I have a Wyze Cam pro 3 camera and it is indoors facing out thru a window. At night I would get reflections from the indoor lights around the 4 corners of the screen.
My window has horizontal blinds and curtains.
The fix for the reflection was simple. Take a piece of paper as I did from my printer and cut a strip out that when you bend it and tape, will wrap around the camera.
Adjust so it is flush with the window.
No more reflections.
