How to solve the problem that infrared cameras often fog

Infrared cameras often encounter fogging during use, so how do infrared cameras often fog? At present, the infrared machine is not easy to fog. In the face of such problems, our engineering merchants will have a headache. They will receive calls from customers in two days. What kind of machines do you have? In a few days, it is blurred. Some machines, even those that fog at normal temperature, often fog. The solution is: 1. Improve the current of the main board, 2. Keep the machine dry.

In fact, fogging is also related to the lens. In order to reduce costs, some manufacturers purchase some cheap raw materials. For the current market products, there are conservative estimates of 50% of unqualified products. In fact, everyone is talking about "fogging", most of them are not water vapor. Think about the heat of the LED board. Generally, the heater for defogging is not hot, and the water vapor has been evaporated. It looks like fog, for several reasons:

1. The lens hood is leaking light and is not in close contact with the glass. The infrared light is refracted into the lens, especially 4mm is the most serious;

2, the parameters of the machine board itself is wrong, if you just use the general machine board to change the filter to use it, there will be problems, white, but still ok during the day;

3, the old problem: overheating, CCD white bottom up, it seems to be white fog;

The water mist is mainly waterproof, and the air is humid. The heat generated by the infrared lamp and the CCD plate will cause water mist. The fog should be caused by the rapid rise of the humidity inside the camera in the temperature of the camera. The big time is the most serious.
