I had started down the path of going all Ubiquity ~5 years ago. I started with cameras and their camera controller. It was super flaky, when everything was working, it was great, first class app experience. But any time the cameras rebooted (power outage, firmware upgrade), I would literally spend days with some cameras offline, until multiple reboots of impacted or all cameras would eventually fix it. Then, a few years in a firmware upgrade to the switch (their 250W PoE switch) caused it to start isolating my Google WiFi APs because it would do some loop detection. An hour on the phone with their support (which in that instance was really good) resulted in a a prognosis of "This particular loop detection can't be turned off." So I had to drop a dumb switch in front of the Ubiquiti for the Google APs. I was considering replacing them with Ubiquiti, but needed to run some more wire throughout the house to get what I needed. Then I ran into a firmware upgrade that bricked 3 of my 4 cameras. After going back and forth with their support and getting nowhere, I just gave up. I had replaced the controller with the CloudKey G2 at one point because the old one was no longer supported, and it seemed to help with but not totally resolve the days of rebooting cameras situation. Honestly, having the cameras bricked was a relief, because of all the consternation that the firmware updates had been causing. I just couldn't bring myself to buy new Ubiquiti cameras. I ended up pulling out all the Ubiquiti hardware, replacing it with $200 4K very low light cameras that are just amazing (rebranded HIK Vision, "Montavue"). I'm using BlueIris for the camera controller, which is fine. Still using the Google WiFi, which continues to work great. I have 4 APs (one in router role, 3 spread around the house).
