Haze weather, a lot of outdoor activities will be affected, the operation of all walks of life are also more or less affected, especially the traffic sector, when the haze is severe, visibility is very low, affecting the operation of traffic vehicles, and even lead to traffic accidents, highway closure, flight delays and even canceled. Haze weather, led by visible light traffic monitoring system appears helpless, powerless. The working wavelength of ordinary visible light cameras is between 380 and 780 nanometers, which is far less than 2.5 microns. The visible light reflected by objects is blocked by PM2.5 and cannot reach the camera, which makes visible light cameras unable to be used in haze weather. Therefore, how to solve the problem of low visibility caused by haze has become the focus of people's attention nowadays. Infrared thermal camera with a wavelength of 8-14um can solve this problem. The principle of infrared thermal imaging is to receive the infrared radiation energy of the detected object, and then convert it into infrared images that can be seen by our naked eyes. It is little affected by weather and light, will not be affected by PM2.5, and can produce clear images. Based on this advantage, infrared thermal camera can be an excellent device for monitoring and driving assistance in haze weather. In fog and haze weather, visible light has no penetrating function, while infrared thermal camera is not affected by weather conditions and visible light, and can clearly penetrate rain, snow, fog and haze and other severe weather conditions.

The smoke penetrating function of infrared thermal camera can be mainly applied in the following fields:

1. Night security monitoring

Security monitoring is mainly using visible light camera, if visible light at night to monitor the function of the equipment will be discounted, if fill in the form of light using artificial lighting, exposure to the target, then the infrared thermal camera can have very good effect, the infrared thermal camera is passive to accept target infrared thermal radiation, it is not affected by light conditions, day or night can work normally and not expose themselves. Similarly, in fog and haze weather, visible light is difficult to find targets, while infrared thermal imaging device can. In haze and other severe weather conditions, infrared thermal imaging device can make up for the shortage of visible light and realize 24-hour real-time monitoring, no matter whether there is haze or not in the day and night.

2. Vehicle fog penetration, night vision

Traffic accidents caused by poor visibility in haze weather are common in real life. Infrared thermal camera can be as auxiliary driving system, help the driver in low visibility is clear that observes the information of the vehicle in front or the dark, not to also can see cars headlamps irradiation area, light the shadow of the pedestrian, vehicle, a significant reduction in the night, smoke and fog weather the dangers of driving, thus reducing the risk of traffic accidents.

3. Forest fire prevention and control

Forest fires and other unexpected disasters happen from time to time, and most of these disasters are caused by obscure fires. If we can find these hidden fires, accurately judge the location of the fire and find the ignition point through smoke, so that we can prevent and extinguish them early and reduce many unnecessary losses. The forest fire prevention monitoring system based on infrared thermal camera can realize the following idea: the thermal camera detects forest fire hidden danger through smoke, and the linkage alarm system alarms and assists in positioning, notifies and helps the staff to find the specific fire hidden danger location, and promptly nips the fire in the bud.

4. The police use the night to investigate

Infrared thermal camera can help police officers stay up all night looking for missing people or fugitives. People are strong radiators of heat, and their positions are easily determined by thermal cameras. The use of thermal camera can also detect people hiding in concealment.

5. Inspect the exterior wall of the building through fog

It is difficult to see the outline of the building in the haze day, and the infrared thermal camera can see the building through the haze, so as to carry out building repair and inspection.
