Thanks for all the info and the detailed response!
But it sounds like you only need it to be a wired router, which is good.
Correct, don’t need wifi.
PoE ports as a requirement is what narrows your options considerably I think
I’m happy with doing this through a separate switch, but I’m happier if I can have less things to plug in. It’s not a must have though.
Mikrotik has a lot of routers with PoE out. Their newest model in the RB5009 series can do either passive or 802.3af/at PoE out. Many of their older routers have passive PoE only. Make sure you know what your cameras need.
I don’t have cameras yet, but I’m considering some Reolink ones. Happy to take suggestions. Am I likely to find a lot of difference in the PoE type or are most things compatible with each other?
