Fiber Optic Shotgut Test

Typical impact & abrasion testing can look like this, but We wanted to do more... We know... let's use Our cable for target practice. We'll call this one:


Let's see how it goes,.


fiberDesigned for medium to high security risk installations, the SmartFence integrates BEI Security’s most advanced and proven fiber-optic technologies, the FiberNet and FiberSensor.

Attach the SmartFence to any existing or new perimeter barriers:

  • Chain link
  • Barbed wire or weld mesh
  • Concrete, stone or brick wall palisades
  • Freestanding barrier

AirplaneINVEST IN THE SmartFence:

  • The SmartFence is highly reliable, easy and economical to install and maintain, and features exceptionally low false alarm rates (FAR), high probability of detection (PD), and low price per kilometer.
  • The SmartFence is unaffected by weather and harsh environments, and can be installed underground, near or even in water (fresh or salt).
  • The SmartFence is immune to EMI and RFI.
  • Installed at an airport perimeter, it will not interfere with avionics or communications.

Any attempt to cut, lift, crawl under, climb over or pass through the SmartFence will result in detection.

All BEI Security turn-key systems include our advanced System Command Center to provide immediate and reliable data relating to any intrusion attempt. The SCC is vendorindependent, and may be integrated with any new or exisiting equipment.

fiber optic sensorSeveral key technologies integrate to comprise the SmartFence:

FiberNet, a fiber-optic net constructed of heavy-duty weftknitted single tactical fiber-optic cable.
Alarms are triggered by attempts to cut through the net.
FiberSensor flanks the top and bottom horizontals of the perimeter barrier. It will detect any attempts to lift, crawl under or climb over the perimeter barrier.


The SmartFence is an innovative integration of fiber-optic net and cable that 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 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 FiberSensor 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.
