  • BEI Security offers a suite of Fiber Optic Security products which are customizable to meet a broad spectrum of diverse security needs:

    FiberSensor The FiberSensor™ is a versatile system based on the use of fiber optic sensor cable. Intrusion attempts are detected by motion 
and vibration disturbance in the light transmission. FiberSensor can be installed on an existing perimeter fence or barrier or buried underground.


    SmartFence™ SmartFenceTM is BEI Security's premier product designed for the highest levels of security needs. Any attempt to cut, lift, crawl under, climb over or pass through the SmartFenceTM will result in detection. The innovative integration of fiber optic net and cable operates on the principle of light disturbance. The components include the FiberNet™, which detects any attempted intrusion by cutting, and the FiberSensor™ which detects intrusion attempts by sensing motion and vibration disturbance. The FiberSensor™ cable is installed in a split plastic conduit to provide uniform detection and to enhance sensitivity to any fence motion disturbance. Coded infrared (IR) light is sent through the cables from IR transmitters to IR receivers. Any attempted intrusion will trigger an alarm, and monitors in the System Command Center will display and record the intruded zone and all related data.

    MarineNetThe MarineNet™ Perimeter Intrusion Detection System is designed for fresh or salt water use. The system can be configured in two ways: RIGID or FLOATING. The Marine RIGID System is employed when the net is connected to existing structures or solidly set poles. It is well suited for oil rigs and shallow areas. The Marine FLOATING System is used when the net is connected to floating buoys. It is well suited for quick spreading in harbors, for surrounding vessels and offshore deep water areas.

    OptiLoop is a  variable length single fiber optic cable with ST connectors which is threaded through the property that is to be protected. Infrared coded light is pulsed through the cable. Any attempt to remove the protected property will activate an alarm or monitor signal. A disconnection or breakage of the cable will produce visual and audible alarms for immediate response.

    Derived from our unique FiberNet™ continuity sensor technology, the system is false alarm free and is easy to install and maintain. Like the FiberNet™, the OptiLoop offers a 99.99% probability of detection plus a virtually zero false alarm rate!
