Notes from the control room.
Product updates, safety research, and engineering deep-dives from the team.
How we got PPE detection to 98.2% precision on the factory floor
Benchmarks are easy. Mondays at 6am with steam, forklift exhaust, and a backlit bay door are not. Our data curation loop, explained.
The hidden cost of forklift-pedestrian near-misses
Most sites report the collisions. Almost none log the near-misses. We pulled 6 months of intrusion data across 12 plants to show what you're missing.
Meridian Steel: 38% fewer recordable incidents in 6 months
Three plants, 72 cameras, one EHS director who stopped sending Monday-morning PPE memos. The full rollout, with the numbers behind it.
Rule engine v4: compound rules, PLC handshakes, and a lot less YAML
v4 ships visual rule composition, native Modbus and OPC UA hooks, and versioned rule history. Here's what changed and why.
Face redaction benchmarks: how we hit 99.7% recall at 30fps
GDPR and worker-council approval start with redaction you can actually trust. Our detection + tracking pipeline, and what it costs in latency.
What ISO 45001 auditors actually look for in video-based controls
We asked three auditors what they ask EHS managers about automated monitoring. Spoiler: it's about the audit trail, not the model.
Running 100 camera streams on a single L40S
A walkthrough of our inference scheduler, the batch sizing tradeoffs, and why we decode with NVDEC even when PyTorch would be easier.
Why we stopped trying to be a cloud company
For about three weeks in 2024 we had a cloud roadmap. Then our pilot customers asked the same question twice, and we deleted the slide.
Designing zone-intrusion rules that don't cry wolf
Dwell time, direction, class filters, and shift calendars. The four levers that take intrusion alerts from noisy to trusted.
