Drillers of drilling rigs and workover rigs can watch monitored areas directly through cameras, and the video can be transmitted to the monitoring center. Any channel can be monitored, with single-window display and switching display of up to 9 windows; monitoring and screen-switching control are supported. The display can generally be split into 1-9 windows in any combination, and a single window can be switched to full screen. Brightness, contrast, color and saturation can be adjusted for each channel. Images captured by cameras installed at various positions of the wellsite are transmitted to the wellsite local network. The driller-cabin controller and monitors can browse and control the images and cameras of key areas in real time.
