This paper describes an unattended surveillance system that is used to monitor border crossings, remote airfields, choke points, and any other remote area not suitable for continuous human presence. The system employs intelligent acoustic/seismic unattended ground sensors, two-way radio communication, and a low light video camera. The acoustic/seismic sensors provide long-range target detection, target classification, and angular bearing to the target. The camera is cued by the acoustic/seismic sensors and takes a picture of the target for visual confirmation. All information, including the picture, is transmitted via radio to a monitoring post.
