Is car night vision useful?

In order to improve the safety of car driving, especially at night, some cars will be equipped with on-board night vision devices. It has an infrared detection system that can sense infrared rays beyond the visual range of the human eye, helping car owners to observe from a longer distance. It is quite useful to increase the sight distance, widen the field of vision, eliminate the interference of passing lights, and facilitate driving at night and in bad weather. There are many types of vehicle night vision devices, which can be divided into civil, police and military according to their uses, and can be divided into near-infrared technology, far-infrared technology and low-light technology according to technology. Let's take a look at the knowledge of car night vision devices.

1. Are car night vision devices useful?

Car night vision device is a kind of vehicle night vision device. It was used for tanks at the beginning of its invention. With the development of technology, there are civilian products, which are car night vision devices. Many cars have vehicle night vision devices, and their functions are mainly It is more useful to improve the safety factor of car driving at night. The main functions of car night vision are:

1. Increase the viewing distance and broaden the field of vision

Car night vision devices can help car owners see the range from 200 meters to 1,000 meters away, see the places where the lights cannot shine, expand the safe distance, and allow the car owner to have more room for braking and reaction to prevent potential dangers , such as pedestrians at night, temporary parking, etc.

2. Eliminate the interference of traffic lights

When meeting cars at night, in order to remind the other party, the oncoming cars usually have high and low beam lights alternately. Although it has a reminder effect, the high beam lights will also affect the car owner. , you can see your own lane.

3. Convenient for driving at night and in bad weather

At night and in bad weather conditions such as rain, snow, fog, etc., the field of vision of the headlights is limited, and the vehicle-mounted night vision device can help observe the target ahead and improve the safety of driving.

To sum up, car night vision is quite useful, especially for car drivers at night, as an active safety device, it can prevent problems before they happen and improve the safety of car driving.

2. What are the types of car night vision devices?

The car night vision device has an infrared detection system, which can sense infrared rays beyond the visual range of the human eye and help the owner to observe from a longer distance. There are many types of it, and there are different types according to different classification standards. Have:

1. According to the purpose

It can be divided into civilian vehicle night vision device, police vehicle vehicle night vision device and military vehicle vehicle night vision device.

2. By technology

(1) Near-infrared vehicle-mounted night vision device: CCD night vision device, with mature technology and good batch performance, but relatively low sensitivity, generally used in the civilian market.

(2) Far-infrared car night vision device: The car night vision device using TIS thermal imaging technology, also known as the car thermal imaging night vision device, can be observed through thick fog.

(3) Low-light vehicle-mounted night vision device: Adopting low-light TTI amplification technology, it is the mainstream of military vehicle-mounted night vision device.
