I'm looking into adding a video doorbell and some security cameras and want to integrate with HA. I have some cameras that came with the house, but I don't think they will work. The system has been discontinued and I don't have the "base unit" that connects them. If there is a way to use them, I'd be happy to find out if they are operational and use them. Web search has not helped.

My first priority is a video doorbell. I don't really understand much about how it works, and there is a lot of conflicting information out there. I have a wired doorbell, and I could probably manage to figure out how to run a data line if needed.

I want it to play nicely with any future system. The current camera system is wired, and I'm happy to run new wires if needed. I have plenty of storage on my home PC server, and I'd prefer to use it.

Any guides out there that really cover the overall process?
