Night vision can work in two different ways. In the first case, the camera has wide lens to collect as much light as possible. As the light enters the cameras, it passes through series of filters, intensifying the light so that the scene can be clearly visualized. Other night vision security cameras can use infrared or thermal signatures to record scene. The advantage of this type of security camera is that it can see through smoke, fog, and other visual disturbances, although thermal and infrared imaging tends to be more costly.
