Eufy Video Doorbell - Reject events where a face cannot be found

When a person is at the door, Eufy does a fantastic job at picking a face and presenting it as the thumbnail. When motion of a bush triggers an event, I get a thumbnail of the bush. Clearly the algorithm doesn’t see a face but it fails to reject the event. Tie this to the Sensitivity setting.

Yes, this should be how it already works but it does not. Anker, please make this easy fix.
