Maybe the new “Snapshot Capture” feature might meet your needs to keep the camera on? It takes a single snap picture in repeating regular intervals that you set on your camera between motion events. Then when you select “Live View” you can scroll back the time bar to view the past events, which will now also play the multiple Snapshots that were taken inbetween the events. It will appear like a sped-up Time-Lapse video. So after the 30 second recording stops, you would still have interval snap pictures that might have captured the thief stealing the bike.
To set up this feature, go to “Device Settings” on the camera, select “Snapshot Capture”, turn on the Snapshot Capture and select the Frequency (with my cameras, I can select the interval for every 3 minutes, 1 minute, or every 30 seconds … and with my doorbell, I can select snap intervals of every hour, 14 minutes, or 5 minutes). I currently have mine set on the shortest available settings.
I haven’t been able to download any of the snapshots, like you can do with Event Video recordings. I think currently Snapshots can only be viewed for the 60 days with the “Protect Plus” plan.
I wish Ring could make downloading of individual Snapshots possible too. I find that sometimes I discover something interesting that occurred between the regulars video events.
