I have a Pi connected to a peep-hole camera that is mounted in my door to see who is outside.
I found the camera on AliExpress and it need an USB video adapter to work but what I do not like about it is the low quality. I have tried to find something better but failed.
Is there a way to use the Pi's camera module, in a good way, to see who is on the other side of a 50 mm (2 inches) thick door?
The problem seem to be a combination of 50 mm thick door and fish eye lens.
I live in a rented apartment so I cannot start cutting up the door.
I talked to someone at waveshare.com, which have some stuff like that, but they could not help me.
