Perimeter Security System

What if your perimeter did more than mark a boundary? Gallagher's perimeter security system delivers intelligent, layered protection from curb to core on one platform that deters threats before they happen, not just after. Standards-compliant and battle-tested at the highest-security sites in the world, this is innovation from the edge.

Innovation from the edge

Your perimeter security fence is your first line of defense, and your first opportunity to deter, detect, delay, and respond to a threat. For commercial and industrial operators, that means fewer chances for theft, vandalism, sabotage, and operational disruption, because threats are stopped before they reach your people, buildings, or critical systems. 

A modern security fence does far more than mark a boundary.

It is a layered, connected system of deterrence, detection, intelligence, and integration that adapts to each site and grows with it. Gallagher Security brings those layers together on one platform, so protection at the edge becomes an informed, coordinated response at the core.

What the right perimeter protection system does for your site

  • Stop incidents before they start
    Layered deterrence and detection give intruders no easy way in and give your team early warning, so you prevent breaches instead of investigating them afterward.
  • Measurable risk reduction
    Fewer incidents, fewer false dispatches, and lower operational load add up to a cost case your finance team can see
  • Evidence for compliance and duty of care
    Detailed event records and consistent monitoring help you meet your obligations and show the site is protected.
  • Fewer patrols, lower operating cost
    Reliable detection at the fence line reduces the need for routine guard patrols. That lowers cost and removes the human error that comes with manual checks, while your people cover the whole site from one screen.

Core features of Gallagher’s perimeter security system

A fence on its own only slows an intruder down. A perimeter is strongest when every layer, from the physical barrier to the electronic detection and software behind it, works as one system.

Visible physical deterrent
High-tensile pulse fences form a strong visual barrier and deliver safe, short pulses that deter intruders

Icon - Intruder Alarm

Instant intrusion detection
Sensors alert you the moment a perimeter fence is touched, so your team can respond fast to a breach

One connected view from curb to core

Gallagher Security's integrated perimeter security solution is a native, core product of Command Centre, the same software that runs access control and intruder detection. There is no switching between systems that were never built to work together, and no blind spots where one system ends and another begins.

That connection changes how security teams respond. The moment a sensor picks up movement or a change in wire tension, the same view shows where it happened and lets a guard check the zone on camera before deciding what to do. A response that once meant checking several consoles now takes seconds. 

Because perimeter is a core part of Command Centre, not a separate product bolted-on afterward, nothing quietly stops working after a software update and nothing gets lost in the gap between two vendors' systems. And the same platform covers a single zone or an entire multi-site operation, so your protection grows with your site and everything you have already invested in keeps working.

Perimeter Security FAQs

  • What is a perimeter security system?

    A perimeter security system protects the outer edge of a property using layered fencing, sensors, and cameras. Modern electronic perimeter security systems combine these into one platform that stays alert around the clock, deterring, detecting, delaying, and responding before an intruder reaches the buildings inside.

  • Are Gallagher perimeter security solutions safe?

    Yes. Gallagher Security designs its perimeter solutions to meet international safety and electromagnetic compatibility standards, and every energizer is tested in accredited laboratories. The result is protection that is effective while keeping risk to people and animals low.

  • Can Gallagher's perimeter security system be retrofitted to existing fencing infrastructure?

    Yes. Gallagher Security's perimeter systems work with most existing fence types, so a site can add detection and deterrence to infrastructure it already owns and upgrade security without a full fence replacement.

  • How do Gallagher’s electric fences work?

    Gallagher electric fences use sensors that continuously measure wire tension and monitor for vibration. That data lets the system tell a genuine intruder apart from wildlife or harsh weather, and it sends an instant alert to designated personnel when a real threat is detected. On an energized fence, regular safe pulses deliver a short shock that makes the fence very difficult to climb.

  • How does Gallagher integrate with other security systems?

    Gallagher Security unifies access control, perimeter, and intruder alarms on one platform, Command Centre, for connected protection from curb to core. Command Centre also integrates with video management, vehicle access control, and many third-party systems, giving operators stronger situational awareness across the whole site.

  • What industries benefit from Gallagher perimeter security?

    Perimeter security matters most for critical infrastructure such as utilities, energy, and data centers. Gallagher Security also protects government and defense sites, transport and logistics operations, storage facilities, correctional facilities, and other high-security commercial environments.
