ESP32-based visual smart doorbell reference

You surely know the feeling when the doorbell rings while you are doing something fun: watching a movie, playing video games or having a romantic evening with your loved one. You are even more annoyed when it turns out to be an uninvited/unwelcome guest. Of course, we can also ignore it and not open the door, but there will always be this hint of uncertainty - "maybe this is important". The solution to this problem is the "smart doorbell". Thanks to it, you will know if it is worth getting up from the sofa to open the door. My project is based on ESP32. It is a very popular module, so it is very versatile. It has Bluetooth and WiFi, so it can be connected to most home automation systems. The project also has a second PCB. It acts as a capacitive button. Thus, all the electronics can be enclosed in a sealed housing. Thanks to this, it will be more resistant to weather conditions. 3D housing: The housing is printed on a 3D printer. And the front panel is made of 3mm plexiglass. Painted black on the bottom with a normal spray. I left only the window for the camera and the backlight for the capacitive button. But the front panel can also be printed if resistors are not needed.
