Abstract

A digital surveillance system in which the output signal of the camera is highly compressed, to the extent that the compressed signal can be sent over relatively low bandwidth wireless networks, such as cellular networks. The compressed signal is then uploaded to the wireless network from where it can be relayed to a server, such as an internet server, from where it can be accessed, viewed, manipulated and further used by authorized personnel. Such authorized personnel need not be proximate to the surveillance equipment at all. The digital surveillance system can include fixed cameras mounted in fixed orientations and the signals of the various fixed cameras can be integrated into a wide view, as well as used as individual narrow views. These views are wirelessly communicated to an internet server from where they can be accessed, viewed, manipulated and further used by authorized personnel. To power the cameras and the wireless communication device, one or more solar panels are mounted on or applied to the fixed camera mount.
