Abstract:
A video surveillance system includes a plurality of remote surveillance units, each of which has a video camera mounted in a dome housing. The video camera is panned and/or tilted to a desired orientation within the dome by a pan motor and/or a tilt motor. The surveillance system also includes a keyboard for entering user commands, a joystick for controlling the positioning of the cameras, a central processing unit for interpreting the user commands and the joystick movements, and a communication system for issuing operating commands to the remote surveillance units. Each remote surveillance unit is constructed and arranged to store and to recall selected camera control parameters in association with selected pan and tilt coordinates in response to commands entered by the user. The camera control parameters include white balance, focus, and shutter speed settings for the camera. Additionally, automatic control of the camera exposure, white balance, and focus is provided.
