Counts: Mixer truck arrivals · Counts events

Can: Count mixer trucks crossing the gate line, inbound.

Mixer truck arrivals by day. Not known, because the camera was down 11 to 21 May (11 days, hatched).

Recording on 80 of 91 days, down 11 to 21 May. The count covers 88% of the quarter.

Accuracy: Precision 96.2% (93.9 to 97.6), recall 94.1% (91.4 to 96.0), from 418 movements labelled by your own team, 14 May. The labeller is the camera’s own party.

A reviewer or the lead, never the person who labelled it, accepts or withdraws this measurement under their own name. Accepting is not available in the demonstration.

CAM-YARD-01 Your camera · The block-stack bay

What a camera or sensor can never give

  • Composition by mass: refused at setup. Use the receiving facility’s records.
  • Water chemistry: refused at setup. Use a laboratory sample.
  • Air pollutant concentration: refused at setup. Use a stack or room analyser.
  • Refrigerant leakage: refused at setup. Use the handler’s logbook and a weighed cylinder ticket.
