Need clarification here. Never having worked with one, I was under the impression that a POE splitter stripped the power out of the RJ45. Does it instead (as the name implies, duh) split the power off so you can power the cam through the RJ45 per usual and use the DC out to power a mic? 'Cause that would be perfect!
A poe splitter removes the power from the ethernet cable and has a data only rj-45 output jack. If someone uses a splitter, to power a camera and microphone they're doing that by splicing the 12v lines together.
The camera this thread is about and most PTZs use too much power for 802.3af and require 802.3at. For this PTZ you best options are:
-power camera with 24vac, power mic with 24vac to 12vdc converter. I've explained this in detail a few times.
-power camera off of poe+ (802.3at), run a separate cable (
cat5e or something else) to power the mic using a 12v supply or 802.3at
--running a seperate cable like this results in a larger ground loop and more audible noise
-Power the camera off poe+ and don't power the mic use it passive.
This camera and most PTZs want 24vac not 12vdc. You generally don't find PoE splitters that output 24vac. There aren't that many 802.3at splitters
