The new developments can provide greater field of view, and will not let the reverse of the vehicle was dazzling. As a result of Night View Assist system, you can see the traffic signs in advance not shine lights the darkness of the past, corners, pedestrian, car, missing goods or other things can be dangerous on the road.

Principle

It is a night vision system invisible infrared converted into visible light. 0 degrees above absolute object must radiate energy. The lower the temperature, the longer the wavelength. When the temperature is generally as infrared. When the temperature is about 800 degrees, radiation to visible light, a red-hot iron is why one can see the light. Infrared is invisible, at night there is no visible light, but infrared radiation is still, at different temperatures and the surrounding trees, the radiation of infrared wavelengths are also different. Because infrared radiation is very weak, it is converted into visible light is weak.
