If you're considering Reolink, why not self-host their software? 24/7 recordings and motion detection can be stored locally on your NAS, as well as on the camera's SD card if you wish. Their app for phones, tablets is wife-friendly, and they can integrate with HA.
I wouldn't bother with their hub. Two 12mb cameras sending footage over a 100mb connection which writes to SD cards isn't ideal. I experienced lock-ups and drops. There is a Hub Pro, which has HDD's, but this wasn't easily available in the UK at the time I tested.
I moved away from Unifi cameras as I found Reolink a better value. I have 2 x dual cameras, 2 x 4k PTZ and a few 4k dome cameras, which are over 3 years old now. Simple, effective, and they don't cost the earth for what they are. There are always offers on Amazon and the Reolink website, so you can land lucky.
Be careful not to overcomplicate something which needs to be reliable, easy to use and needs little maintenance/intervention.
