PPS Plus Buried Perimeter Intrusion Detection System with Crossing Point Identification

PPS Plus is a high security buried perimeter intrusion detection system that allows the crossing point of the intruder to be determined to within +/- 5 metres. PPS Plus uses underground sensing tubes which are completely invisible once installed. Filled with liquid and then pressurised, the tubes will detect the differential change in pressure between them, caused by an intruders approach. The system works under virtually under surface and can follow the contours of the perimeter
