A method and apparatus for controlling a video surveillance system are disclosed. The video surveillance system includes a plurality of video cameras producing a first plurality of video signals. A video switcher selects a plurality of video signals from the first plurality of video signals. A video splitter selects a subset of the plurality of video signals and forms a composite video signal which is fed into an overlay circuit. A computer generates graphical information which is overlaid onto the composite video signal. The composite video signal and the overlaid information are displayed on a monitor. An input device is provided to permit the graphical information to be manipulated on the monitor, thereby controlling the cameras, the video switcher or the video splitter. Control data is communicated from the computer to the cameras, switcher and splitter by means of a data bus.
