Oldcastle Security added Perimbar, an infrared perimeter security system, to their line of perimeter protection products. The system uses prewired towers, which stand between 1 meter and 5 meters high and have a range of up to 50 feet. The towers contain transmitters that collect energy from receivers up to 492 feet away.
When an intruder breaks these beams, an alarm is set off. It cannot be covered, masked or blocked without setting off the alarm. The system can be added to an existing physical barrier by placing it inside of or on top of the perimeter. An optional beam pattern can be activated for high-level intruder detection.
