Safety, PPE and site monitoring
In short
Camera-based safety on a working site — PPE and restricted-zone detection, forklift and pedestrian conflicts, intrusion after hours — and the incident workflow that has to exist before any of it changes behaviour.

- A PPE violation is a record with an owner, not a red box on a screenA red box on a monitor is not a violation. The record underneath it — zone, rule version, duration, clip, owner, state — is what a supervisor actions and an auditor reads.definition7 min
- Drawing a restricted zone on a camera view: what the polygon meansThe polygon is the smallest part of a zone. The entry rule, the dwell condition and the assumption about where the floor is are what decide who gets alarmed on.definition7 min
- What a camera may call a near miss, and what still needs a human reportCameras measure distance, speed, dwell and crossings. A near miss is a claim about what nearly happened — so camera events belong in the process as candidates, not as counts.definition7 min

- Everything works until the cameras switch to infrared at duskThe collapse tracks the camera's day-night switch, not sunset. Once the infrared cut filter drops out, a colour-keyed vest class is scoring on a monochrome frame it has never seen.diagnostic10 min
- The incident nobody has footage of: auditing coverage after the factMissing footage is a finding, not a dead end. Five causes look identical in the moment and carry completely different remedies, and only one of them needs a new camera.diagnostic10 min
- Three hundred alerts a shift and nobody opens themA shift raising 300 alerts and closing 6 has an aggregation fault, not a discipline problem. Five causes, ranked, and the event model that turns hundreds of detections into one incident.diagnostic11 min
- Wearing a hard hat and still flagged: tracing a false PPE violationOpen the evidence clip and ask whether the head is visible at all. That one question splits false PPE flags into three groups that need three unrelated fixes.diagnostic11 min
