People Counters
Benefits, Buying Guide & Best Practises

What are people counters

People counters are essentially any type of device that counts the number of people walking in and out of a certain specified area.

While people counters started out as a simple, manual clicker in the hands of a doorman, they have quickly evolved to become complex machines capable of generating large amounts of in-store data around customer behaviour, visitor demographics, store layout, staff performance and marketing effectiveness.

What’s the reason for the sudden surge in popularity of people counters?

Well, the credit partly goes to pure play online retailers for showcasing the incredible power of customer behaviour insights in boosting sales and revenue. Whenever there is a drop in the conversion rates of an Ecommerce website, it's fairly easy to find the root cause; thanks to in-depth website analytics and customer data available to online retailers. But brick and mortar stores have it tougher when it comes to pinpointing the reason for drop/spike in sales.

Most of the major offline retailers are now investing in advanced people counters to level the online-offline playing field and access the same level of in-depth data as ecommerce brands to understand and optimize store conversion and sales.

Evolution of People counters

While people counters have been in existence for more than 20 years, they were not successful in providing useful insights due to data inaccuracies and technological limitations. But all of that changed in recent years and the latest people counters boast of more than 95% accuracy and the ability to offer critical insights like product preferences of customers, visitor gender and age and comprehensive footfall analytics .

How People Counter Benefits Retailers

For many years, Ecommerce brands enjoyed a major advantage over brick and mortar stores - massive amounts of customer data. In many ways, people counters has helped offline retailers to level the playing field by offering in-depth customer data like customer demographics, product preferences, purchase history etc.

1Boost Sales & Conversion

People counters empower offline retailers to increase their sales and conversion through a combination of several factors like improving store layout using heatmap data, understand customer preferences based on dwell times, personalize product offerings based on customer age and gender and effective staff allocation around store peak hours.

2Optimize Staffing and Labour Cost

Rising labour costs is a major concern for offline retailers in both developed and emerging markets. People counters help retailers to understand optimize labour costs by offering store conversion ratios and peak hour analytics. Store conversion ratio is a critical metric for retailers as it offers insights into the effectiveness of their sales staff.

3Offer a Personalized Customer Experience

Today's Connected Customers are used to highly personalized brand interactions in the digital world. On the other hand, offline stores have struggled to personalize customer interactions due to lack of customer data and behaviour insights. People counters can help brick and store retailers to bridge this 'personalization gap' through in-depth customer data like gender, age, product preferences and past purchase behaviour.

4Measure Marketing Effectiveness

Previously, retailers were left in the lurch with regards to the effectiveness and engagement levels of their marketing campaigns. AI-powered people counters measure the effectiveness of marketing campaigns by monitoring spike in footfalls, dwell times near specific products and overall conversion ratio for a promoted product.

Types of People Counters

While they vary in shape and size, they typically use one of the following technologies :

Thermal Imaging

Thermal imaging systems use heat-sensitive sensors to count visitors using embedded technology. They are highly unreliable due to susceptibility to weather conditions and humidity.

check_circleMulti-directional counting

check_circleWide coverage

check_circleGood accuracy


errorAccuracy is affected by weather and humidity

errorLower field of vision compared to video counters

errorVisitors need to be in motion for the sensor to capture the signal

errorLow demographic accuracy

Infrared Beams

These people counters use a horizontal infrared beam directed across an entrance to count visitors whenever the beam is broken. It is widely considered as highly inaccurate due to variations when multiple visitors entering the store, and inability to differentiate entering or exiting the store

2D Video People Counter

These are video-based counters that use a camera to count the number of visitors entering or exiting a store. While more accurate than thermal counters, they have a major flaw - the inability to distinguish between people and objects

The AI-powered 3D counters are the most accurate of the lot due to their ability to function even under low-light conditions and ability to clearly distinguish between objects and humans.

Choosing the Right People Counter

The primary criteria you'll need to consider when choosing a people counter is accuracy; once you have shortlisted people counter manufacturers with 95% or greater accuracy, here are the other factors you'll have to consider before making the investment.


From simple visitor tallying to generating complex customer behaviour data, people counters offer a wide range of capabilities - therefore it's important to finalize a set of business goals before shopping for a device. Do you need a people counter to help you restructure the store layout to maximize conversions? Or do you intend to understand staff performance? Or maybe you want to understand your visitor age and gender to optimize your store inventory. These are some of the questions you will need to answer before choosing a people counter.

Type of

Opt for a horizontal infrared people counter only if your establishment has a narrow entrance. Also, if you have swinging doors, make sure they swing out only to one side to prevent them from blocking the infrared beam. Larger stores with a wider entrance should always opt for an overhead thermal or video counter.

Type of

Store Size &

The store size and layout will determine the number of devices required. For large retail stores and malls, it's recommended to go with video counters as they offer wider coverage per device and thereby minimizes the total number of required devices. A thermal or infrared people counter will suffice for smaller format stores.

Easy Integrations
with Existing Systems

Several retailers prefer to integrate people counters with their existing marketing cloud and loyalty program platform to provide additional visitor data and customer analysis. A CRM integration also gives you a 360-degree view of the customer journey - from window shopper to buyer. Try to ensure that the people counter you finally choose supports these integrations.

Dashboard &

While the hardware is vital, retailers should also take into consideration the report generation and analytics capabilities of the manufacturer. Unless presented as clear, actionable insights, the data generated by the people counter will be rendered futile. An ideal people counter should offer clear insights around store power hours, store-wise comparison of real-time visitor traffic and also suggest staff targets based on traffic and conversion data.

Installation &
After Sales Support

Advanced people counters are complex devices so it's imperative to choose a vendor that offers fast installation and remote diagnostics capabilities. This will ensure constant uptimes and offer better data accuracy.
