The wired connection has four wires: two + - of 5V and one is video and one is audio both way (duplex).
I have wifi at room and a wifi extender at the door end. So if I use two esp at both end and connect the esp ports with video and audio wires will that be fine. Also, will there be different programming for video streaming and audio duplex?
Please suggest for any other options and also if any ready made device can be used.
