DPS is a dual technology system that uses a combination of GPS/PPS and RFC detection systems.
This creates an extremely stable, high security system, suitable for the most demanding applications.
RFC uses two coaxial cables, buried in parallel 25 to 30 cms deep and 1 to 1.5 metres apart around the perimeter.
One cable transmits a radio signal that is detected by the other. Changes in the received signal, caused by an intruder can be detected and analysed.
The latest version, CHAIN, can provide variable length, programmable detection zones, identifying the point of intrusion to within a few metres
