RF900 Perimeter Fence Sensors

Solar powered intrusion detection system,It is an optical fiber vibration intrusion detection product designed and developed based on the principle of laser interference.

Product Description

Perimeter Fence Sensors       

Perimeter Fence Sensors is a Dual-zone Fiber Optic Intrusion Detection System designed to detect intrusions into the perimeters and borders on the basis of the principle of M-Z laser interference. It adopts optical fiber vibration sensing technology, to detect and notify any intrusion attempt such as climbing, cutting sabotage the fence or disassembles the system. Solve the problem of equipment power supply, make use of new energy to ensure that the equipment does not power off every day.Furthermore, it has strong anti-disturb ability to eliminate environment nuisance alarms and can be immune to electromagnetic interference, lightning and storms.

The Perimeter Fence Sensors provides both indoor and outdoor deployment, supports 1-2 defense zones; it is suitable for villas, residential, oil depots and other short-distance or less complex perimeter protection.
