I'm in the process of replacing my home Ubiquiti infrastructure. Here's what I've decided on: Replace the US-24-250W PoE switch with an Aruba Networks S2500-24P (gigabit and PoE, 4x 10gig ports, quiet). Replace the Cloud Key Gen 2 with BlueIris for camera controller. I expect this will be able to connect to the existing Ubiquiti cameras. Possibly add one or more Ruckus R610 APs running in "Unleashed" mode to augment…
I hear these are great little boxes for running PFSence and OPNSense https://protectli.com/
I don't usually run any services since I prefer to dedicate boxes to things, but I have in the past run a number of services, including minecraft and minetest on it and it flies. Really pleased with it.
