Real-Time People Counting in Retail Stores
SensMax TAC-B 3D-W mmWave radar sensors deliver real-time retail people counting for entrances and storefront areas – including both entering customers and passer-by traffic. This gives retailers reliable data to calculate true conversion (walk-ins vs. passers-by), evaluate window display performance and understand how many potential customers walk near the store without entering.
Unlike overhead systems that require a ceiling, TAC-B can be mounted on a sidewall or column, which makes it ideal for open-front stores, island-type retail units, kiosks and spaces with complex architecture. The sensor covers wide entrances with a 120° field of view (up to ~10 m) while remaining camera-free and privacy-safe.
Realtime visitor analytics for retail stores based on privacy-safe TAC-B radar sensors.
Why Retail People Counting Data Matters
Retail performance depends on knowing how many people enter the store, how many walk past the storefront, when traffic peaks and how visitor flow changes after campaigns or merchandising updates. With TAC-B, retailers replace assumptions with measurable data, enabling better staffing, smarter layouts and improved marketing ROI.
- Measure true conversion – compare walk-ins against passer-by traffic.
- Evaluate window displays and storefront impact – see if exposure turns into entries.
- Optimize staff schedules – align working hours with real peak traffic.
- Improve store operations – reduce bottlenecks and respond faster during busy periods.
- Compare stores and locations – standardize analytics across the retail chain.
How the Retail People Counting Solution Works
TAC-B 3D-W uses 60 GHz mmWave radar to track movement vectors near the entrance. Direction classification enables accurate IN / OUT counting, while virtual counting lines and zones can be configured to separate store entries from passers-by within a ~10 m range and 120° field of view.
Data is delivered in real time over Wi-Fi to SensMax dashboards and can be exported via API or MQTT for integration with BI tools, dashboards or retail systems. If internet connectivity is temporarily unavailable, the sensor stores statistics on an internal SD card and synchronizes automatically later.

Key Benefits for Retail Stores
- Footfall + passer-by analytics – measure storefront exposure and actual walk-ins separately.
- Wide entrance coverage – one sensor can cover entrances up to ~10 m depending on layout.
- Real-time reporting – live dashboards for operational decisions during peak hours.
- Camera-free and privacy-safe – anonymous radar sensing with no image capture.
- Flexible placement – sidewall or column mounting for open-front and island-format stores.
Installation Options for Stores Without a Ceiling
TAC-B 3D-W is typically installed at approximately ~3 m height on a sidewall, column or structural element using the included adjustable bracket. This enables professional people counting in stores where overhead sensors cannot be installed – such as open mall units, island-format stores and spaces with glass ceilings or complex architecture.
With the 120° field of view, a single sensor can often cover wide or irregular entrances, reducing the number of devices required. Fine tuning of angle and zone setup helps separate entry events from passer-by flow.
TAC-B radar sensor detects passing traffic in front of the store entrance using non-filming people counting technology.
Business Impact
With accurate retail people counting data, chains can allocate staff based on real traffic, improve conversion by optimizing storefront presentation and measure how campaigns affect both passers-by and walk-ins. Long-term analytics reveal seasonal changes, location differences and the real impact of layout or merchandising updates across the network.
FAQ – Retail People Counting, Passer-By Traffic and Conversion
- Can TAC-B count people passing by without entering?
Yes. Virtual zones can be configured to measure passer-by traffic near the storefront separately from store entries. - Is the system privacy-safe?
Yes. TAC-B uses mmWave radar and does not record video or images. - Does it work in open-front stores or island units without a ceiling?
Yes. TAC-B can be mounted on a sidewall or column, which makes it suitable where overhead counters cannot be installed. - How wide an entrance can one sensor cover?
Up to approximately 10 meters depending on the installation geometry and configured zones. - Is data available in real time?
Yes. Data is delivered via Wi-Fi and can be viewed in dashboards or exported via API/MQTT.
