Mark a place. Keep watching it.
Watch Areas
The feed and event layer stay side by side.
The red polygon is registered across the pass. Vehicle tracks produce one entry when a vehicle moves into it. Use the timeline or open any event to check the exact moment.

The useful distinction
An area belongs to the scene, not the screen.
A fixed screen rectangle silently changes meaning when the drone moves. The polygon follows the same patch of road through the clip, so the entry rule keeps asking one stable question.
When registration is not reliable enough, the production design is to stop emitting events and report the gap.
Register each frame
Registered geometry keeps the polygon attached while the aerial camera drifts.
Write the event
An outside-to-inside transition becomes a timestamped entry tied to its track.
