Wireless Infrared People Counting System for Retail Stores
The SensMax infrared people counting system provides accurate visitor counting and footfall statistics for retail stores, helping managers understand how many potential customers enter the store throughout the day. By combining data from each people counting sensor with POS results, retailers can measure conversion, evaluate staff efficiency, analyze promotional activities and plan operations based on real visitor traffic.
Wireless infrared people counters such as the SensMax S1 and SensMax D3 are mounted on both sides of the entrance and powered by long-life batteries. This makes the system ideal for small shops and large retail chains that need a scalable, low-maintenance and GDPR-compliant solution for tracking customer flow.

Why Accurate Visitor Data Matters in Retail
Understanding store traffic is essential for evaluating marketing performance, staff efficiency, customer conversion and store profitability. Infrared visitor counting sensors help retailers see how many customers their stores attract, when peak hours occur and how traffic changes after campaigns or layout updates.
- Measure real store performance – hourly, daily and campaign-based visitor numbers.
- Improve staff planning – align working hours with actual visitor peaks.
- Evaluate storefront impact – check whether new windows or signage influence traffic.
- Compare multiple stores – consistent statistics across the entire retail chain.
- Track long-term trends – monitor seasons, holidays and recurring traffic patterns.
How the Infrared System Works
Each infrared people counting sensor is installed on opposite sides of the entrance at chest level. A transmitter sends a safe IR beam to a receiver. Every time a visitor crosses the entrance and interrupts the beam, the visitor counting sensor registers a count. Bidirectional SensMax D3 models can separate IN and OUT movement to calculate occupancy.
All SensMax S1 and D3 wireless people counters send hourly statistics to the central server via SensMax SMX gateways. Sensor communication ranges vary from 50 m to 800 m, depending on the model. Internal memory keeps up to 25 days of backup data during connectivity outages.

Wireless retail footfall sensors communicate with the gateway and forward statistics to the reporting platform.
Key Advantages for Retail Stores
- Low installation cost – wireless infrared counters require no cabling and install in minutes.
- Long battery life – up to two years of operation on AA batteries.
- High accuracy in narrow entrances – perfectly suited for single-door retail stores.
- Anonymous and GDPR-safe – IR sensors detect beam breaks with zero image recording.
- Offline backup memory – sensor stores data locally if the network is unavailable.
- Highly scalable – economical for chains with dozens or hundreds of stores.
System Components
- SensMax S1 – unidirectional infrared people counting sensor.
- SensMax D3 – bidirectional visitor counting sensor for IN / OUT detection.
- SensMax D3 TS – real-time IR people counter with 5-minute updates.
- SensMax SMX Gateways – LAN, Wi-Fi or long-range receivers for centralized data collection.
Reporting and Integration
Footfall statistics appear automatically in the SensMax reporting platform, which includes more than 20 analytical, statistical and financial reports. Retailers can use cloud reporting or install the software locally. For advanced integrations, all data from people counting sensors is available via API or MQTT for real-time workflows.

Business Impact
With complete visibility into customer traffic, retailers can reduce operational costs, schedule staff based on real demand, evaluate campaign effectiveness and improve conversion. By comparing footfall with POS results, managers can analyze sales per visitor, identify underperforming stores and adjust strategies to increase profitability across the entire retail network.
