The system adopts Brillouin principle, uses standard single-mode optical cable as sensor, and lays the optical cable along the perimeter fence of the storage tank area, which can sense the vibration signal around the perimeter in real time, accurately locate and alarm abnormal vibration events such as personnel climbing, crossing and destroying the fence, so as to realize the safety protection of the perimeter. At the same time, the system can be linked with the video monitoring system to form a comprehensive anti-theft and anti intrusion monitoring network.

Technical features:

（1）The system uses ordinary communication optical fiber cable as sensing unit, which has low cost and convenient maintenance compared with similar products. The detection of long-distance and large-scale perimeter defense area is realized by using the change of light characteristics caused by external vibration.

（2）Flexible configuration. It can form a small perimeter alarm system, a large alarm system, a multi-level alarm receiving center and an independent alarm system.

（3）The network collector adopts the optical fiber relay transmission mode, which can not only ensure the anti-interference and anti lightning performance of transmission, but also realize the long-distance transmission.

（4）The network camera can directly transmit the video signal to the control room through the network optical cable vibration detection and alarm system, without laying additional signal transmission lines for the camera.

（5）The maximum detection length of each defense area can reach 10km.

（6）The system uses optical cable as passive detector, which effectively avoids lightning interference, and is suitable for inflammable, explosive, strong electromagnetic interference and other places.

（7） It is suitable for all kinds of complex terrain and can detect irregular perimeter defense area.

（8）Optical cable has high sensitivity, that is, it can be directly laid on all kinds of iron net, iron art, plastic steel, brick wall and irregular wall, or directly buried under all kinds of ground to form a concealed protection system.

（9）Long service life and small maintenance.
