Distributed fiberoptic monitoring systems

Critical site security

header

  • RELSEN can detect, classify and localize the targeted activities (pedestrians, car moving’s, digging attempts etc.) all over the border of the controlled perimeter
  • RELSEN guarantees the spatial resolution no less than 5 meters in process of the targeted activity detection and can operatively transfer the targeted activities coordinates to the emergency center
  • RELSEN system has the open interface and it can be easy integrated into any existing perimeter security system

RELSEN accuracy results

Here PCC – Probability of the correct classification, α – Type I errors, β – Type II errors.
