RaySense Fiber Optic Perimeter Fence Security System

The LONGEST Fiber Optic Perimeter Fence Intrusion Detection System in the market.

  • Up to 100km/62miles per processing unit in loop configuration.
  • Up to 50km/31miles per processing unit in straight line configuration.
  • Within 3m/10ft resolution over the entire perimeter.
  • Signature based detection.
  • Can be used on the fence and underground with same cable and controller.
  • No electronics or power required in the field.
  • IP based Remote control and monitoring – Software based zones.


With the longest fiber optic monitoring capabilities in the market the RaySense provides 100% perimeter coverage for long range applications with no gaps between sensors, the cable is the sensor.
The system detects and locates intrusions based on signature data base to avoid any false.

Long range fiber security system requires no power in the field and installation minimizes the need for trenching and expensive installation methods.
The RBtec Point Intrusion Detection System is the most cost-effective, high-performance solution for protection of long perimeters and other infrastructure.

Deploying RaySense fiber optic intrusion detection system provides reliable perimeter security for up to 100km/62miles through a single fiber-optic cable, detecting and locating within 3 meters over the entire perimeter. Networking additional controllers provide unlimited reach. Seven different levels of actual physical sensitivity, through the cable configuration, optimize the system performance for different infrastructure requirements such as: chain link fence, buried cable, gates, or wrought iron barriers.

Return on your investment

Utilizing fiber-optic cable, the system is the most economically competitive technology currently available for long distances. Requiring only a single alarm processing unit (APU) to cover up to 100km/62 miles if the cable starts and ends at the same point or 50 km/31 Miles in straight line combined with a rugged fiber-optic sensing cable, results in the most cost-effective fence detection solution for large perimeters.
