The distributed fiber optic vibration measurement system uses optical cables as sensors, which can be buried underground, tied to guardrails, or embedded in walls along the perimeter of the prevention area. When an event occurs, the vibration or pressure generated can be detected by the optical cable and the external intrusion signal can be transmitted to the signal processing center. Finally, the control center issues a corresponding alarm and provides the specific intrusion location. The system has high sensitivity, and due to the built-in intelligent judgment system, it can intelligently identify and classify intrusion behaviors, with a high alarm rate and extremely low false alarm rate. Commonly used in airports, warehouses, military restricted areas, border lines, railway lines, power stations, and military facilities.
