STI-103 Buried Seismic Intrusion Detection System

Safeguards Technology, Inc.
Safeguards Technology's Geophonic Seismic Intrusion Detection Systems are placed in or on earth, asphalt or concrete to detect low-level intruder vibrations. These signals are processed and analyzed to selectively discriminate between actual intruders and natural disturbances. The STI-103 offers a reliable and cost-effective solution for a number of different terrain situations. Seismic systems are ideal for protecting utilities, military sites, prisons, refineries, estates, residential, industrial sites or sensitive land areas.
The seismic signal processors compare signals generated by the geophones to a user adjustable threshold. As each signal crosses this threshold, it is scanned for timing, count and other criteria. It also compares detector line inputs to discriminator line inputs to filter out ambient disturbances. When all criteria are met, the logic system generates an alarm condition.
