David Swanson from Penn State University has developed a security system called APIDS – acoustic perimeter intrusion detection system. The system uses wires connected to geophones. When the wires are disturbed, the vibrations in the wires are analyzed by a computer to determine if the vibration is caused by an intruder or a false alarm such as wind, rain drops or a bird sitting on the wire. <\/p>\n
