Fence Sensor Frequently Asked Questions

What is a fence sensor?

Intrusion detection sensors are the key to effective perimeter security. Fence-mounted sensors detect and locate intruders before they enter the fence. The system is cable, fiber optic, or accelerometer based and works with most fence types including chain link, welded mesh, steel mesh, and fencing. The sensors enhance the security value of the fence by detecting attempts to cut, climb or otherwise breach the fence. Fence sensors are also available for non-standard fence types as well as interior and exterior walls.

What is a fiber optic fence sensor?

Fiber optic sensors work by transmitting laser pulses into an optical fiber and accurately measuring the tiny light reflections that occur along its length. Fiber optic interference caused by fence vibration changes the amount of light returned from that point. Fiber optic sensors are unaffected by lightning and electromagnetic interference and require no conductive components or grounding points in the field.
