The collective term for night vision in the automotive industry encompasses a number of loosely related technologies that can help increase situational awareness when it is difficult to see the road in low light.
Automotive NIGHT VISION – Don't buy until you see this
These systems use thermographic cameras, infrared lights and heads-up displays to extend driver perception beyond the limited range of headlights. By alerting drivers to otherwise invisible hazards, automotive night vision can help prevent accidents.
There are two categories of automotive night vision: passive and active. Passive systems use thermal cameras to illuminate the heat radiating from objects, animals and people. Active systems use infrared light sources to illuminate darkness.
Both active and passive night vision systems rely on the infrared light spectrum that is invisible to the naked eye. They each have their own advantages and disadvantages.
