Security fencing is a great way to deter opportunist intruders, prevent members of the public from inadvertently trespassing, and reinforcing other security measures – actively showing that your premise, land or business is well protected. But there are a number of types of security fencing to consider. 

For many of our clients, whether commercial organisations, public sector facilities or private property owners, the challenge is in deciding which security fencing will prove most effective and make a tangible difference to their site risk profile.

Here, we’ll work through some of the most popular types of security fencing to explain how they work, the types of compounds or properties they are best suited to, and how each solution may integrate with your broader security strategy.


Types of Security Fencing

1. Electric Security Fencing

Long used in the agricultural sector, electric fencing serves several purposes:

  • Livestock and wildlife will not attempt to cross a perimeter where a shock is administered, protecting herds and other assets such as grain or stored feed.
  • Deliberate and inadvertent trespassers will be unable to enter the site.
  • Signage indicating that a fence is electrified acts as a robust deterrent, where few will attempt to touch the fencing to verify whether it is indeed live.

Modern electric fencing delivers an immediate but managed shock and must be professionally installed and wired. This process ensures that shocks are never fatal or have the potential to cause severe injury but are sufficient to protect a site from intrusions.

The installation process is reasonably quick and straightforward, and electric security fences can cover large perimeters or areas of land, hence their use throughout open land and protected nature reserves.

However, one of the caveats is that an electric fence must be properly maintained to remain functional and must comply with all of the applicable regulations, including advance approval from the local council before the barrier can be erected.

Further drawbacks include fire risks if trees or shrubs are left to grow around the fencing and the need to have a continual power source. Many landowners opt for independent solar recharging since mains electricity connections may be vulnerable to tampering or deliberate wire cutting. The cost of powering an electric fence at all times is also a consideration.

2. Perimeter Intrusion Detection Systems

These devices, abbreviated to PIDs, are a cutting-edge security fencing solution, especially where it would be impractical, time-consuming or costly to install physical fences around an entire property.

PIDs are often used in commercial spaces with increased security risks or where the nature of the facility means it needs to take decisive action to prevent any trespasser from approaching buildings within the site undetected. Examples include:

  • Schools, universities, hospitals and local government premises.
  • Business sites with sensitive processes, high-value equipment or elevated security risks.
  • Compounds with strict access control permissions, including airports and warehouses that store items such as currency, minerals, raw materials and metals.

Clearway’s inView Detect PID unit is a great example. It functions as a standalone, autonomous device that can be deployed in any space, indoors or out, and has the functionality to integrate with other alarms, CCTV surveillance, or security systems.

Any movement within the monitored space, including vibrations, approaching vehicles, or a person, will trigger an instant alert sent to on-site security personnel, our Alarm Receiving Centre (ARC), or the emergency services as appropriate.

Benefits of PIDs include fast deployment, autonomous power functions, the ability to adapt and change your areas of coverage at any point, and the option of placing multiple PIDs in a grid to provide a continually supervised perimeter over a site of any size.

3. Heras Fencing Secured With Concrete Barrier Blocks

Heras fencing is a well-known type of security fence constructed with a metal mesh that is often treated with anti-climb finishes. The mesh is lightweight and quick to install for temporary and longer-term use at events, construction sites or alongside highway working zones.

Welded mesh fences are often considered a more appropriate option than railings since the mesh cannot be easily cut, climbed or tampered with. These fences can also be installed at a lower height to prevent children or wildlife from crossing a boundary or fitted at an elevated height to avoid any intrusion risk.

We often suggest using concrete barrier blocks, which act as an anchor and mean that fencing cannot be moved, shifted or tipped over to allow for vehicular or on-foot access. Concrete blocks come in varied sizes, densities and shapes and can be interlinked to create a tough, immovable perimeter.

Concrete barrier blocks are widely used on working sites where it is imperative that cars and larger vehicles do not pass the perimeter line – including on live work zones on major roads and motorways. When fitted at the desired height, length and placement, blocks are also used to guard against ram-raiding and deliberate attacks, providing an augmented level of protection throughout your perimeters.

Using Advanced Perimeter Alarms

Finally, perimeter alarm systems, either used independently or in conjunction with PIDs and fencing, provide the assurance that any suspicious activity or movement will result in an alert being circulated to your notifiable parties.

Many businesses and compounds need a fencing solution that minimises false call-outs but where they have the peace of mind that any motion will trigger an alarm – ensuring a person or vehicle cannot reach a building or access point without being challenged or apprehended.

Choosing the Best Fencing for High-Security Protection

All of the fencing solutions mentioned here have viable use cases and can reinforce your defences while preventing opportunist or accidental intruders from crossing your perimeter. However, the right options will depend on myriad factors, not least your budget, the availability of a mains power connection, and the assessed likelihood that somebody will attempt to breach your defences.

Our security consultants are always on hand to provide further advice about the best fencing, intrusion detection and perimeter alarm systems, depending on the size and nature of your boundary, the types of fencing or security devices you have in place, and the overall site risk profile.

Please get in touch with Clearway at your convenience for more information about any of the fencing discussed here or to arrange an independent risk assessment to help you make informed decisions.
