The idea of wide area surveillance (WAS) is to develop and utilize sensors which give continuous views of expansive areas. The traditional camera/optical/acoustic methods can only monitor small area, while the WAS system can monitor an area several thousand times larger. WAS is usually provided by airborne/satellite-borne cameras which cover a wide swath of area. It was primarily used in the US as military surveillance technology for safeguarding the homeland. WAS technology is slowly making its way from the battlefields into the Police/Coast Guard Departments in all countries.
