, earliest type, dimmer knob can reduce brightness, display nearest to driver's line of sight There are two types of systems, either passive or active systems, both have advantages and disadvantages when compared to the other. The passive system pertains to the technologies that detect thermal radiation emitted by humans, animals, and other objects in the road while the active systems illuminate objects as a significant distance ahead using infrared light sources.

Toyota

In 2002 Toyota Night View was the first worldwide series production active automotive night vision system, introduced on the Toyota Landcruiser Cygnus or Lexus LX470. This system uses the headlight projectors emitting near infrared light aimed like the car's highbeam headlights and a CCD camera then captures that reflected radiation, this signal is then processed by computer which produces a black-and-white image which is projected on the lower section of the windshield. In February 2008 the Toyota Crown Hybrid added a feature which highlights pedestrians and presents them in a box on an LCD display in front of the driver. This was the first pedestrian detection feature for an active system. In 2009, Lexus introduced Night View on the LS, but only in Japan. In 2012

The Night View system combines a windshield mounted near infra-red camera and near infra-red projectors within the headlamps with a Night View ECU to display an image of the road ahead on center console display screen. Moving the image from the driver’s instrument display to the center console offers drivers a larger display and an easier viewing angle. With the camera constantly in operation and the near infra-red projectors activating at speeds over 10 MPH to enhance system efficiency, night view will display an area up to 65 feet in front of the vehicle. This system was discontinued for 2014 in the US.

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

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

, 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, an acoustic warning signal is also sounded and the brakes are set to maximum standby. For the model year 2014, the BMW 5 Series will also have these new features.

and worked by using a ''passive infrared'' sensor camera mounted behind the vehicle's grille. Infrared radiation is picked up by the sensor, processed by computer and then displayed on the windshield using a head-up display. Information is displayed as a black-and-white image with warmer objects in white, while cooler objects appear black. Because this system outputs a standard NTSC composite video signal and the used parts are somewhat easy and inexpensive to find, it has become a popular choice for fitting thermal night vision to other vehicles.

The night vision system uses a separate heads up type display projected on the center bottom of the windshield. The infrared cameras do not require a light source, and the software is able to detect human like figures, surround the image with a red box and give audible caution tones.

DS Automobiles

DS Night Vision offers road visibility by night. An infrared camera in the front grill identifies objects, pedestrians and animals on the road at a distance of up to 100m. A digital instrument cluster shows the driver the area around the car in infrared, with a yellow line around any sources of potential danger. For critical danger, the line becomes red, allowing the driver to react to the situation. The
