If you look at certain Dometic cameras, you'll notice LEDs surrounding the lens. These LEDs transmit a light that is invisible to the human eye: infrared light. There are other ways to create night vision, but the beauty of infrared is its ability to capture footage at high speed and its eliminating of variables in ambient light. Most night vision cameras apply a monochrome filter because black and white are the easiest colours for the human eye to differentiate. It certainly makes a handy tool for driving in the dark!
The Dometic PerfectView CAM 45 NAV is a small colour camera with silver housing for nearly invisible guidance of cable. Recommended for all leisure vehicles, it comes with all important features as microphone, temperature-controlled heater or separate IR-LEDs for optimal night-time vision.
