PoE is awesome. My custom home security system is all CCTV PoE with a gstreamer backend running on four-core fanless linux box. Way to go. Complete control. No batteries, no wares spying on me, no personal data getting scraped by big guys. (Cloud connectivity sucks because I have segmented mp4s and jogging through them hurts but I only care for events after they happen, not while they happen.)

What switch do you use? I have PoE wifi APs throughout the house, but I bought an Aruba switch and it's super noisy tbh. Fine for me because it's in the basement, but I couldn't recommend it

some netgear 8-ch poe switch. i don't recall. it's been on and running for about 8 years with no issues, way up near the ceiling of my garage, covered with dust. its plugged into a wrt1900 router i bridged via wifi to my main router.

GS308EP or EPP if you need more power budget.

Netgear are hard to beat in terms of reliability/price. They also have a 5 and 16 ports fanless version.

I also got an old Juniper EX2200 24ports and replaced the fans with quiet noctua. It run quite hot, better go with Netgear.
