I have a C8 and am considering running a POE line to it instead of both power and ethernet wires. Will this POE splitter work for me ? It has a Gigabit Ethernet & 5V USB C plug.

It might. Might not. The issue is the RF noise generated in the power reduction circuit. 48v in to 5v out.
This one is working for me on my C-8s:

Oh thank you for the quick response! I think that'd be better. Haven't thought about the noise aspect. Your splitter also seems to have screw anchor points. Very handy indeed

The definitive study, w/splitters tested and confirmed yay or nay.
In the hope that it will be useful to others, I thought I'd share my testing of the C8 powered via PoE.
There have been many references to issues when powering C7/C8 units using Unifi switches, but it should be understood that these issues are not specific to Unifi. My main switches are Cisco CBS 350s (192W), and while I had no issues powering C7s with inexpensive lightweight PoE splitters, the C8 has been a completely different story. FWIW, I've also tested with a dedicated Trendnet PoE switch…
