How this helps operations
1
Continuous automated patrol
214 cameras no longer depend on manual rotation. 12 hazard classes judged in 0.5s.
2
Every call is auditable
Each detection keeps its confidence score and rationale, so false positives can be reviewed.
3
Triage by class
Spills, overflow, doors, queues and objects route to the teams that own them.
