Couple things looking at the device info, your Skybell is currently set to medium quality settings. That might account for the apparent change if your Skybell was added to a new Surety account and the default setting was different from what you were previously using.
Check in Video Settings when logged into Alarm.com and select Video Device Info for that Skybell. It is currently set to 720 (Good Quality), try upping it to the 720 (Better Quality) option. Any change?
It also looks like there is a newer supported firmware version for your Skybell. It would be good to update to the latest version.
