Maintaining Detection: How SenSource Ensures Reliable Data

At SenSource, we’re committed to making your experience with our people counting system as accurate and effective as possible.

Today, we’re diving into a key feature that helps ensure reliable data: how our system maintains detection of a person once they enter the field of view.

As people counting technology has evolved, so have the expectations—and misconceptions—that come along with it.

For example, some of our customers are familiar with older break-beam sensors. These basic systems used a transmitter and receiver on either side of a doorway, incrementing a count whenever someone broke the invisible beam.

The problem

Break-beam sensors often undercounted groups and overcounted when a person moved back and forth in front of the sensor.

So when break-beams are the last point of reference, it’s natural for customers to worry about those same issues.

But there’s good news—we’ve come a long way.

The solution

Using 3D stereo video technology to monitor traffic from an overhead view, and a sophisticated algorithm, the sensor identifies human shapes based on head and shoulder profiles and maintains detection while the person stays in view.

Why it matters

Maintaining detection means the sensor won’t overcount if someone is pacing or lingering near the entrance. It will only register an in count once the person actually commits to entering—and an out count if they leave.

It also filters out U-turns—people who approach but never truly enter your space.
(If you’re curious, we have a full video about U-turn traffic.)

This is just one of many smart features built into the sensor to ensure your data is as accurate as possible. Because when you’re using foot traffic data to make important business decisions, confidence in your numbers is everything.
