No helmet inside the lifting zone
A flatbed lorry is being unloaded with a lorry loader crane. A pack of concrete slabs hangs from the hook at mid height. A man in a maroon shirt, no helmet and no hi-vis vest, walks past the front of the load, a couple of steps away from it. Up on the bed, the worker who slung the pack is wearing his kit.

What it recognises in this scene
- person without PPE
- load on the hook
- lorry loader crane
- slinger
- flatbed lorry
The rule
You decide once. IRIS applies it always.
If
a person enters the marked-off lifting zone while a load is hanging on the hook
Then
- alert the crane operator and the site manager with the camera and the image of that moment
- say whether that person is wearing a helmet and a hi-vis vest or walked in without them
- log the lift with the time, so it can be reviewed afterwards
The instruction that set it up«While the lorry is being unloaded, tell me if anyone steps inside the crane's working radius — even if they're only passing through.»
What changes
What changes for whoever answers for the site
The lifting zone gets coned off and taped, and it works until somebody is in a hurry. A supplier coming over with a question, a visitor, a tradesman cutting through because it is quicker: ten seconds, and in ten seconds he is under the load. Today only whoever happens to be looking sees it, and the crane operator is looking at the pack. IRIS watches the marked-off zone for as long as the lift lasts, raises an alert the moment someone steps into it, and says whether they walked in with their kit on or without it. The alert reaches the site manager while it is happening, and he can stop the unload. He stops it, not IRIS.
What people usually ask
Can IRIS stop the crane or block the unload?
IRIS cannot stop the crane or block the unload. It does not command any machine and it does not operate anything. It raises an alert while the situation is happening, with the camera and the image, and the one who decides to stop is the crane operator or the site manager. It does not replace the banksman or the health and safety plan either: it exists so the warning reaches, in time, the person who can actually stop the lift.
Is this for disciplining whoever walks in without a helmet?
It is not for disciplining anyone. IRIS detects that a person is inside the marked-off zone and whether they have their kit on; it does not detect who that person is. It does not recognise faces, it does not compare them against any database and it does not store anyone's identity. The alert points at a lift that needs stopping, not at a particular worker.
How does IRIS know where the lifting zone is?
IRIS knows where the lifting zone is because somebody draws it on the camera image: you mark the taped-off area and that is it. You can move it the day the lorry unloads somewhere else, and you can have several zones on the same camera. It is a line drawn on a picture, not building work: the person in charge does it in a moment.
Simulation · how IRIS works
A camera looks. IRIS understands what it sees.
An extract of the real screen, no voice-over and hands-free. Each round poses another situation. What sits behind it is a good deal bigger than what you see.
- Four cameras at once
- Each understands its own view
- The numbers climb by themselves
Next step
What does a shopping centre see beyond the visitor count?
12 cases: 4 raise an alert when something happens and 8 only measure. You see each image as it is, and then with what IRIS understands on top.
What does an airport see before the queue forms?
14 cases: 7 raise an alert when something happens and 7 only measure. You see each image as it is, and then with what IRIS understands on top.
And the best part
You already record.The hard part was always watching it.
Years of video that only get opened once something has gone wrong. IRIS understands those same images as they arrive, so the answer no longer lives only in the archive.
