It would be good to either capture each sequential update to the camera window, or have the phone record video itself which could then be picked up from the videos window in full quality.
If you caught someone messing with/stealing your phone you may miss an opportunity to get a clear shot of them by reacting to late or not being able to take another shot quite yet because you just took one a moment too soon. By allowing automatic sequential storage of the image used in the window (via a start/stop button) or video stored to the device then downloaded, there would be a much greater chance of getting a good shot.
