What should I do if the infrared camera flickers?

The current ordinary infrared cameras generally use photosensitive elements to detect the lighting intensity of the environment, and generate control signals according to the threshold determined in the design parameters to realize the turning on of the infrared light. So when we are using the infrared camera, we may encounter the situation of the infrared camera image flickering, how to solve the flickering problem?

1. Change the threshold value: The threshold value is different for the same model product, and there is dispersion, and the problem may be solved by replacing one product.

2. The circuit design is unreasonable: In the production of infrared cameras, it is not only necessary to install the infrared light directly into the camera, but also to redesign and aging the camera circuit before installation.

3. Particles are captured: when there is a lot of dust outdoors, especially in the field, the infrared light of the camera may capture the small particles that are invisible to the naked eye. This is when the infrared light is not turned on during the day. , It is not obvious to the naked eye and the camera, this is the environment.

4. Handicraft issues: When many people are working, the infrared light is not concentrated and astigmatism. The scattered light causes light everywhere, but a grayish phenomenon. The cotton at the front end of the infrared lamp is not tightly blocked, and the concentrated infrared red scattered light is therefore a vague phenomenon.

The main reason for the flicker of the infrared camera is that the light-sensitive element detects that the illumination intensity is slightly lower than the threshold, and the infrared light is controlled to turn on the light-after the infrared light is illuminated, the detected illuminance is increased (plus the reverse infrared light) , And the threshold is exceeded, the infrared light is controlled to turn off ---- resulting in a decrease in the detected illuminance, and the infrared light is controlled to turn on again. Such a reciprocating motion causes the image to flicker. So the solution has been popularized by everyone, I believe everyone will understand after reading the above content.
