Thermal imaging night vision devices can produce realistic and clear thermal images in total darkness, mist and smoke. They can be seamlessly connected with widescreen navigation systems and multi-function navigation systems. The camera lens can freely rotate 360 degrees horizontally and pitch ±90 degrees up and down, allowing you to experience the sensory enjoyment and safety brought by military technology. 

Designed to enhance the driver's visual ability. The system can output clear thermal images of the road conditions ahead in total darkness, bad weather such as haze, and low human visibility such as glare from headlights, effectively improving the driver's visual range. 

At the same time, pedestrian recognition and front vehicle collision alarm functions can detect pedestrians, vehicles and obstacles in advance, greatly improving driving safety. 

Principle of thermal imaging night vision devices:

Thermal imaging is passive infrared, which relies on receiving infrared rays emitted by the temperature (heat energy) of an object, and then processed into an image for display. Generally, images are gray-white images regardless of day or night.

Thermal imaging is not active infrared. Thermal imaging night vision devices do not emit infrared rays themselves, but only receive infrared rays from the outside world. Therefore, it is very simple to conclude that as long as thermal imaging can receive infrared rays emitted by objects, images will be output. On the contrary, if infrared rays cannot be received, the images of the objects we want to see cannot be reflected.

Now, some of the questions we all ask, such as whether thermal imaging can see through, penetrate walls, see people and objects in the car, and penetrate glass, have certain results.

If it penetrates walls and glass, the wall blocks the infrared rays, and the thermal imaging night vision device cannot receive infrared rays at all, and cannot detect objects on the other side of the wall and glass. That is to say, if there is an image, there must not be a completely sealed object that blocks all infrared rays, otherwise it will definitely not receive infrared imaging.

In environments such as some trees and grass, since the infrared rays are not completely blocked, thermal imaging can still find objects with higher temperatures than plants behind them. For example, if there are people and animals behind the grass and trees, there is obviously a temperature difference. Things with high temperatures will be bright, and objects with low temperatures will be dark. 

Thermal imaging is actually temperature difference imaging. The infrared emitted by objects with higher temperatures is stronger, and the infrared emitted by objects with lower temperatures is relatively weaker. 

When a person walks behind the glass, the image of the person cannot be seen. That is because the glass blocks the infrared rays of the person outside. The thermal imaging night vision device cannot receive the infrared rays, so it cannot show that there are people in the image. 

Two people are standing inside. There are people in the image and on the glass. That is because the infrared rays of the person are received by the thermal imaging device. In addition, there are people on the glass because the infrared rays of the person are emitted in all directions, and the infrared rays emitted to the glass are reflected back by the glass and received by the thermal imaging night vision device, so we can see the image of the person on the glass. 

When a person wears clothes, most of the infrared rays are blocked by the clothes. The body part is darker because the temperature of the clothes is much lower than that of the head. The head with high temperature is brighter, and the clothes with low temperature are darker.

At this time, someone puts two palms against the clothes for 2 seconds. We find that there are two palm prints on the clothes. That is, the temperature of the palms is transmitted to the clothes. After the palm temperature is slowly removed, the palm prints disappear after 2 or 3 seconds. That is, the temperature of the palms on the clothes slowly dissipates and disappears.
