ok , here is the question. Rather than run another cat5e cable to my attic which will be a pain, i would lke to utilize an existing cat 3 cable.
The camera is an older hcm-531 poe (802.3af) low res 640x480 ptz. The cable run is 150 feet. I thought I would just hook uo the 3 pairs into an RJ45 connector and plug it into a POE switch.
From what I read, over this distance it should work.
Has anyone of you more experienced installers rigged an older cam this way and what pair on the jack would I ignore?
Thanks,
HM
