Was on Unifi Video for a long time and like everyone else, had to make the jump to Unifi Protect when Ubiquiti decommissioned Unifi Video. I needed the HDD redundancy which the Cloud Key Gen 2 Plus didn’t have as I was running Unifi Video off a NAS. It’s well worth it as compared to upgrading the HDD on a CKG2. Very stable but it does get a little noisy with the fans going especially with 4 x HDDs loaded. It’s been running for over a week with no issues. Fully recommend it if you need the extra storage which allows for a longer period to retain your recordings.
