My door bell stopped working over the weekend, so I figured I’d build a new one rather than pop down to buntings for one!
My old bell had a push button at the door and a CAT 5 cable between it and my structured cabling, at the end of that was an 8V power supply.
I have plenty of space in the wall for a PZW plus camera but have no power so it will need to be sent via the CAT6 cable. The power supply could be about 6m away from the PZW. I’m thinking that I could use a standard Pi power supply, chop off the micro USB end and solder the wires to a pair of the CAT6 cable and then solder a new plug on the other end, about 6m away.
I’m somewhat concerned about voltage drop.
I guess I could use two pairs of the CAT6 rather than one if that would help.
