External perimeter systems can be extremely challenging due to the variety of external environments, physical restrictions, geographic and environmental conditions. We have experience across a wide range of environments and applications and can advise on the best solution to meet requirements.

We are familiar with most external sensors, including fence mounted alarm systems, microwave, active and passive infra red, buried field based sensors, laser and RF radar. We can apply the right technology to the application to provide a robust solution taking into account Probability of Detection (PD) and False Alarm Rate (FAR) that affect the selection of the right technology for the application.

Perimeter systems will generally require alarm verification by CCTV, and we are able to recommend solutions to meet the requirements up to Government approved standards.
