Escalators in the concourse
The station concourse with two escalators, one going up and one going down, and a fixed staircase beside them. People are riding up one and down the other. IRIS counts how many pass in each direction; it does not know who they are.

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.
The series, not one figure
One number says nothing. A curve does.

How the counting works
Counting is not something you ask for. You draw a line.
There are two lines, one over each escalator, and each line has a direction: the upper one adds what goes up, the lower one what comes down. If somebody crosses a line against its direction it is logged separately, because walking up the down escalator is a risk, not a traffic figure. And when minutes go by without anyone crossing either line, that time is added up as an escalator running empty. The direction of a line cannot be explained in a sentence: it is drawn as an arrow onto the frame, once, and that is why January's figure is measured the same way as July's.

What changes
What changes for whoever runs the station
The maintenance manager has two decisions on his desk and no numbers to take them with. The first is what time it pays to run both escalators upwards: when a train arrives everyone goes up at once, and when one leaves everyone comes down at once, but nobody knows the exact hour it flips. The second is how many hours a day the escalator turns with nobody on it, which is electricity paid for and wear piling up: that is what sets the shutdown or the on-demand start for the dead hours. With the two lines in place, both questions have an answer by time band. And the against-the-flow count adds a third: if six people a day walk up the down escalator, the direction is wrong at that hour, and it is not the people's fault.
What people usually ask
Can IRIS reverse an escalator by itself?
No, IRIS does not move the escalator: it measures and it flags, and the switching is done by whoever operates the installation. What IRIS brings is the moment and the reason: at 8:20 three times as many people go up as come down, and that shows in the series for every day, not in the impression of one morning. If you want that signal to reach the system that governs the escalators, it is a connection that gets agreed and tested beforehand, not something that appears on its own. We prefer to say it plainly: the figure is ours, the switching belongs to whoever is responsible for the machine.
How does IRIS know the escalator is running empty?
IRIS knows it because it counts absences, not only presences. If the escalator is running and for minutes on end nobody crosses its line, that time goes into a separate counter: escalator turning with nobody on it. At the end of the day there is no impression, there is a figure — so many hours and minutes — and at the end of the month there is a pattern by time band. That is where you see that between eleven at night and one in the morning the escalator has been running for nobody for years, and that is a bill you can cut without touching the service.
Is the person walking up the down escalator identified?
No, nobody is identified: what gets counted is how many times a day it happens, not who does it. IRIS logs a crossing against the direction, with its time, and that is where the record ends. There is no face, no file and no comparison with any database. Nor is the number meant to tell anyone off: six people a day walking up the down side is not a manners problem, it is a warning that upward capacity is short at that hour. It reads as a signal about the installation, not as a list of people.
The real interface, step by step
We won't just tell you. We'll show you.
It is 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.
- The rule gets built
- It goes to every camera
- Published, it watches alone
- And then it fires
Next step
Who sees the sales that never reach the till?
10 cases: 4 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.
Who is watching when the load swings over somebody?
11 cases: 9 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.
And the best part
With two screens you watch.With twenty you look without seeing.
It is nobody’s fault: it happens to everyone. IRIS watches all twenty at once and only interrupts when something deserves a person’s attention.
Tell us your problem and we will say whether IRIS understands it, or not yet.
We reply the same working day.
