Spyhole camera

Hi im looking for a spyhole camera that looks mostly like a normal doorspy and not obviously like a camera from the outside. Inside the door i would not mind a little box for a battery.

I want to be able to see a live stream or at least an image in homeassistant when somebody rings at my door (triggered by an automation). Also an included motion sensor would be nice (but low priority).

Everything should run local (no cloud connection).

Is there any product on the market?

Thanks for your help
