System for detecting intrusion attempts comprising crash and/or vibration detection means built into the posts of a fence, and device to be installed on fence posts

摘要

The system has detection units (3) for detecting vibrations and shocks produced on a fence, where the fence comprises panels (2) fixed on poles (1). Transmission units transmit data issued from the detection units to a remote control station controlling a personal computer, where the detection units constituted by capacitive type accelerometers are carried by one of the poles. The transmission units are associated to data reception units receiving data by radiofrequency, and the detection units are integrated on a fixed card in a recess of one of the poles.
