hi, it's supposed to be a cam control, so you can both see what the cameras see and you can also turn them off while you stand there. Cameras themselves have a little light to indicate whether they are on or off. Happy burglerin'!
But how would you turn off the cameras as you are there, is it like the green thing is the monitor selection and if you press up it turns of the camera? And if its black its off?
that is exactly right! but you can only turn off one camera at the time, and if you happen to select it again it will become active again. You can disable the camera of you go up to it with burglar nr 2 ;)
