The sign is right because the number comes from the spaces themselves
Rush hour at the entrance to a level. A lit sign hangs over the roadway and splits the traffic by floor: one full, two with room and a row for charging. Three cars pass underneath; one turns toward the green spaces on the right, where a post is still free. On the ceiling, a line of green and red lights marks space by space. IRIS counts the spaces by looking at them and sends the number to the sign.

How the counting works
Counting isn’t something you ask for. You draw a line.
Over the rows of spaces there are drawn zones, one per type. Inside each zone IRIS looks at whether a vehicle is on each space and for how long. And there’s a line across the access lane: whatever crosses it is added to the entries for that level. Neither the zone nor the line can be asked for out loud; they’re drawn once over the frame and stay there, and that’s why one Tuesday’s number can be compared with another Tuesday’s.
- entry line onto the level · Counting line
- charging zone in the foreground · Dwell zone
- charging zone further back · Dwell zone
And also, one rule
You decide once. IRIS applies it always.
If
the number on the sign and the space count stop matching
Then
- correct the sign with the count made by looking at the spaces
- alert the control room with the level and the time
- save the reading and the image so they can be checked later

What changes
What changes for whoever runs the parking lot
Saturday at twelve, a driver goes up to the second level because the sign said there were twenty spaces, and up there isn’t one. By the third lap he has stopped believing the sign, and a sign that gets it wrong is worse than no sign at all. The error almost always comes from counting entries and exits: every motorcycle that slips through behind a car and every barrier left up throws the count off, and nobody squares it again until night. If the number comes from looking at the spaces, the sign corrects itself at every reading.
What people usually ask
Why does the number on a guidance sign go wrong?
Almost always because of how it is worked out. If the number comes from entries minus exits, every car that slips through uncounted and every barrier left up stays inside the tally, and the error grows through the day. Looking at the spaces, every reading starts from zero again: if twelve spaces have no car on them, it’s twelve, even if the barrier has been out of step all morning.
Can IRIS send the number to my sign and my app?
Yes. The count comes out as a figure per level, per zone and per space type, and from there it goes to the entrance sign, the traffic light, the app or whatever system the parking lot already runs. IRIS doesn’t replace that system: it hands it a number measured by looking at the spaces, and the time it was measured.
Do you need one camera per space?
No. One camera covers a whole row or a whole face of spaces, depending on the height and the angle it looks from. What’s needed is that every space is visible: a space hidden behind a column can’t be counted by looking at it, and that’s said before installing, not afterward.

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’s closed. The real screen holds far more; this is the main thread.
- The alert fires
- You open it
- You confirm or dismiss

Who is watching a site where there’s almost never anybody?
44 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.
Why did the line stop?

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’ll say whether IRIS understands it, or not yet.
