Night watch

Night vision systems play a crucial role in the safety of driving in the dark; drivers can be alerted to people and animals ahead of them with passive far infrared technology. Night vision systems generate an alert well in advance of a collision and help the driver to completely avoid a dangerous situation. The two types of night vision technology are active near infrared (ANI) and passive far infrared (PFI). ANI systems feature an infrared light source that is integrated into the headlights. However, current ANI systems can have difficulty distinguishing between objects, people and animals. PFI systems detect thermal radiation emitted by objects in the field of view and are not affected by glare from oncoming traffic. A discussion of the technology is presented in this article. The Japan New Car Assessment Program (NCAP) and Euro NCAP have started taking these systems into consideration.
