I'd like some advice about video doorbells please.
I already have a 12v supply to the bell push end and I would like to run a video doorbell system where I answer via a small monitor inside the house.
(I do NOT want a system that works via my smart phone as, apart from, anything else, the signal is poor.)
I am wondering of there is a set up that works using the 2-wire 12v system. I am happy to do further wiring indoors but not through the front wall!
I don't wish to have a battery powered system, a wi-fi system or remote unlocking.
Am I asking for the Moon or is there a video intercom system which runs on the 12v 2-wire set up?
I shall be grateful for any help, suggestions or advice you can give.
Thanks in advance

Voice intercoms use only two wires, video will probably require 4 wires. Does google show any 2 wire video intercoms?

Thanks Mr White,
I have looked at Google and there very few, usually in the £250+ price bracket!
Looks like I'm 'stuck' with audio only as I won't justify a price that high.
Thanks

That is what I thought, thanks for getting back though.
