The distributed optical fiber vibration measurement system uses optical cable as the sensor, which can be buried in the ground along the perimeter of the prevention area, bundled on the guardrail or implanted in the wall. When the event occurs, the vibration or pressure generated can be detected by the optical cable and the external intrusion signal is transmitted to the signal processing center, and finally the control center issues the corresponding alarm and gives the specific intrusion location. The system has high sensitivity, because of the embedded intelligent judgment system, it can identify and classify the intrusion behavior intelligently, and has a high alarm rate and a very low false alarm rate. Commonly used in: airports, warehouses, military restricted areas, border lines, railway lines, power stations and military facilities.
