Abstract
A video surveillance system having a plurality of video cameras and means for reproducing the scenes viewed by a selected by one of the cameras. A switch selectively connects the cameras to the reproducing means. A counter generates a sequence of signals wherein each signal corresponds to one of the cameras. The counter signals are applied to the switch to select the corresponding camera and apply its output to the reproducing means. The counter signals are also applied to a character generator which generates characters identifying the selected camera for display at a selected location in the reproduced scene.
Claims5
A video surveillance system comprising
- A. two or more video cameras, each camera generating a video signal corresponding to the scene viewed by that camera,
- B. means responsive to the video signals for reproducing the scenes viewed by the cameras,
- C. counter means for generating a sequence of counter signals, each signal corresponding to one of said video cameras,
- D. switching means connected between the cameras and the reproducing means for automatically applying the video signals from the cameras to the reproducing means in response to the counter signals for a selected time interval and in a selected sequence so that the reproducing means can reproduce the scenes viewed by said cameras during said time intervals and in said sequence,
- E. means for generating, in response to the counter signals, video signals representing the characters identifying the respective video cameras, and
- G. means whereby the reproducing means reproduce the camera identifying characters at a selected location in the reproduced scene.
