Over the fence or through it: zoned detection for a substation

The Challenge

The operator needed to protect against climbing over and breaking through the perimeter fence, and to guide the camera operator to a defined area when an alarm came in: zones of no more than 50 m, with every gate on its own zone.

The Solution

Two complementary layers. An Electro-Fence™ topper above the physical fence deters and detects climbing over, while Flexiguard™ vibration detection on the lower fence picks up attempts to break through the structure. Seven energiser cabinets and Flexiguard™ analysers divide the perimeter into 14 zones, with the pedestrian and double gates on dedicated zones, and every alarm calls up the linked CCTV for that zone.

The Result

An alarm now names the affected zone, the CCTV system activates for that section of fence or gate, and the operator can react to a confirmed event with confidence rather than searching the whole boundary.
