RF volumetric intrusion detection device, system and method

摘要

A device, system and method for the detection of intrusion using radio frequency (RF) signals are provided. The system comprises at least two devices. The system detects intrusion by measuring the Received Signal Strength (RSS) of a RF signal sent by the first device to the second device via a RF channel. The RF signal receiving device determines if the variation of the current RSS value is due to an intrusion in the RF channel or not an acts appropriately.
