ABSTRACT:
A dual-modality sensor for detecting a presence of a human intruder within a secure setting includes a seismic sensor for acquiring a seismic signature of a disturbance, and includes an active acoustic sensor to acquire an acoustic signature of the disturbance. A system processor is electrically connected to the seismic and active acoustic sensors to receive and process the seismic and acoustic signatures, and generate an alarm signal when the disturbance is determined to come from a human intruder. Also included is an antenna and/or hard-wire connection arranged for communicating the alarm signal. The dual-modality sensor is arranged in a sensor housing constructed to contact a surface of the secure setting. The sensor may include a battery or other means for providing electrical power.
