SISMA CP50

SISMA CP 50 is compatible with several types of surfaces without concrete foundations, such as the ones covered with grass, gravel, tarmac and interlockings. It creates an invisible and unidentifiable detection band which, depending on the cases, can protect the whole perimeter of a site or specific driveways or walkways.
The system employs special geoseismic sensors which perceive the seismic waves generated in the groud by a person walking on the surface. The detectors are prewired on two different communication channels in an alternate way, so that an intruder generates a signal on both of the channels at the same time. In this way the analysis unit, to which the signals are sent, is provided with a “double acknowledgement” (AND detection) to effectively discriminate environmental nuisances from real intrusion events.
