Red laser threshold projected directly from the SmartFlagger. Crossing it initiates the vehicle evidence sequence.
SaferSmart Zones Evidence CameraA separate evidence camera captures the vehicle and license plate as the candidate work-zone event moves through the controlled area.
Approaching VehicleCone Pro detects the vehicle and its approach speed. SmartFlagger provides the traffic-control and recorded-video context; SSZ adds the vehicle and license-plate evidence to the event package.
LTE ConnectivityMaintains remote connectivity for device health, telemetry, alerts and operational visibility.
Scenario B · Stop-Control Pass
Show the stop state.
Capture the pass.
Build the safety record.
This scenario demonstrates the current enforceable construction-zone use case: speed. The SmartFlagger is arm-up with yellow flashing; that traffic-control state is captured as context while SSZ documents a materially excessive speed event.
