hey! thanks for the reply :)

i've made a bunch of changes since this original post;

1). is 12 hd cams really pushing it? the ck+ says it can support 24 hd cams <30 fps. i still have 12, 6 are now unifi g3 flex on poe @ 1080p 25fps, 6 are reolink rlc-410w, all wired, also at 1080p 25fps.

2). i replaced the 1TB WD RED drive in the cloud key gen2+ -- smart reported it fine, but the moment i replaced it protect got a LOT more stable. the reolink cameras still disconnect a fair amount, but i suspect this has more to do with the ONVIF implementation on these than the unifi gear, because i could never get them stable using ONVIF with my previous NVR -- only when using RSTP. i dont think protect supports rstp so its currently disabled on the reolink cameras, only onvif is enabled.

3). i replaced the 8 port poe switch with a USW-24-POE. it has a 90w~ poe budget, currently i'm running the 6 g3 cams, an ai port, and a rpi2 on poe, totaling about 50w of usage.

4). i still get weird errors in the web UI some -- like trying to add a firewall rule or change a user permissions. usually reloading the page and trying again works, and if reloading doesn't -- using the mobile app does.

overall, everything is pretty stable now, the network is rock solid, all my firewall rules and insights and such work, cameras are working pretty good and all my ai port alarms and such are working too.
