Multi-camera surveillance and monitoring system
First Claim
1. A multi-location video surveillance system comprising a plurality of video cameras adapted to be located at a corresponding plurality of locations, a plurality of video means respectively operatively connected to said plurality of cameras for respectively receiving video signals from said cameras and for respectively transmitting video signals respectively derived from said cameras to a remote television receiver, a plurality of control means respectively operatively connected to said plurality of video means and adapted to be operatively connected to a common ac power line, transceiver means operatively connected to said control means for transmitting a binary-coded control and select signal to said control means along said ac power line, each of said control means including an addressable control module having a unique address, said control means being effective in response to a received binary coded control and select signal that includes the address of the control means operatively connected to the one of said cameras that is then on to automatically turn off said on one of said cameras, said control and select signal further including the address of another previously off one of said cameras to turn on said previously off one of said cameras a predetermined time after said previously on one of said cameras is turned off, whereby only one of said cameras is on at any given time.

Abstract
A multi-location and multi-camera surveillance system includes cameras located at different locations. The cameras are selectively turned on and off by addressable control modules operatively connected to the cameras and a transceiver connected operatively to the modules, which turn off a previously on camera before turning another camera on, thereby to prevent more than one of the cameras from being on at any given time. The on-off actuation of the cameras may be achieved in a sequential fashion.
