Real-time multi-sensor pipeline on the conveyors, dispatch belts, and loading gates where every unit crossing the line is a unit of revenue. RTSP feeds ingested at 4, 8, 12 streams per site in parallel. Detection, tracking, and line-crossing logic split deliberately so the system tolerates occlusion, motion blur, and dropped frames without double-counting or losing units between frames.

The camera count is cross-validated by two independent sensor channels at the same line: a motion sensor that confirms physical pass-through, and a heat sensor that confirms the unit's thermal signature against the expected envelope. Any disagreement between vision, motion, and heat is flagged as a contested count rather than silently reconciled. The system never picks a winner without surfacing the conflict.

Every counted unit written to a tamper-evident binary audit log so the operator's count, the dispatcher's count, and the counterparty's count reconcile against a record that was not editable in the moment it was produced.
