CCTV
A CCTV camera lets players in the game watch an area from a computer station. The camera has no settings of its own. Its camera ID, which players type into the computer station, is the Identifier in the RC Entity panel.
A CCTV camera is an IO entity: it needs 3 power. Wire it in the IO Entity panel, see IO wiring.
In Play mode you cannot watch a camera: there is no computer station to watch it from.
