A surveillance system with the motion detection and the location measurement capability has been in development for the help of effective security control of facilities in our institute. The surveillance cameras and sensors placed around the facilities and the institute have the primary responsibility for preventing unwanted accesses to our institute, but there are some cases where additional temporary surveillance cameras are used for the subsidiary purposes. Problems in these additional surveillance cameras are the detection of such unwanted accesses and the determination of their respective locations. To eliminate such problems, we are constructing a surveillance camera system with motion detection and self-locating features based on a server-client scheme. A client, consisting of a network camera, wi-fi and GPS modules, acquires its location measured by use of GPS or the radio wave from surrounding wifi access points, then sends its location to a remote server along with the motion picture over the network. The server analyzes such information to detect the unwanted access and serves the status or alerts on a web-based interactive map for the easy access to such information. We report the current status of the development and expected applications of such self-locating system beyond this surveillance system.
