I have a dozen or so PoE endpoints, working well for a decade-ish. Three wireless APs, one router, and the remainder cameras. Mikrotik has enterprise capabilities, and most importantly to me security updates for years, but also a quick start mode. Incredible value and forum for support. Watch out for PoE endpoints that don't handshake to the proper Voltage, lest the magic smoke escape. (Electronics run on magic smoke, so never let it leave the circuit board.)
