I have been on plenty of prewires that have cat 5 running all over the
place. It was not cost effective to replace all the cables, so I
installed a 24VAC camera power supply, and put a full wave bridge
rectifier at each camera. I replaced all the fuses in 24VAC supply in
favor of auto resettable fuses. It is a little extra work, but this
actually gives you more flexibility. I also installed resettable fuses
after the rectifier.
