We talk a lot about sensor accuracy. It’s the main reason customers want to invest in an intelligent 3D people counting system. When you’re using the data to steer major decisions for your business, you want it to be accurate!

You may be thinking, “Don’t all providers offer the same level of accuracy?”

While the sensor is developed with a high level of functionality, it’s the knowledge and efforts of our Support team during calibration that set our sensor accuracy above the competition. The sensor is only as smart as the logic behind it.

After a counting device is installed, our Support team will connect to your device remotely to calibrate the settings. They’ll take a look at the detection area and analyze the scene. Where do guests enter the field of view? Is it an open floor or are there obstructions like tables or shelves? Does this customer want in/out metrics at the door, real-time occupancy, or any advanced configurations?

Considering these questions helps our Support team decide where to place count lines and count zones on the sensor’s back end. They define areas where events are triggered, like a count.

Count Lines

Count lines are the logic to tell the sensor when to count an entrance or an exit count. They are typically drawn at the threshold and create a crossing event whenever a person intersects it. The information that’s captured is a directional count with a timestamp. Then that data is transmitted to Vea for reporting.

Count zones

For more advanced metrics, such as queue length, average dwell time, or occupancy within a defined area, Support will draw virtual count zones on the sensor’s back end.

Lines are used to draw custom count zones. Events are created when people enter and leave the area, and when tracks start or end within the zone. Then the sensor can transmit data to Vea Analytics Software such as occupancy (how many tracks are currently within the zone) or dwell-time (the time between entering and leaving the zone).

The great thing is, one sensor can have multiple count lines and multiple count zones. So a single sensor at the entrance can count ins and outs while also monitoring how many people stand in front of the display near the front door.

The calibration stage is crucial to obtaining optimum accuracy, and we couldn’t do it without our amazing in-house Support team! Be sure to reach out to them if you’re ever making major changes to your entrance, like moving furniture or signage within the sensor’s field of view, so they can determine if your count lines need to be adjusted.
