This is yet another cover for a Wyze security camera. The only differences are that I rounded off the side corners and only put in one hole.
"Where's the other hole," you ask? You don't need it. After looking at the main board inside, there is nothing behind the smaller, tinted, plastic circle. I tested covering it up and didn't notice anything change in the camera image in day or night.
Supports? Maybe. I had a better result with some support for the center of the circle.
