Car night vision system worksystems are sensors or devices that detect and respond to some kinds of input from the physical surroundings. The specific input could be pressure, moisture, heat, motion, light or any type of environmental phenomena. Also called automotive night vision systems, these devices can make you well informed about vehicles, animals or people that cannot be immediately seen by your headlights in low light situations.
How does car night vision system work?
When light is not sufficient for you to see the road, night vision systems can help you increase your perception of environmental elements through the use of technologies such as thermographic or heat sensitive cameras or infrared lights. These car night vision systems can help you avoid accidents during the night and when the weather makes it difficult for you to see what's ahead. They will inform you of possible hazards before your headlights can.
The choice of night vision systems for cars are mainly made available left to be chosen by the discretion of car buyers, so as to what type they needn't would like be installed compulsorily in their cars, hence they are not necessarily installed by the car manufacturers.You have to choose to have get it done to for your car or buy it separately and install place it in position by yourself.
Categories of car night vision systems
Night vision systems in automobiles come to you in two categories: the (1) active NVS, and (2) passive NVS. Let us see how they differ from each other:
- Active night vision system
This is a more complex system than the passive NVS, as it uses near-infrared light sources, which illuminate the road situation that is remarkably farther away than what your headlights can reach. This system will also not cause you temporary night blindness like when you come across high beam headlights.
Infrared lights are not seen by the naked eyes, so to relay the visual data, night vision systems use special cameras that pick up even the slightest or smallest traces of light and make a complete change in the appearance of the illuminated object. These systems will not perform well, when there's smog or heavy fog and other bad weather conditions, as it'll block the infrared light source partially. However, active night vision systems can give you high contrast images of animals, vehicles and inanimate objects.
Active night vision systems are offered in luxury models of brand such as Toyota, Mercedes and Toyota. The good news is that there is also another car night vision system that is becoming popular in the automobile market and that is called the Lanmodo Vast. This system offers you safer driving in situations that are not driver-friendly.
This night vision system from Lanmodo offers a full color image for better visual effects and also includes a 1080P full HD resolution. The 8.2 IPS screen is not hurtful to the eyes. You also get a wider view of the road ahead because of the 36°wide-angle vision, with a night distance of about 300 feet. The Lanmodo Vast Night Vision System can be used in most car models, unlike the built-in NVS that are applicable only on specific models.
Another positive feature of the Lanmodo Vast is that it can be easily installed even by yourself and you do not need to take the car to a motor shop to have the night vision system placed in position. In addition to that, the price of Lanmodo Vast is way, way cheaper than the other systems. You can save about $2000 when you choose the Lanmodo over built-in night vision systems.
- Passive Night Vision System
In Passive NVS, images are registered based on body heat and the representations produced are like those of the photo negatives. Although it works well for decoding between animals and people, this system doesn't serve much in showing a fallen tree, a big rock or a dead animal in the center of the road.Passive car NVS system uses sensors that pick up heat from objects and then have them processed to display on the screen mounted on the dash in the middle point of the console of the vehicle.
Passive car NVS system uses sensors that pick up heat from objects and then have them processed to display on the screen mounted on the dash in the middle point of the console of the vehicle.To put it in the fewest possible words, passive infrared system picks up the heat of the pedestrian or an animal and have it displayed as a bright image. Take note that the warmer the target, the brighter the image on display. The passive NVS can very well illuminate what's ahead of the car, but it does not provide the clarity that you can find in the active NVS. Passive automotive night vision systems are offered by Honda, BMW and Audi. The Cadillac by GM also offered passive NVS, but it was stopped in 2004.
Many studies have proved that accidents mostly occur at night and at places where there is not sufficient light. Technologies such as car night vision systems can definitely reduce the occurrence of these accidents. As mentioned above, a Lanmodo Vast Night Vision System can provide safer driving, with better features as compared to built-in systems and when used properly can help you avoid possible collisions.
