Perimeter Intrusion Detection Systems are systems used in an external environment to detect the presence of an intruder attempting to breach a perimeter. With the one of 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 RaySense System uses typical single mode fiber optic cable as a powerful vibration sensor. RBtec uses different technologies such as Distributed Acoustic Sensing (DAS) Technology and Distributed Vibration Sensing (DVS) Technology for different applications on how to monitor a fiber optic. The fiber optic cable becomes extremely sensitive to pressure and motion, capable of detecting minutes vibrations transmitted through the fence, soil or the surface. The RaySense System can monitor the vibration signals along the length of the fiber optic cable and are able location of an intrusion event and classify the specific signatures based on the detection algorithm.
The RaySense System Alarm Process Unit (APU) monitors the optical signal and using sophisticated algorithms; it is able to distinguish between breach, cut climb, walk, vehicle, and non-threatening nuisances. The RaySense System preforms automated optical calibration on power-up and during operation. This simplifies setup and the system performance will not diminish with time; the APU only minimal to no maintenance.

The RBtec Pin 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 is ideal for reliable perimeter security of 5-100km/3-62miles through a single fiber-optic cable, detecting and locating within 3-20m/10-60ft 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 (loop) 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.
