Abstract

A satellite surveillance system and method of using comprising at least one analog video camera for recording a video stream in a remote location; an encoder connected to the analog video camera to convert the video stream to digital video information; a device to detect an anomaly in the vicinity of the analog video camera, a remote VSAT terminal connected to the encoder to transmit the digital video stream from the remote location to a satellite based on detection of an anomaly by the device to detect an anomaly; wherein the digital video stream is transmitted based on an algorithm to process bandwidth requests from the remote terminal; and a hub processing center for receiving the digital video information, wherein digital video information may be received from a plurality of digital video streams from different remote locations.

Claims
