A perimeter-protection system created by a team from the USC Viterbi School of Engineering took Best Paper prize at the IEEE Homeland Security Conference in November 2010, and is now moving to deployment at a Florida airport, while also being considered for further installations by the Transportation Security Administration. This smart sensor system recognizes spatio-temporal sensor patterns of perimeter intrusion by foot, by fence, and by vehicle for the purpose of protecting remote fenced or virtual perimeters against unauthorized access or terrorist attack on TSA airport property. The system’s novel approach allows target intrusion sounds to be identified by users with specific needs. For example, at airports, the sensors were trained to ignore typical fence manipulation (kicking, leaning, shaking) by visitors who gather at end-of-runway fence lines and watch landings and take-offs. However, the system actively raises alerts if the fence is climbed or if someone attempts to breach the perimeter. In turn, the ground sensors ignore the presence of large jets, but raise alerts for human footsteps in unauthorized areas and can be programmed to either raise alerts or to simply report the presence of vehicles in certain protected areas.
