SEISMIC PERIMETER INTRUSION DETECTION SYSTEM

摘要

An intrusion detection system including a plurality of extremely sensitive seismic sensors, distributed with a relatively high density in a strip along the perimeter of a protected facility. The high sensitivity and high density of the sensors are used to recognize impacts caused by human footsteps, and time-domain clustering of impacts is used to recognize human footsteps and triangulate the position of an intruder.
