Water building up in the tunnel
A vaulted drainage tunnel, with a blue band painted along the walls. Water has built up on the invert and two workers in helmets and hi-vis are wading through it, ankle-deep. On the right, a jet comes in through the wall and falls onto the ledge. On the left, the run of pipes and a red valve. IRIS reads how far the water still is from the painted band and how many people are inside; it does not know who any of them are.

The rule
You decide once. IRIS applies it always.
If
water builds up on the tunnel invert and rises towards the painted band on the wall
Then
- alert the network manager and whoever is on duty, with the camera and the height relative to the band
- say how many people can be seen inside the tunnel at that moment
- repeat the alert for as long as the water keeps rising
The instruction that set it up«Tell me if water builds up on the tunnel invert while there are people inside, and tell me how far it still is from the painted band.»
What changes
What changes for whoever answers for the site
A drainage tunnel is a place where the water can change height far faster than a person walks, and whoever is inside is the last to know, because they cannot see what is coming. Up above there is a picture nobody is watching. This promises nobody will be trapped: it makes the person up top see the height and the number of people while it is happening, so they can call before the only source of information is a call from below.
What people usually ask
How do you measure the height without a sensor?
With a reference that is already on the wall. The painted blue band, a joint, a step: anything fixed and visible that somebody marks once on the image will do. From then on the reading is how far the water still is from the band, which is what a worker would work out by looking. It is a reading against a visible reference, not a level sensor, and it neither replaces one nor claims to.
What if the tunnel is dark?
In a tunnel the lighting is part of the installation, and where it does not reach you add support lighting or a low-light camera, exactly as you would to see it with your eyes. What you do not do is promise a reading the image cannot give: if the scene cannot be seen, IRIS reports that it has lost the reference instead of inventing a height. An honest notice that it cannot see is worth more than a made-up number.
Does it keep tabs on the workers inside?
No. IRIS does not identify anyone: it does not recognise faces, it does not read number plates, it does not compare against any database and it does not store who anybody is. It counts how many human figures are in frame, because that number changes what you do with the alert, and that is where it ends. Who each of them is, how long they take or how they work is not measured here and cannot be measured with this.
See it for yourself
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
Who is watching a whole quay at three in the morning?
14 cases: 13 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.
Who is watching the cameras of a whole branch network?
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
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.
Tell us your problem and we will say whether IRIS understands it, or not yet.
