Good afternoon!
I'm looking at moving a wall-mounted digital intercom unit to a place further down a hallway. It's connected with a Cat5e cable, and powered through PoE running over the same cable. It's not possible to move or replace the cable, so it will have to be extended.
The two available options seem to be a female-to-female RJ45 extender, or a female-to-male Cat5e cable. Both support PoE. My main concern is that the cable is powered by a source outside of our control. The intercom unit draws negligible power whilst idle at most, but theoretically PoE is able to support much higher power capacities (100W according to IEEE 802.3bt). However unlikely, malfunctions in the intercom system could create for such peaks, I guess.
Since the extension will happen within the interior walls (that will be plastered over), my question is whether there are heat or insulation considerations to take into account for either of the available options?
Many thanks,
Peter
