People counter: measuring footfall, and the number it can't give you
A people counter (or footfall counter) measures how many visitors enter your store. It is the denominator of conversion, and the first thing any physical-retail team should measure. This page covers how counters work, how to choose one, and where footfall stops being enough.
How people counters work
The common technologies are infrared beams at the door, overhead thermal or 3D sensors, and video cameras with AI. Each trades off accuracy, privacy and cost: beams are cheap but miss groups, thermal is more accurate and privacy-friendly, video is the most capable but the most sensitive.
Whatever the method, the output is the same: a count of how many people crossed the threshold, over time.
Footfall is only half the equation
Footfall matters because it is the denominator of conversion: sales divided by visitors. Two stores with identical traffic and very different conversion are telling you something important, but the counter cannot say what. The gap between them lives inside the store, in the interaction, exactly where a door counter stops.
A footfall counter vs Cognifyze
| Footfall counter | Cognifyze | |
|---|---|---|
| What it measures | How many people entered | What happened once inside |
| The question it answers | How many | Why they left without buying |
| Scope | Traffic at the door | Every sales interaction |
| What you get | Visitor counts and trends | Daily coaching per manager |
A counter tells you how many walked in. Not why they walked out.
Footfall is essential; without it you cannot compute conversion. But a count at the door stops exactly where the sale begins. Two stores with the same traffic and very different conversion differ in one place a counter cannot see: what happened in the interaction.
Cognifyze measures that. AI evaluates 100% of sales interactions across your network, with consent and no shopper identification, and returns daily coaching per manager. Footfall tells you how many; we tell you why.

People counter FAQ
What is a people counter?
A people counter, or footfall counter, is a device that counts how many people enter a store or area, using technologies like infrared beams, thermal sensors or video with AI.
How do people counters work?
Common methods are infrared beam breaks at the door, overhead thermal or 3D sensors, and video cameras with AI. Each trades off accuracy, privacy and cost.
What is a good retail conversion rate?
Conversion is sales divided by footfall. What counts as good varies widely by category and format, so your own trend over time matters more than an absolute benchmark.
What does footfall not tell you?
It tells you how many people entered, not what happened inside: whether they were greeted, helped or sold to. Two stores with identical traffic can convert very differently for reasons a counter cannot see.
How is Cognifyze different from a people counter?
A counter measures traffic at the door; Cognifyze measures the sales interactions inside, with AI, and returns daily coaching, the why behind your conversion rate.
