           Control rooms for vital facilities are typically tightly secured and inaccessible to the general public. Multiple electronic displays and control panels (which are usually present), and there may also be a large wall-sized display area visible from all locations within the space, are the devices inside the Operations Control Center (OCC)  which are controlled by electricity. Some control rooms are themselves under continuous video surveillance and recording, for security and personnel accountability purposes.
