The TrueSentry Perimeter Intrusion Detection System uses a use a thin, inert fiber optic cable as the sensor.  When you attach the sensor cable to the mesh of a perimeter fence or strap it to a wall and the system’s corresponding electronic Alarm Processing Unit (APU) detects vibrations from any intruder climbing or cutting through the barrier.

The system is calibrated which allows you to screen out signals from non-threatening events, such as wind or small animals, while optimizing detection of valid signals from intruders.  Intelligent digital signal processors automatically compensates for disturbances from wind, giving you a system that provides maximum zone protection in nearly all circumstances.
