CAM-409
An open hatch and everybody walking straight past
Early afternoon at a pumping station. In the middle of the yard, the steel lid of an access hatch is tipped up on its hinge and the opening is left uncovered, with the yellow ladder going down inside. There is no barrier, no chain, no cone: only the stripe painted on the ground. A worker in a helmet and hi-vis vest walks two metres past without stopping. Behind him, the pump room door is standing wide open too.

The rule
You decide once. IRIS applies it always.
If
a hatch or an access door has been open for longer than the agreed time and there is nobody next to it
Then
- alert the supervisor with the camera, the time and the video of the moment it was opened
- keep the sequence from the moment the lid was lifted
- log the alert in the daily report with the opening and how long it has been open
The instruction that set it up«Tell me if a hatch or a door is left open for more than twenty minutes with nobody beside it.»
What changes
What changes for whoever answers for the plant
An open hatch makes no noise and sends no signal: there is nothing in the control room that says this hole has been waiting for half an hour. Somebody opens it to go down, comes back up, goes for lunch and leaves it like that. This camera puts a clock on every opening and raises the alert when it passes the agreed time with nobody beside it. The site manager decides whether to have it shut or whether there is work going on below.
What people usually ask
What if somebody is working down there?
Then it should not raise anything for being open, and it does not: the rule measures how long the opening stays uncovered with nobody beside it. While there is a person next to the access, the clock does not run. When the hatch is left alone, it starts counting, and after the number of minutes the site has agreed, the alert goes out. Going down into a confined space is a different rule, with its own attendant.
Can it tell an open hatch from a closed one?
Yes, and it is among the easiest things a camera does. A closed hatch is a continuous surface; an open one leaves a dark rectangle, the leaf tipped up and, here, a ladder in plain sight. That reads from a distance and in poor light. What the camera does not know is whether that hatch was meant to be open: the work permit says that, which is why the alert carries the video.
Can the same rule be applied to doors?
Yes. It is the same idea: an access left open for longer than agreed with nobody nearby. It works for the hatch over the wet well, for the pump room door and for the compound gate. Each access gets its own time, because a door people go through all day is not the same as a lid over a shaft. Those times are set by the site.

Simulation · how IRIS works
Everything comes in. Only what matters gets through.
This sums up what IRIS does with one alert, from the moment it appears until it is closed. The real screen holds far more; this is the main thread.

Next step
How long before somebody comes down that corridor at four in the morning?
13 cases: 12 raise an alert when something happens and 1 only measure. You see each image as it is, and then with what IRIS understands on top.

And the best part
You decide the rule onceand it is applied the same way every time.
At three in the morning it means what it means at noon, on camera one and on camera four thousand. It does not depend on who is on shift, or how tired they are.
