The truck pulls away with a worker still inside
Mid-morning at dock 12. The trailer has pulled forward and come away from the door: there is already an open gap between the truck bed and the yellow leveller. Inside the trailer, a worker in a hi-vis vest is still there, pushing a pallet truck with a pallet of boxes. From the aisle, a colleague is running towards the dock with one arm raised. The door light is green. IRIS sees that the trailer has moved and that the ramp and a person are still inside.

The rule
You decide once. IRIS applies it always.
If
the trailer comes away from the dock with the leveller down or a person inside
Then
- alert the guard post and the dock supervisor straight away
- save the video from ten seconds before the trailer moved
- record how many people were inside the trailer at that moment
The instruction that set it up«Tell me the moment a trailer moves off the dock while the leveller is still down or somebody is still inside.»
What changes
What changes for whoever answers for the plant
This is the fall everyone in a warehouse has heard about, and it happens in three seconds. The chock is not always in place, the light gets switched too early, and the person inside cannot hear the engine. With the camera, the alert reaches the dock and the guard post the instant the trailer moves, not when somebody shouts. And if something does happen, the whole sequence is there for the investigation.
What people usually ask
Can IRIS stop the truck?
No. IRIS does not act: it does not brake a vehicle, close a door or send anyone anywhere. What it does is alert, right away, the people who can, with the camera, the dock and the picture of what is happening. The decision and the manoeuvre belong to a person. All the camera achieves is that the person finds out in the first second.
Are the wheel chock and the dock light not enough?
They are the first barrier and you need them. But the chock sometimes does not get placed, the light sometimes gets switched too early, and the driver sometimes does not look at it. The camera replaces neither: it watches that both are being used and raises the alarm when the trailer moves anyway. It is one more layer, not a substitute.
Does it tell the truck's movement apart from the forklift going in and out?
Yes. The rule watches the edge of the trailer against the dock frame, not general movement in the scene. A forklift going in and out does not move that edge; a trailer pulling away does. The tuning is done at commissioning, with footage from that particular dock, because every door has its own geometry and its own leveller.

Shopping centres
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.
Airports
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
The rule does not decide anything.It just never forgets, and it tells the person who decides.
You write once what needs watching, and it holds at three in the morning just as at noon. What to do with the alert is still a person’s decision.
