Executive TL;DR
Computer vision applies neural networks to video streams to detect helmets, goggles, or proximity to a moving machine. In OHS, this can accelerate feedback and reduce human observer bias, but it introduces psychosocial risk of surveillance and discrimination if poorly designed. LGPD requires a legal basis, data minimization, and transparency; NR-12 requires that interlocks do not allow startup without protection, regardless of AI. The PGR must list intensive monitoring as a psychological risk agent.

Safe use cases in cells and logistics
A zone maintained by laser or light curtain fails less when a camera confirms human presence before reset — if the logic is dual-channel. For forklifts, collision alerts help — but they do not replace traffic design.
Engineering: accuracy, lighting, and drift
A model trained in bright light fails at night with only blue LED. Retrain per line. A PPE macro is worthless if legal dark goggles exist.
Human governance: HITL and audit
Define when an alarm only opens a ticket and when it stops the machine. Human-in-the-loop reduces serious false positives in accidents.
Privacy, CIPA, and unions
Public camera map for workers. Avoid faces in datasets — automatic blur. Short retention if there is no incident.
Integration with NR-12, NR-10, and eSocial
A filmed accident requires a chain of custody for S-2210 and labor lawsuits. NR-10: electric shock does not wait for AI.
Typical error: algorithmic paternalism
Disciplining by algorithm without union framework and documented just cause creates massive liability.
FAQ
Does AI replace CIPA?
No; it complements inspection.
Can I use facial recognition?
High sensitivity — avoid in large areas without ANPD analysis.
What about offshore cloud?
SCC clause + local law.
