Why is there a camera flashlight phenomenon ?

The reason is that the infrared camera\'s night vision function is to use an infrared lamp as a light source to obtain image information under dark conditions.

Flashlight phenomenon:

In some parts of the camera screen, the light is irradiated strongly, the emission angle of the infrared lamp is too narrow. Increasing the infrared lamp angle and reducing the lens angle can solve the problem.

Vignette phenomenon:

Feet are weaker somewhere around the screen, as if the light is blocked. The reflection of the infrared lamp may cause poor lens focusing. Using double glass to separate the lens and the infrared light source can solve the problem.
