CAM-392
Clearing stone by hand with the belt still live
First thing in the morning at the crushing plant. A worker in a yellow helmet and hi-vis vest has leaned right onto the conveyor and is pulling stone off by hand. The mesh guard that covers the drum has been taken off and propped against the walkway. The orange start beacon is lit. The belt can start on its own at any moment. IRIS sees a person on the belt and a guard out of place.

The rule
You decide once. IRIS applies it always.
If
a person touches the belt or the drum guard is missing
Then
- alert the control room with the belt, the camera and the time
- save the video from the moment the person climbs onto the belt
- time how long the person stays on the belt
The instruction that set it up«Tell me the moment anyone climbs onto a belt or a guard is missing, even if the belt is stopped.»
What changes
What changes for whoever answers for the plant
This is the classic accident at an aggregates plant, and hardly anyone ever sees it: it takes two minutes, with no witnesses, while the belt has been idle for a while. With the alert as it happens, the control room finds out while the worker is still on the belt and there is time to call him off. Afterwards the video remains, and footage of your own plant teaches more in two minutes than a whole safety talk.
What people usually ask
Does IRIS know whether the belt is locked out?
No. Lock-out is reported by the electrical system, not by the image. What the camera sees is a person on the belt and a guard out of place, and that alone is enough to raise the alert. If the plant shares the lock-out status, the alert can tell the two cases apart; without that input, IRIS warns whenever somebody climbs on.
Is a written lock-out procedure not enough?
The procedure is necessary, but it is only followed if somebody is watching. The camera watches all the time and warns while it is happening, not at next month’s review. And it leaves the footage of the moment, which lets you discuss the actual case instead of repeating the rule in a meeting room.
Does IRIS recognise which worker it is?
No. IRIS identifies nobody, recognises no faces and compares them with no database. It sees that there is a person on a belt with the guard removed. Who that person is comes from the shift roster and the report, and what happens next is decided by the company, not by the camera.

See it for yourself
A new case each time. Always the same screen.
It plays by itself and shows one case from start to finish. It is a summary: the real screen has far more functions than fit in this box.
- The rule gets built
- It goes to every camera
- Published, it watches alone
- And then it fires
Next step
Who sees the sales that never reach the till?
10 cases: 4 raise an alert when something happens and 6 only measure. You see each image as it is, and then with what IRIS understands on top.
Who is watching when the load swings over somebody?
11 cases: 9 raise an alert when something happens and 2 only measure. You see each image as it is, and then with what IRIS understands on top.
And the best part
The door was left open at two.Finding out at nine is no use to anyone.
The video tells you at nine. IRIS says it at two, with the camera, the time and the images from that moment. The difference between the two is whether someone can go.
