Real-Time Radar People Counting for Retail Stores
The SensMax TAC-B radar people counter for retail offers businesses a clear picture of the number of people entering their stores and those passing by. It also helps understand customer behaviour as it can track visitors as they enter, move around, and exit the store, all without recording images. This is then presented in terms of time, day of the week, or in the context of a campaign for quick decision-making.
SensMax TAC-B 3D-W Indoor People Counting Radar sensors are mounted on a wall and cover up to 100 m². They use Wi-Fi to send the data instantly to SensMax dashboards. If connectivity is lost temporarily, the sensors store the data on an internal SD card and sync it automatically when the connection is restored.
Why People Counting is Valuable for Retail Businesses
Radar people counters for retail help businesses understand customer behaviour and trends. They track how many people enter a store and how many walk past the storefront. Retailers can also know when traffic peaks and if a campaign was effective in attracting customers.
This data benefits businesses in different ways:
- Measuring true conversion rate – You can compare walk-ins against passerby traffic and even visitors vs actual purchases.
- Evaluating window displays and storefront impact – You can determine whether added exposure is translating into more store entries by comparing data.
- Optimizing staff schedules – It is easier to align staff hours with actual traffic patterns.
- Improving store operations – You can notice traffic changes in real time and act faster to reduce bottlenecks during busy periods.
- Comparing stores and locations – You can compare data to see what is working in a different location and where there is room to improve.
How the Retail Radar People Counter Works
The SensMax TAC-B 3D-W Indoor People Counting Radar is mounted at approximately 3 metres height on a sidewall or column. It has a 10 m range and a 120° viewing angle, giving it a detection area of up to 100 m².
The radar people counter for retail uses multiple user-configured counting lines and can identify people walking in, people walking out, and others just passing by. It then shares this data via Wi-Fi to SensMax cloud dashboards.
Alternatively, it can export the data via API or MQTT for integration with existing BI tools. When there is no connectivity, the sensor stores data on an internal SD card and automatically syncs it when connectivity is restored.


Installation examples for counting entering visitors and passerby traffic near the storefront.
Ideal for Open-Front Stores and Complex Retail Setups
Most people counters require installation on a ceiling, which may not always be possible in open-front mall units or island-style kiosks.
TAC-B is not restricted by this type of architecture as it can be installed on sidewalls or columns, making it practical for all types of retail stores. A single sensor covers a wide area with adjustable counting lines, reducing the need for multiple devices.

TAC-B radar sensor detects passing traffic in front of the store entrance using non-filming people counting technology.
Turning Retail Footfall Data Into Measurable Business Results
When a business knows how many people enter a store, when traffic peaks, and how the storefront converts passerby exposure into actual walk-ins, it gets a strong foundation for reliable decision-making.
Data from the TAC-B radar people counter for retail is presented as analytics on the SensMax dashboard, allowing a business to align staffing with real demand, measure the impact of campaigns, and identify which locations convert well relative to their foot traffic volume.
In the long run, the business gets a clear picture of its operations and customer trends, making it easy to optimize processes and make prudent decisions.
FAQ – TAC-B 3D-W Radar People Counter for Retail Stores
- Can the TAC-B count people passing by without entering the store?
Yes, TAC-B can count passers-by, as you can configure different counting lines. If you set one in a pedestrian area, it will give you an accurate count of the people who use that path. - How accurate is a radar people counter compared to infrared systems?
A radar people counter is more accurate compared to infrared systems in complex layouts because mmWave tracks full movement instead of relying on simple beam breaks. It also minimizes false triggers caused by objects like trolleys. - Is the system GDPR-compliant?
Yes, the TAC-B people counter for retail is 100% GDPR compliant. It uses radar detection and does not capture images, record video, or store any personal data. It does not have a camera. - How wide an entrance can one sensor cover?
One SensMax radar people counter covers approximately 10 metres, depending on installation geometry and the user’s zone configuration. In most standard retail entrances, a single sensor is sufficient. - Is data available in real time?
Yes, SensMax radar people counters share data in real time via Wi-Fi. It can also be exported via API or MQTT if you want to integrate with third-party platforms.
