The enforceable work-zone case: speed. The SmartFlagger is arm-up with a flashing yellow, so traffic is moving and only the approach speed is measured. The signal and barrier state are recorded as context around the reading, not as the violation.

1. Approach speed against the posted limit
2. Signal and barrier state as context
3. Authorized review

The same work zone under stop control: the arm is down and the signal is showing stop. The scene captures a vehicle passing that state and records what the control was displaying at the moment it happened.

1. Stop state displayed
2. Pass captured against that state
3. Authorized review

CAM-01 observes the approach from well before the intersection rather than from the signal itself, measures speed across that approach, and captures the green-to-yellow-to-red sequence alongside the crossing — so the record shows the decision, not just the moment. Installation sits anywhere in a typical 70–120 ft range, depending on the intersection.

1. Speed measured across the approach
2. Signal sequence + stop-line crossing
3. Authorized review

A vehicle stops inside the marked bus-stop zone while the kerb around it is legitimately parked. The scene shows the marked zone, the vehicle occupying it, and the record that follows.

1. Vehicle inside the marked stop zone
2. Event captured with plate evidence
3. Authorized review

Connected roadside infrastructure observes a defined reserved-lane zone. A fixed lower fisheye camera detects the vehicle inside the zone; a separate camera on the post captures the license plate. Two cameras, two jobs, one record.

1. Fisheye detects the zone event
2. Second camera captures the plate
3. Authorized review
