The rule
You decide once. IRIS applies it always.
If
a person paints on a wall or a facade
Duringmore than 30 seconds
Then
- alert the city’s duty desk
- keep the video from the start
- open a cleaning job for that wall
The instruction that set it up«Tell me if someone is painting a wall, and keep the video from the very start.»
What changes
What changes for whoever runs the city
The maintenance engineer knows that wall: he repaints it three times a year and he always sees it the next morning, already dry. The tagging happens at night, in an underpass nobody walks through, and nothing survives of it: no image, no time, nobody to bill. With IRIS the alert goes out while it’s happening, with the camera open, and the city’s duty desk decide whether to go. If nobody goes that night, what’s left is the video from the first stroke and a record for that wall: with it the engineer can ask to protect the surface instead of repainting it again.
What people usually ask
Can IRIS tell a commissioned mural from illegal graffiti?
No. IRIS doesn’t tell a commissioned mural from paint nobody asked for: it recognizes that somebody is painting a wall, not whether they have permission. What the city does is mark the authorized walls and the dates of each commission on the map, and IRIS stays quiet there. It’s the usual idea: the organization sets the rule once, IRIS applies it every day.
Does IRIS alert while they’re painting or once the graffiti is done?
IRIS alerts while they’re painting, not once the graffiti is done. That’s the difference from checking the wall the next morning: the alert goes out there and then, with the camera open, and there’s still time to act. If nobody picks it up that night, the video, the time and the exact spot are still on record, which is already a good deal more than there usually is today.
Does IRIS detect graffiti at night, with little light?
IRIS detects graffiti at night as long as the camera at that spot gives a usable picture with the street lighting or infrared, and it is calibrated on that night-time image, not on the midday one. Where the light doesn’t reach, detection becomes less reliable, and that’s stated in the point-by-point survey rather than promising that everything is visible.
Demo · IRIS at work
We won’t just tell you. We’ll show you.
It’s a summary of the real screen: it plays by itself, step by step, and shows only the path of one case. The actual tool has far more than fits in here.
- It lands in the tray
- You open it
- You confirm or dismiss
Next step
And who watches the cameras?
34 cases, and in every one of them IRIS raises an alert when something happens. You see each image as it is, and then with what it understands on top.
Who watches the cameras of a whole city?
23 cases: 18 raise an alert when something happens and 5 only measure. You see each image as it is, and then with what IRIS understands on top.
And the best part
Nobody covers the night shift:the camera that is already on covers it.
It doesn’t tire, it doesn’t blink and it doesn’t go for coffee. What happens at night is understood just as it would be at midday, and whoever is on duty hears about it while it’s happening.
Tell us your problem and we’ll say whether IRIS understands it, or not yet.
A person answers, the same working day.
