Perimeter Intrusion Detection System The RF900 is a Dual-zone perimeter 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.The device has only one defense area and is available without external communication network. The project construction is convenient, no network transmission cable is required, the equipment can be managed and monitored remotely, with built-in battery. When the equipment is powered off, it can indicate the power off alarm, and ensure the normal operation of the equipment to achieve 24-hour uninterrupted protection. Furthermore, it has strong anti-disturb ability to eliminate environment nuisance alarms and can be immune to electromagnetic interference, lightning and storms. The RF900 perimeter intrusion detection system 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. Features Zone length is up to 500m. One zone and two zones are optional. Optical fiber length is up to 1000m. Use normal optical fiber cable for telecommunications (GYXTW). Fiber optics can be installed on wire net or underground. Support contact closure alarm output. Detect behaviors of climbing, cutting, sabotage and disassembling. Support rapid fiber cutting detection (less than 1 second). Be immune to electromagnetic interference, lightning damage. ESD and surge protection circuits inside. Ambient working temperature: -40 ~ +70 Adopt ABS engineering plastics. DC12V power supply with consumption less than 3W.
