【Problem phenomenon】
The infrared effect is blurred, and some areas around are white, making it difficult to see distant objects. As shown below

【problem causes】
1. The whole or entire area of the screen appears white, mainly caused by the direct reflection of infrared light from nearby objects.
2. The picture is dark, it may be because the scene is empty and the shooting angle is too high, which makes it difficult for infrared to reflect effectively

【Corresponding solution】
1. Check whether there are reflective objects near the camera.
2. Lower the camera lens to allow the infrared light to reflect effectively.
