CAM-481

One gate standing idle while the next one jams

Half an hour before kick-off, on the turnstile line. Four full-height gates side by side. Through the first one people walk without stopping. The second has bunched up: half a dozen people crowded in front of the reader. The third is closed, with a member of staff standing in front and nobody going through. The fourth is completely empty: nobody has used it at all. And out on the forecourt, forty-six people wait their turn for the first two.

What this camera gives back

Nobody gets an alert here. Here you get numbers.

31 / minCrossings per minute at the entrance that flows

0Crossings at the unused entrance

3 480People counted on this line

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.

Each entrance has its own line drawn on the floor of the passage, and the one nobody uses has one too: that is the line that gives the zero, and the zero is precisely the figure nobody has today. Over the forecourt there is also a painted area saying how many people are waiting and how long they have been there. A line cannot be described in a sentence, it has to be drawn, and that is why the number is repeatable: the split from one match can be compared with the next without argument. 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.

one entrance goes five minutes without registering a crossing and another entrance on the same line has more than twenty people waiting

Then

alert the entrance supervisor with the idle entrance and the saturated one
save the video of both entrances at the same minute
log how the crossings split between entrances in the event report

The instruction that set it up«Tell me when a gate has gone five minutes without a single person through and the one next to it has more than twenty people waiting.»

What changes

What changes for whoever runs security at the venue

Gaining entry capacity is almost never a building job: almost always it is spreading better what is already there. An empty gate next to a jammed one is money standing still and people piling up in the street. IRIS counts how many people go through each entrance and per minute, and shows which one has room to spare and which one cannot cope. With that, the venue moves one member of staff, opens the one that was closed, and the same crowd gets in a good deal faster. Without laying a single brick.

What people usually ask

Can you gain entry capacity without building anything?

Yes, and it is the usual case. Most venues do not have too few entrances: they have their entrances badly balanced. IRIS counts the crossings at each one per minute and shows which has room to spare, which is jamming and which nobody is using. Moving one member of staff and opening the closed one is usually worth more than any extension, and it can be decided with the event under way.

Does IRIS open or close a gate by itself?

No. IRIS does not act: it counts and it alerts. Opening an entrance, closing it or sending someone elsewhere is decided by the venue, which knows who comes in where and with which ticket. What changes is that the decision is made with the figure in front of you and at the time, not on the feeling that it looked very full.

Doesn't the ticket reader already count the same thing?

No, and that is why it is useful. The reader counts validations; the camera counts people crossing. When the two figures agree, all is well. When they do not, there is an explanation to look for: somebody went through on the same turn as another, a validation opened nothing, or an entrance was left open. The value is precisely in the gap between the two counts.
