Perimeter radar explained: detection beyond the fence

APS Technical Team · 30 March 2026 · 5 min read

Perimeter radar has transformed the way large and open sites are protected. By detecting moving targets across open ground, radar provides early warning long before an intruder reaches a fence or building.

Omni Guard Radar measures both the range and bearing of a target, allowing the system to plot its position and track its movement in real time. This makes it possible to distinguish a person walking, running or crawling from environmental clutter.

When integrated with PTZ cameras through Multisys®, a radar detection automatically slews a camera onto the target, giving operators instant visual verification and dramatically reducing response time.

For solar farms, mining operations, ports and pipeline approaches - anywhere with large expanses of open ground - radar is often the most cost-effective way to achieve reliable, wide-area detection.
