MINICOURSE Visitor counting: How do you know you have counted correctly? (part 3/3)

HOW DO YOU KNOW YOU HAVE CALCULATED CORRECTLY?
To get a good result, you first need to ask yourself the question: What do I want to measure and what question do I want to answer? Is it how many visitors you have, how they move, or something else? The answer to this question is central to finding the best location for the sensors.

If you are a business that charges admission, you probably know well how many and when your customers come and then the behavior of customers after they pay the admission is more important, for example museums and amusement parks. If you instead have a store where your customers come and go, the number of visitors becomes more important.

Once the sensors are placed, you need to calibrate them. This is easily done with an app where you count your visitors yourself for a few minutes, so that the sensor gets a fact to relate to. This allows the sensor to calculate how many people are around it, even if they represent more or fewer MAC addresses and how far away from the sensor they are.

In addition, the same app can be used to ensure in the future that the sensor's calibration is still relevant.
