A video surveillance system includes one or more cameras communicatively coupled to a control system via a dual use medium. The video surveillance system includes a setup mode, a live viewing mode, a record mode, and a search/playback mode, some of which may operate simultaneously. In a live viewing mode, a user can view video data from one or more cameras using a graphical user interface. In the record mode, a user can independently set the record modes and schedules of the cameras, specify multiple motion detection zones per camera, and record in panic mode. In the search/playback mode, a user can search for and view, previously recorded video segments and perform file operations on the recorded video segments.
