Ehh, I have a mix of 4K and 2K cameras, it hasn’t been much of an issue. I run OPNsense with a single EAP670 and there hasn’t been much performance degradation. PoE is definitely ideal but not an option for many, including me since I rent. I think the G.hn plugs are probably my best option for PoE if I really needed it.
Edit: not sure why you’re being downvoted
