I upgraded my venerable USG with the new UXG as I have gig service now. The gear is great, even supports IPv6, and uses much less power. But… no internal DNS is enabled. So now, I ended up buying a thin client on eBay to roll my own DHCP/DNS. Not fun. It is baffling to me because there’s lots of complex new features in the Unifi stack, and they already had an interface to configure static names in dnsmasq.
I went the Eufy route for cameras as the batteries were a big draw for me.
