Perimeter Security System Monitoring Application

Application Theory

Distributed Optical Fiber Perimeter Security Sensing System
Sensing components: The sensing cables are the core components of the system. By quickly detecting touch, pressure, and vibration, it can monitor activities such as climbing, cutting, and walking.
Cable structure: The sensing cables feature a special core layer and protective coating, ensuring normal operation regardless of external weather conditions or harsh environments.
Principle of operation: When light signals are transmitted through the fiber, the system software detector processes the phase of the received light signals. When the sensing cable is disturbed by touch or vibration, the transmission mode of the light signal changes. Touch, vibration, or pressure will cause morphological interference, resulting in changes in the phase of the light signal. The receiver detects phase changes, determines the intensity and type of interference, processes the detected signals, and judges whether the interference meets the criteria for triggering an "event".
Installation methods: The sensing cables can be installed using methods such as hanging nets, buckle nets, wall embedding, wall hanging, and underground burial.
Alarm function: When intrusion or damage is detected, the system will immediately issue an alarm.
