Stick Up Camera Elite - Motion detection not consistent

Here’s a better example of this problem.

My settings

Record Motion ON

Motion Alerts ON

Motion Sensitivity PEOPLE ONLY MODE

Motion Zone ALL DRIVEWAY

Snapshot Capture ON, EVERY 1 MINUTE

Camera location 11’ ABOVE DRIVEWAY

The first screenshot (from snapshot capture) shows my car backing out of my garage that didn’t trigger a Motion Event. The second screenshot shows my car coming returning to the garage that did trigger a Motion event.
