CAM-388

A worker on foot between a truck and a loader

Late afternoon in the quarry yard. A truck loaded with stone is moving along on the left. From the right, a wheel loader comes in with a full bucket, throwing up dust. Between the two, a worker in a hi-vis vest and yellow helmet is crossing on foot with one arm raised. On the fence behind there is a machinery-in-motion sign and a speed limit sign. IRIS sees a person on foot inside the area where two machines are moving.

What this camera measures

An alert says something is happening. The reading says how much.

11 sTime the person has been in the area
1People on foot in the yard
5Machines moving in shot
7Crossings on foot counted today
18:10Time of the crossing

The figures on this screen are an example from the illustration, not any client's measurement.

The rule

You decide once. IRIS applies it always.

a person on foot enters the area where heavy machinery is moving

Then

alert the yard supervisor with the camera, the time and the exact spot
save the video from the moment the person enters until they leave
add the crossing to the day’s count of movements on foot

The instruction that set it up«Tell me the moment anyone is on foot in the machine area of the yard, even briefly.»

What changes

What changes for whoever answers for the plant

Motor vehicle transport is the leading cause of death in mining, and it is almost always the same thing: a person on foot in a machine’s blind spot. From a high cab, the operator cannot see the ground right beside the wheel. The camera can. The alert reaches the supervisor and the control room while the person is still there, and the video is kept to review how it came to that: where they came in, why they were on foot and what was missing.

What people usually ask

Isn’t the machine’s own collision system enough?

It helps, but it warns inside the cab and only around that one machine. The camera sees the whole yard from above: who comes in on foot, where from, and which machines are moving at the same time. The alert also reaches the supervisor and the control room, and a video with the time is kept. They are two different things and they work well together.

Can it tell a person from a drum or a cone?

Yes. IRIS recognises the shape of a person and the way they move, and does not confuse them with a stationary object. What it does not do is know who they are: it does not recognise faces or match them against any list. It sees «somebody is on foot in the machine area», and that is enough to raise the alert in time.

Can walking be allowed at certain times?

Yes, and it is the normal case. The quarry writes the rules: a maintenance window, a marked walkway, a machine stand-down. Inside that, IRIS stays quiet; outside it, it alerts. IRIS does not decide what counts as a breach, it applies it. And every rule change is logged with the date it was made.
