Video recording buffer

I had a Ring stick up wired cam previously which had issues with black screen during playback which was replaced (gratefully) by Ring. The new cam seems to record differently. Previously, I’d view playback of, eg: a walker passing by and the playback would begin just before they appear in view, record for the whole time they were in view - even if they stopped - and continue recording until they passed just out of view. However, now - whether it be a person, cyclist, car, whatever - the video playback starts when the subject is already in view, sometimes stops recording while the subject is still in view (for example if it/they are stationary), and finishes playback before the subject has gone completely out of view. I feel as though I’m missing a great deal of potentially valuable video. Has anyone else noticed this and possibly know what’s going on? Thanks in advance
