Small observation I've noticed is that if you have your pre-trigger buffer set high (I had mine at 5 seconds) that when it sends the alert to Sentry for processing it seems to send some of the first frames in the alert which could very likely be nothing if the subject is out of frame during the pre-trigger buffer time.
When I lowered my pre-trigger buffer down to about 1 second that seemed to resolve the issue at the expense of possibly losing some video due to lag, make times....etc.
