Optical Fiber Vibration Intrusion Detector

Optical fiber vibration intrusion detector has the feature of position indication,vibration source will be generated when optical fiber is touched, vibrated or squeezed externally,by detecting the weak change of optical signal due to vibration,it can analyze the position and vibration intensity of vibration points on the whole optical path,and alarm will be given at the first time when effective vibration event is extracted.At the same time, it can determine the accurate location of vibration point according to the echo time .

System implementation function:
1,Pipeline protection
Heavy machinery excavators (wheeled and tracked)
Piling work
Blasting (surface and shallow layer)
Hard object impact (pipeline surface)
Agricultural machinery work
Geological disasters such as floods and earthquakes
2,Perimeter protection
Prevent intruders turn over
To prevent the chisel wall,Prevent cutting of optical cable,The vibration signal can be detected by damaging the fence and other damaging media.

When the system gives an alarm, the sound and light alarms at the scene immediately give an alarm. At the same time, the pop-up window in the electronic map shows the alarm location, and the video surveillance of the linkage alarm area (compatible brands: hikvision, Dahua, Yushi) , the video monitoring products provided by users not only can be customized development, but also can provided with products of SDK protocol, users can be their own secondary development.
