Zone presence tracking

Every person in a fixed-camera stream is detected and tracked, and time spent inside named regions is logged. No region is seeded by hand and nothing is clicked to start a track.

Zones drawn and renamed in the browser; each keeps its own visit log with a live dwell clock.

Fourteen people in shot. Per-frame cost does not grow with the number of people tracked.

How it runs

Detector: D-FINE (Apache 2.0), every person per frame
Tracking: Greedy IoU association
In-zone rule: 25% or more of a person's box overlapping the region
Throughput: ~230 ms/frame at 3 Hz, CPU only, measured on a 20-core desktop
Hardware: No GPU required

These are recordings of the application running on stock footage. Detection accuracy has not been formally validated. The throughput figures above are measurements; no accuracy figures are claimed.
