In simpler words, smart surveillance means to monitor maximum areas with the use of minimal cameras and recorders. This gives an exact idea of exactly what is happening at the place. The most common method of keeping an eye is the installation of CCTV cameras with a storage backup of several months. Cameras can be installed at crossroads so that traffic management becomes easier, at hospitals for keeping eye on the patient and other important places. These clusters of cameras are managed by a single place by few individuals.
