Welcome to the Wyze User Community Forum @jmsmith!
The Wyze AI Tagging Engine happens on the Wyze Server. The cam is only responsible for detecting motion anywhere within the Detection Zone, marking it with the green Motion Tracking box, and pushing an upload to the server. Once the Motion Activated Uploads happens, the cam is done and onto the next motion trigger. It has a very short attention span.
Once the Video gets to the server, the AI Engine takes over. It looks at every frame, either 20fps day or 15fps night, to see if there is a Person, Pet, Vehicle, or Package depending on your settings. It does not see motion, only still images. A 10s daytime upload is 200 frames or 200 still images.
The AI Engine looks at every object within the FOV for a match. Since your Car is parked there and you have Vehicle selected, it will return a Vehicle tag every time an upload occurs because of some other Motion Activated Upload.
Crank up your sensitivity and you could experience hundreds of these in a short time.
