I have created a water proof housing with a cheapy wooden birdhouse and added a clear camera UV lens filter as the window. I am getting a lot of distortion sorta like a wide angle lens.
Please excuse the crappy hotglue job. New gun just spews glue.
My WAG is the microphone is “covered” - can you put a spacer under the camera to lift it up a bit? (it may add also be an “echo effect”)
You do know if the IR light is used, it’s gonna reflect on the lens and “bounce back into” the camera
Can you post a picture of what the camera sees?
I changed the height of camera and the images got better. Also, the cam in question has a yellow filter as window. Its night vision is way better than the other cam that has just a clear filter.
The IR lights are causing that reflection in the second pic. Maybe try disabling the IR lights and leaving night vision on auto.
Your second photo - that’s what I was referring to in my first reply.
