If you’re buying new cameras they’ll be 802.3af PoE. Passive is becoming much less common. So that model router I linked would work great.
I think if you’re a moderately technically inclined person you would be happy with that solution. If you are intimidated at the idea of writing or adapting some scripts, I would probably recommend a router on one of the other platforms plus a PoE switch.
LULd for sure.
