Night gathering in the square
It’s the middle of the night and the square is full: one large group in the center and smaller ones spread around it. There are bottles across the ground, the trash cans are overflowing and the patio at the back is still open.

The rule
You decide once. IRIS applies it always.
If
crowd density in the square exceeds the configured threshold
Duringmore than 20 minutes
And alsobetween midnight and 6:00 a.m.
Then
- notify the local patrol
- schedule extra cleaning
- log the hourly occupancy
The instruction that set it up«Tell me if people gather in the square above the threshold at night, and how full the trash cans are.»
What changes
What changes for whoever runs the city
One thirty in the morning, the venue two doors down has just let out, and the phone at the desk doesn’t stop: the neighbors on the second floor call every night and always say the same thing. Whoever heads out that night doesn’t know whether there are a hundred people on the sidewalk or three hundred, and the next morning nobody can say how many there were or when they left. With IRIS that call comes with a number: the alert fires when the threshold the city set is crossed, with occupancy measured hour by hour and the trash by the dumpster counted in the morning. The following month the extra cleaning shift goes on the right night, explained with numbers instead of with the impression of whoever happened to walk past.
What people usually ask
Does measuring how many people are in a square mean identifying them?
No, measuring how many people are in a square does not identify anyone: IRIS works with density and counts, not identity, and the figure it produces is how many people are in an area, not who they are. What gets stored, for how long and who may see it is set by the city, and the system can be deployed locally, with no images leaving the site. The measurement is there to size cleaning and patrols, not to follow anyone.
Does IRIS listen to what’s said in the square?
No, IRIS doesn’t listen to what’s said in the square: it works with the image, not with audio. In this scene what it measures is how many people are in the area and the state of the trash cans; it does not record conversations and it does not identify anyone. If the city wants to measure noise, that’s a separate sound-level meter and its own decision, not something IRIS does on the quiet.
Can IRIS tell me when to send the cleaning crew?
Yes, IRIS helps decide when the cleaning crew goes in, and that’s usually the use that pays off most. Because it is recorded when the square fills and when it empties, week after week, the real pattern of that spot becomes visible and the next day’s cleaning shift can be adjusted. It’s the same data that raises the night-time alert, looked at calmly and over months.
Simulation · how IRIS works
No extra alarms here. Just what needs looking at.
Not a recorded video, not an explanatory drawing: a summary of the real screen, with a different case every time it starts. There’s a lot more behind it.
- You draw the line
- It counts by itself
- A number comes out
Next step
The highway
Who watches an entire highway?
10 cases: 8 raise an alert when something happens and 2 only measure. You see each image as it is, and then with what IRIS understands on top.
Public transport
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.
And the best part
We’d rather promise less.Let the first week be the surprise, not the brochure.
What it can’t do gets said on day one, not on the last day. A short list that holds beats a long one that falls apart the moment it is turned on.
Tell us your problem and we’ll say whether IRIS understands it, or not yet.
A person answers, the same working day.
