Many customers contact us to complain that the camera's daytime vision is OK but night vision faces issue like picture below. Half image is too dark while half is too white.
This problem is caused by the wrong position of camera's head place.
Camera's lens can not be point close to object like wall. Otherwhise, the red infrared lights will reflect to object and affect the night vision like above picture.
It is not our camera's problem. Not only ours but also all cameras in the market face the same situation.
The solution to prevent this issue is to move camera away from the object to make sure there is nothing cloer to lens so that its image will be normal.
