night vision cameras

[dollyrocker]

are the night vision cameras actually state of the art infared cameras, or just normal cameras with the brightness and contrast settings up?

[LargeAndInCharge]

well could be both.

Not sure but I found this: Wikipedia (http://en.wikipedia.org/wiki/Night_vision)

i think they just put a few dim lights on in the bedroom, then inhance the brightness and contrast in the cameras. then make the colour b&w or green
