We want a new door bell and we will even be able to run new wires (currently we only have 2 Wires). I would like to have video and 2 way audio locally hosted, though the most important thing is, that the base functionality (door bell button with connected wireless door chimes through the house) needs to be absolutely reliable (no random connectivity issues).

I have found the Acuvox R20A, which is seems to have all the bells and whistles about SIP (audio and video) calls. Though from its documentation it seems, that bell chimes also must use SIP, making it more depending on my network infrastructure and the self hosted SIP server (like Asterisk). I don’t see a possibility to trigger a relay on button press for triggering traditional door chimes. Which is a shame, since that would be the most reliable for this basic functionality

Do you have good ideas on how to go with this? Or does it make sense, to break this up and use a more basic door bell, while also adding camera and audio additionally as separate devices?
