People Counters Are Obsolete
Why Artificial Intelligence is transforming retail analytics - and why traditional sensors are no longer enough.

When people counting sensors emerged more than 10 years ago, they were a great innovation. For the first time, retailers could measure foot traffic and understand how many people visited their stores.
But like all technology that fails to evolve, they're now outdated.
After talking to more than 100 retail professionals, here are the 5 main reasons they're moving away from traditional counting sensors.
The accuracy isn't what it seems
That 99% accuracy? It's only achieved in empty stores with perfectly distributed customers. In reality, stores are crowded, messy, and busy. These sensors detect shapes, not individuals. And when your business depends on real data, estimates aren't enough.
They only tell you someone walked in. Nothing else.
Did the customer browse the store? Did they show interest in a product? Did they leave because the line was too long? Traditional sensors can't answer these questions - and it's precisely that context that matters for making decisions.
When they fail, you don't notice. But your data does.
Most sensors aren't monitored in real time. Without monitoring, faulty devices keep generating bad data without anyone noticing. 18% fail within the first year. And if you do catch it, fixing it means sending a technician to the store with a ladder during peak hours.
They don't scale. Because of cost.
Deploying hardware across hundreds of stores is expensive: sensors, installation, maintenance. Multiply that across your entire network and you'll find you're investing more in infrastructure than in getting valuable insights.
Want new features? You need new hardware.
That's the business model: you're locked into a system where upgrading means replacing equipment. Like phones that stop receiving updates, your sensors become obsolete the moment a new version comes out. Keeping up means starting from scratch.
Artificial Intelligence and Computer Vision
- No additional sensors - just the cameras already installed
- Full visibility of the customer's journey inside the store
- Behavior, zones of interest, dwell times, and friction points
- Real-time alerts when something requires immediate action
- Continuous software updates - without replacing any equipment
"Retail is changing. And the way we measure it must change too."
