The queue tells you when the gates should open
Saturday, seven in the evening, two hours before the concert. In front of the gate, a snake of blue barriers holds seven full lanes of people waiting their turn. The three entrances on the left take the whole flow; the two lanes on the right are set up and almost empty. More people keep arriving across the forecourt from the promenade. IRIS counts how many are waiting, how many go in per minute and how long the last person in line takes to get through.

The figures on this screen are an example from the illustration, not any client's measurement.
IRIS incorporates NeuralPax, a separate licence certified by the Spanish Metrology Centre for people counting, occupancy and crowd-flow control. That the figure is right is guaranteed by a third party, not by us, and that is why it holds up against the regulations in force. The certification covers that measurement — counting people — not the whole product.
How the counting works
Counting is not something you ask for. You draw a line.
A line is drawn across the threshold of the gates: whoever crosses it has gone in, and that is the capacity figure. And an area is painted over the barrier snake, saying how many people are waiting and how long they have been there. Neither the line nor the area can be asked for in words: they are drawn once onto the image and stay there, so a Tuesday figure and a Saturday figure are measured the same way. Counting people is the only measurement we hold approval for from the Spanish Metrology Centre, and it is NeuralPax that does it, a separate licence built into IRIS. We don't claim accuracy. We certify it.

And also, one rule
You decide once. IRIS applies it always.
If
the wait in the queue goes over fifteen minutes or one lane goes unused while another piles up
Then
- alert the gate supervisor with the gate, the lane and how many are waiting
- save the video of the minute the queue stopped moving
- leave the count for that time slot in the event log
The instruction that set it up«Tell me when the wait goes over fifteen minutes, or when one lane empties out while the one next to it piles up.»
What changes
What changes for whoever runs security at the venue
With that figure, the head of security settles three things he now decides by eye: when to open the gates, how many entrances to keep open and how many staff to put on each. If the queue grows faster than people go in, he sees it while it is happening and opens another lane. And the next day he has the whole curve: how many people came, when they came and how long they waited. That is what makes the show start on time.
What people usually ask
Can IRIS's people counting be used to justify a capacity figure?
Yes. Counting people is the only measurement we hold approval for from the Spanish Metrology Centre, and it is NeuralPax that does it, a separate licence built into IRIS. That is why the figure stands up when it is used to measure capacity and manage crowd flow in front of whoever has to check it, which is what the event capacity rules in force require. We don't claim accuracy: we certify it. Everything else IRIS does is not covered by that approval, and we do not present it as if it were.
Does IRIS know who is standing in the queue?
No. IRIS does not recognise faces and does not compare them against any database. It counts bodies crossing a line and bodies inside a drawn area. It knows there are seven hundred and forty people waiting and that they have been there fourteen minutes; it does not know who any of them are, and it does not need to in order to give the figure.
Does IRIS decide when the gates open?
No. That decision belongs to the venue. What IRIS does is put the figures on the table: how many people arrive per minute, how many are waiting and how long they take to get in, event after event. With that curve in front of you, opening half an hour earlier or setting up one more lane stops being a hunch and becomes arithmetic. Whoever signs it off is still a person.

Next step
Who is watching the yard screen when the fight starts?
17 cases: 16 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.
How long before somebody comes down that corridor at four in the morning?
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
What happens outside the framedoes not exist for IRIS. No camera sees the whole world.
So the first thing we do is check what each camera covers and write it down: from here you can understand this, and not that. A dull hour that saves a lot of misunderstandings.
Tell us your problem and we will say whether IRIS understands it, or not yet.
We reply the same working day.
