UniFi! Dream Machine to start, NanoHD to expand, and everything is magically configured across the whole ecosystem. (Or some PoE switches, a USG-4, and a cloud key if your build is bigger than a dream machine). Add a network/vlan/dmz? Just click save, and magic happens. They even have cheap *managed* 5-port PoE-powered switches for ~$25. Ideal for “behind the TV”. My setup: 48-port PoE switch; eight APs delivering 400Mbps to every corner of the house, including the back yard and garage, with minimum RSSI to force roaming; USG-4; retired 1st gen cloud key (moved controller to a container on the PC doing OpenHAB/BlueIris VM); three 8-port and two 5-port PoE-powered switches; a dozen HikVision cameras . and a partridge in a raspberry pi (also PoE).
