"Haze" in Night Vision - Is This Normal?

I have a Wyze Cam which has a great picture during the day, but at night, it has a strange “haze” in nearly the entire picture, other than the middle. The middle is darker and clear.

I have two other cameras in similar setups without this issue, but the closest object in this setup is much further than in the others… Could it be the vehicles? Any thoughts?

It might just be the distance at which you are trying to get the IR LEDs to illuminate. Try putting two of the cameras side by side to test. If one is clearly inferior to the other in that situation, file a support ticket to get the bad one replaced.
