Maximum Power Draw In Cat5E

I've got an install that was first fixed by electricians in solid copper UTP CAT5e (good quality gear).  14 cameras all back to the basement DVR location via individual cables.  I have used 1 pair from each CAT5 for video with passive baluns and the other 3 pairs twisted together for power.  All cameras working great.

 

My supplier stated that the CAT5 permits a maximum of 12 volts, 360milliamps with 3 pairs used for power.  Anything over this could heat up the cable.  I have used appropriate cameras for the install without issue.

 

I wondered if in the real world there was a higher draw that cameras can use that would be OK over CAT5e... anyone know the limits from an install they have done (obviously with cable length affecting drop this would need to be taken into consideration).

 

Thanks all!

You definitely send more than that. Poe is 48v iirc

Half way down page...

Your max run (for data) should be 90M

It looks like 0.577 amps per core & 125V DC max
