ABSTRACT:
A video surveillance system includes a central control station and a plurality of video cameras each mounted inside a dome housing unit. A video data buffer memory, storing compressed video data generated by the camera, is mounted with each camera in the respective dome unit. Data buffered at the dome units may be selectively protected from over-writing in response to alarm signals and then retrieved for display or tape-recording by the central control station. Both live and buffered video signals are transmitted in compressed form over a data network that is also used for command, alarm and status messaging.
