Wall Vibration Sensors

Vibration sensors are transducers that detect low frequency energy, such as that generated by a physical intrusion attempt. The sensors are designed to detect mechanical vibration caused by such actions as sawing, drilling, chopping or ramming.

 

Principal Drawback

Walls or fencing to which the sensors are attached must have the proper composition and structural integrity to enable vibration to be transferred to the sensors. Certain types of wood, metal and masonry walls and fencing do not transmit vibration effectively enough for reliable intrusion detection.

Other Shortcomings:

  • Nuisance alarms may result if sensors are exposed to vibrations caused by trains, planes, vehicular traffic or vibrating machinery.
  • Sensors require electricity

Fiber Fence Advantages over Wall Vibration Sensors:

  • Sensors do not require electricity
  • Can be calibrated to eliminate nuisance alarms
  • Can be mounted on virtually any type of fencing or wall
  • Not affected by extraneous vibrations
  • Economical to purchase
  • Easy to install
