if this happens again, you’ll receive a rapid alarm before a trespasser gains entry to your site.

4. You’ve Had Issues With Delayed Detection, Which Means Intruders Are Only Noticed When They’re Already Inside the Property

You’ve had serious intrusions where trespassers have been able to get to your property, equipment, materials or other assets – and you’ve only realised your perimeter has been breached after the fact.

5. You’re Managing Wide or Complex Perimeters That You Cannot Monitor Manually Without Extended Alarm Coverage

Larger perimeters around agricultural land, warehousing depots, retail centres and construction sites cannot be continually monitored by guards, and you need to be able to protect every centimetre of your perimeter around the clock.

6. You’re Conscious That a Lack of Visible Deterrents Like Sirens or Strobes Could Be Encouraging Opportunistic Breaches

You are trying to manage elevated risks or ongoing threats of intrusion and want to ensure there is a clear, visible indication that live security monitoring is in place – stopping criminals before they breach your perimeter.

7. You Know That Your Alarm Systems Are Vulnerable to Tampering or Signal Jamming

You manage or own a high-value site where organised criminals use signal jamming to bypass your security controls, and want the peace of mind that you have anti-signal jamming and encrypted communications.

8. Your Vacant Property or Remote Site Is Often Being Targeted at the Perimeter

Intruders have been ‘testing the water’ to see how far into your boundary they can get before being challenged, and you need to improve your security before this escalates into something more serious.

9. You Don’t Have Any Integrations Between Your Alarms and CCTV, Which Leaves Perimeter Breaches Unverified

You’re left guessing whether an alarm is genuine or not, causing wasted resources attending false alerts – something you need to put a stop to quickly to ensure you can review footage or captures to confirm the right response.

If you are experiencing these or any similar problems, we strongly recommend contacting our advisers to ensure your perimeter is properly protected as quickly as possible.

What Do Our Security Experts Say?

Our UK Sales Director, Kelvin Danton, explains why detecting perimeter breaches is so important.

Stopping intrusions before they occur, and ensuring criminals can’t bypass main entrances and guarded routes through open land is essential – and something that perimeter alarm systems make cost-effective and simple to implement.

Perimeter alarms create a virtual fence line that is communicated with visual deterrents, such as strobes, ensuring that any prospective trespassers can see that they cannot enter any part of your perimeter without being detected, recorded, and apprehended.

Frequently Asked Questions

Got a question about our site security? Read our frequently asked questions.

What is a perimeter alarm system?

A perimeter alarm system is a security solution designed to detect and alert to unauthorised access or breaches along the boundaries of a property. It typically includes sensors, alarms, and monitoring technology to provide comprehensive protection and immediate notifications of any suspicious activity.

What is the most common perimeter protection device?

The most common perimeter protection device is the motion sensor, which detects movement along the boundary and triggers an alarm if any suspicious activity is detected. This is often combined with other technologies, such as cameras and lighting, to enhance security and provide comprehensive monitoring.

How does a perimeter security alarm work?

A perimeter alarm works by using sensors to detect unauthorised access or movement along a property boundary. When the sensors identify a potential breach, the system triggers an alarm and sends notifications to security personnel or a monitoring centre for immediate response.

What makes a perimeter alarm different from a standard intruder alarm?

Basic intruder alarms work with networks of sensors that detect movement and sound an audible alarm. They are often used with door-break sensors, for example, and can emit an alarm or transmit the alert to a monitoring service or site manager.

The drawback is that alarms can be tampered with, signals can be interrupted or jammed, and they can only monitor the specific space or area where they are installed and connected to sensors.

Perimeter alarms are advanced, highly responsive units with full-scope coverage, anti-signal jamming technology, and wireless functionality, which enables us to install these alarms across perimeters of all sizes, without cabling and with no risk of tampering.

How do visually verified alarms reduce false callouts?

False alarm filtering can save a great deal of time, stress and cost by confirming the cause of the alert and standing down guards and patrols or checking the reason for the alarm before contacting the police. This ensures false callouts are rare, if not non-existent.

Can perimeter alarms be installed without power or an internet connection?

Absolutely – it’s commonly difficult, if not impossible, to protect an entire perimeter with security systems that depend on mains electricity or a continual WiFi signal. Our perimeter alarms operate with wireless, solar or battery power and are designed for use within off-grid sites.

How loud are Clearway perimeter alarms?

Extremely loud. Our inView Detect device is fitted with a 120 dB audible siren, which is impossible for any intruder to disregard. This is equivalent to the sound of a chainsaw or a clap of thunder overhead, but it continues to sound until deactivated, and is accompanied by flashing blue strobe lights.

Do perimeter alarms integrate with CCTV and security monitoring systems?

Yes! It’s essential to have a verification method that enables our responders to determine whether an alarm has been triggered by harmless wildlife or a person attempting to crawl under a fence or climb a wall.

For higher-value premises or where a perimeter is difficult to physically protect, a more advanced CCTV surveillance system with automated alarm signals, tamper-proof fixings and pan, tilt, and zoom functionality may be advisable.
