The water climbing the steps
Night, after hours of rain. The water is coming down brown and foaming through the lined channel and has covered almost the whole flight of access steps: three treads are still above it. On the wet walkway a small group stands watching, and more people lean over from the bridge. IRIS reads how high the water stands against the stone treads, which have been there for as long as anyone remembers and don’t move.

What this camera measures
An alert says something’s happening. The reading says how much.

The series, not one figure
One number says nothing. A curve does.
The water on the steps, every ten minutes
- Height above the first tread
- Level at which access closes

The rule
You decide once. IRIS applies it always.
If
the water covers the tread the city has marked, or rises faster than the rate that has been set
Then
- alert the civil protection officer with the camera, the reading and the last hour’s curve
- say how many people are leaning over the channel at that moment
- repeat the alert every ten minutes while the water keeps rising
The instruction that set it up«Tell me which tread of the steps the water has reached, and alert me when it passes the one we have marked.»
What changes
What changes for whoever answers for the site
“The water is seven feet above the first step” tells nobody anything. It may have been like that all afternoon. What decides whether the access gets closed isn’t the height: it’s the rate. The first ten minutes it rose six inches; the last ten, twenty-five. That slope is visible at a glance on the chart and doesn’t fit in a single number. The person on duty looks at the curve, sees where the level the city set sits, and decides to close the steps before anyone has to be pulled off them. IRIS closes nothing and predicts nothing: it reads a height against a stone that’s standing there, and draws it as it changes.
What people usually ask
Does this replace the catchment sensors?
No, and it’s worth being blunt about it. This is a reading against a visible reference — a flight of stone steps — taken with a camera, and it’s only good for the stretch of channel that camera sees. It isn’t a hydrological warning system: it doesn’t measure discharge, it doesn’t know what’s happening miles upstream and it doesn’t announce a flood wave. The catchment sensors and the emergency service go on doing their job exactly as before, and this camera takes no function away from them. What it adds is the thing they lack: what’s happening at this precise spot, and whether anyone is standing in front of it.
Does IRIS warn that a flood is coming?
No. IRIS doesn’t predict. The chart only has data to the left of now: there’s no curve drawn into the future, because IRIS doesn’t know whether in ten minutes the water will go up, go down or stay where it is. What it shows is what the water has done up to this moment against a reference that doesn’t move. With that, a person decides. Without it, they decide anyway — blind.
And at night, or with the water running very dirty?
The reading isn’t about the color of the water: it’s about where the waterline sits against the treads, and that shows up just as well at night under the walkway lights. When the camera can’t read the reference — thick fog, rain on the lens, a dirty housing — IRIS says so and stops giving the reading, rather than giving an invented number. A reading that fails silently is worse than no reading at all. And as for the people leaning over, IRIS counts bodies and nothing else: it does not identify anyone, it does not recognize faces and it does not read license plates.
Demo · IRIS at work
Watch what happens. Then watch what IRIS does with it.
Not a recorded video and not a drawing: it’s a summary of the real tool, with a different case each time round. The whole tool doesn’t fit in a box.

Next step
Who watches a whole station at rush hour?
17 cases: 11 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 sees the sales that never reach the register?
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.
And the best part
What you bought was a warehouse of images.What you needed was someone to look at them.
Those same cameras that only fill disks today can flag what matters while it’s happening. The warehouse stays; it just stops being all you have.
Tell us your problem and we’ll say whether IRIS understands it, or not yet.
