The Camera is a block-type object in the game world.
It can spot you in the night while walking around, causing 25-30 Heat.
If it has spotted you the green light on the front will turn to a red one. Once spotted it will cause further Heat every 3-5 seconds.
The camera doesn't seem to alert guards until you reach the pursuit Heat level (90-80).
You can slip through by walking close to the wall, but stopping beneath a camera will still get you spotted.
Doesn't work while the Generator is off.
