do not use an infrared light source, instead they capture thermal radiation already emitted by the objects, using a thermographic camera. Pros: greater range of about 300 meters or 1,000 feet, higher contrast for living objects Cons: grainy, lower resolution image, works poorly in warmer weather conditions, larger sensor Audi Night Vision Assistant was introduced in 2010 on the Audi A8. It uses a thermal imaging camera behind the four rings at the front of the car which can "see" 300 meters (984 ft) ahead. The display in the instrument cluster highlights humans with yellow markings. More importantly, the computer can determine if the person on the road moves in a way that could lead to a collision with the car. In that case the pedestrian is being marked in red color and the driver of the car receives an audible warning. 2013 update added animal detection. and Pedestrian Marker Lights: As soon as a pedestrian is detected by the Night Vision Assistant in a critical range in front of the vehicle, individual Matrix LEDs flash briefly 3 times in succession to alert that person, who is then clearly visible to the driver. BMW BMW Night Vision introduced in 2005 on the BMW 7 Series (E65). This system processes far infrared radiation, which minimizes non-essential information placing a greater emphasis on pedestrians and animals, allows for a range of 300 meters or nearly 1,000 feet, and avoids "dazzle" from headlights, road lights and similar intense light sources. 2008 update added pedestrian detection system on the redesigned BMW 7 Series (F01), which flashes a caution symbol on the navigation/information screen and automotive head-up display when it detects pedestrians. 2013 update added Dynamic Light Spot. 2013 update added animal detection. The system provides a real-time video image that also depicts on the Control Display persons, animals and other objects emitting heat when they are outside of the light beam and warns in the event of an impending collision. The Dynamic Light Spot is produced by a special headlight that directs the light beam onto the recognised persons or animals respectively, thus drawing the driver’s attention to possible hazards in good time. As soon as the remote infrared detects pedestrians or larger animals on course for collision in the dark, the system directs two separately controlled Dynamic Light Spots at them without creating an unpleasant glare. In the event of an acute risk,
