I am not sure how you are thinking of building it. I am thinking you would need a server hosted somewhere that can send a doorbell or video to your phone? It needs security, server to phone push ... it gets complicated.
Doorbell send video to server on my desktop. Or wherever, I'll trade server space with a friend or something.
Id probably use an esp32 board so: The software to view it live is already written. The software to automatically send it is, I think, already written; just need to configure desktop. The motion trigger is already written.
Why would you need any software, server or phone for a simple door bell?
Ring and a bunch of these devices are convenience machines. The doorbell itself at minimum has a microcontroller, camera and mic with WiFi access, the server controls the doorbell, stores footage and makes live feeds available over the Internet for when you are away from home, a phone app lets you see who is at the door and let them in even when you're not home.
For anyone interested, a self-hosted home assistant will get you 80% of the way there, depending on how paranoid you are you can also set up POE cams and frigate.
Or just have a pot someone can bang really loud that works too.
Thank you. So it's not just a doorbell, rather a remote controlled surveillance and communication system. That is a bit more complicated than a bell at the door.
