I used shielded and properly grounded cat6, and even then I was seeing spurs and noise all over from 2m down. Granted the cat6 run was basically parallel to my attic antenna just about 5 ft from it for nearly the entire length.
I put one ferrite ring on both ends of the run with 5 turns through each and nearly entirely killed spurs I had been seeing all over the spectrum.
I think it may be. Its specifically just a run for IP camera so it may be negotiating at 100Mbps
