So I was wondering if I could power my 8 or at least 4 ip cameras from my old pc psu.
I have: *500 W psu, where 12 V can use up to 360 W
*GV-EBL1100 ip cameras which require 12 VDC / (IEEE 802.3af), not sure if 7.4 or 15 W per camera (confused from documentation)
*non-PoE router I think (nWay switch)
I want to make a diy injector with at least 4 sockets which connect to ip cameras (data + power) and 4 sockets which go back to router with data only.
Is it possible to connect all 4 cameras CAT5 cable power pairs parallel to a single psu 12V power pair using DC-DC transformer to 48V?
Does this particular ip camera communicates to negotiate power supply over data cables?
Will it work if CAT5e cable is splitted the way that power goes to ip camera but blank to router via (unused?) pairs?
Or just buying the poe switch is the only option here?
Don't hesitate to ask if something is unclear, I don't know if I provided enough information and clearly.
Thanks in advance.
