What is perimeter security? Here’s why it’s so important for your site or empty property

Site owners and company managers have often focused their security efforts on properties, doors, windows and entry points, leaving a large, vulnerable space unprotected between a facility and its boundary. When it comes to perimeter security, though, what can we say? Relying exclusively on internal security alerts when assets and outbuildings are readily accessible might lead to needless exposure.

Adding safe, technologically sophisticated perimeter protection is a fantastic option. It gives owners and managers real-time alerts when an alarm is raised and allows security responders to solve concerns actively and preemptively. 

How do you implement perimeter security?

When combined with CCTV monitoring, intrusion alarms on buildings and access gates, and environmental alarms like smoke and fire detectors, perimeter security can function as a stand-alone alarm system or as a crucial component of a larger network of protection. These sensors pick up motion, vibrations, footfall, and vehicle activity. They are often positioned at the perimeter’s furthest border.

Automated gates, bollards, electric fences, and PID security, which instantly sends an alarm to our expert responders stationed at our Alarm Receiving Centre (ARC) or on-site security personnel, are examples of these. Remember that perimeter security doesn’t always require technology; for example, solid barriers might be used to keep cars out of a perimeter.

We’ll examine the advantages in a moment. Still, the main reason perimeter security is effective is that it alerts the appropriate responders immediately to anything suspicious, out of the ordinary, or unexpected, giving them time to take action before an intruder reaches a building, warehouse, or car park. Perimeter security is often neglected at commercial sites, projects, and complexes due to the high cost or difficulty of obtaining the broad area monitoring technology that was once common.

Modern, sophisticated perimeter security systems may cover any area of land by positioning units in key locations, are quickly deployable, use remote and solar-powered battery power, and provide real-time warnings to any remote device. It’s because of this feature that perimeter security devices may be utilised anywhere without requiring a connection to the mains for electricity to function.

Statistics and data about perimeter security in the UK

As the risks of theft, vandalism, squatting, and intrusion become more widely recognised by businesses, property owners, and site managers, a growing number of them are concentrating their efforts on perimeter security instead of waiting for criminal intruders to reach a building or entrance point before setting off an alarm.

The perimeter security industry is expected to reach a value of over £124 billion in eight years, growing at a compound annual growth rate of 8.3% until 2032 on a global scale.

The latest data from the government’s Crime Against Businesses report indicates that:

  • The likelihood of crime targeting publicly accessible premises is higher than that of non-publicly accessible ones (21%), with 34% of targeted places having public access points.
  • The majority of recorded crimes were reported by medium-sized businesses, accounting for 38% of all businesses with between 10 and 49 employees. About 26% of bigger locations with 50 or more employees and smaller organisations reported criminal activity, illustrating how medium-sized locations with less sophisticated protection are frequently seen as prime targets.
  • With 15% of all reports, theft was the most frequent crime in 2022. It was followed by physical assault or threats, vandalism, and burglaries and attempted burglaries.
  • The industries with the highest rates of crime were retail and wholesale, accounting for 42% of all enterprises affected over 12 months.


This data demonstrates the critical role perimeter security plays in safeguarding sites of all sizes. 

It also shows how the lack of a secure boundary can expose construction sites, commercial buildings, vacant properties, and buildings situated within open land to a significantly increased risk of criminal activity.

What advantages do Perimeter Security Systems offer?

We’ve spoken about a few benefits, but the ability of perimeter detection to cover large regions is perhaps the most important for many organisations, especially those in charge of overseeing unoccupied or empty properties or outdoor work sites without a clearly defined border.

Potential burglars can spot the high-visibility unit of our automated, deterring inView Detect system from a distance. Each device monitors a range of up to 1,700 metres and offers 360-degree coverage; by deploying additional units, you may increase the intrusion detection system’s range to 2,000 metres.

Three principles form the foundation of excellent perimeter security:

  • Detection: Owning a dependable, always-on perimeter security device that can recognise any person, car, or movement that needs further examination.
  • Deter: By employing prominent apparatuses that include a 120dB siren housed in a 1.27-meter-tall enclosure that is hard to overlook, together with four flashing LED strobe lights.
  • Delay: Since genuine incursions are promptly discovered and reported, any lingering intruders may be stopped before they have a chance to steal or break in and inflict actual harm.


Perimeter detection functions as a first line of defence and raises the alarm quickly, allowing you to challenge the intruder or contact your security teams or the emergency services as necessary: this is instead of waiting for an intruder to break into a compound, access your inventory or reach your building.

Which commercial sites or properties need perimeter security?

concrete bollards with barrierFor a long time, high-risk and restricted-access locations, including airports, government buildings, business labs, and compounds, have made significant use of perimeter security. Environments like colleges or schools typically need to make sure that any intruder is quickly located and taken into custody.

But as technology advances and becomes more widely available, we frequently speak with owners and managers of empty commercial space, residential buildings with gardens or back access points, and properties that front on public property or rural areas, as well as company owners in all industry sectors. By catching trespassers or intruders at the point of entry and stopping them in their tracks, perimeter security installations may offer priceless peace of mind.
