FiberPatrol® Buried

FiberPatrol FP6100X fiber optic sensor for buried intrusion detection applications

Using a buried fiber optic cable and a centrally-located sensor unit, FiberPatrol’s advanced technology provides long distance covert detection of intruders, vehicles, and tunneling.

Features and benefits

  • Detects a wide range of intrusion types for up to 80 km (49.7 mi) with an accuracy of ±5 m (±16 ft)
  • Accurately locates multiple simultaneous intrusion events
  • Sensor cable continues to operate up to the point of a cut
  • No electronics, outdoor power, communication infrastructure, or grounding points required in the field
  • EMI and lightning immune
  • Software-configurable detection zones
  • Multiple options for integration with SMS, VMS and PSIM platforms
  • Alarms reported by zone number, cable distance and/or GPS coordinates

How it works

FiberPatrol works by transmitting pulses of laser light into a single-mode optical fiber and accurately measuring the minute light reflections that occur along its length. A disturbance of the fiber caused by ground vibrations changes the amount of light returned from that point.
