System senses and analyses the vibrations and the movements of a fence while an intrusion attempt for cutting (also performed by means of hacksaws or angle grinders), breaking through or climbing is occurring, discriminating all those noises which could trigger improper alarms. The detectors employ two different sensitive elements: a well-proven PIEZOELECTRIC transducer and a MEMS accelerometer.

The system can discriminate the passing of small sized animals from real intrusion events. Thanks to their robustness and the absence of active electronic components, the sensors do not need any planned maintenance.

Advanced intrusion detection system creating an invisible and unidentifiable detection band around the area or the building to be protected. The system uses special sensors which perceive the movement waves generated by a person crossing the protected perimeter.
