SensMax S1 Wireless People Counting Sensor
The SensMax S1 wireless people counting sensor uses an invisible infrared beam to detect visitors crossing an entrance or corridor. This IR people counter is battery-powered, camera-free, and designed for fast deployment in retail stores, libraries, offices, and public facilities. It delivers accurate footfall metrics without complex installation.
How It Works
The SensMax S1 creates a narrow infrared beam across the passage. When a person breaks the beam, the people counter records the event and stores it locally. At regular intervals, data is transmitted via the SensMax SMX gateway to the reporting portal, where managers can access dashboards, alerts, and exportable reports. Built-in memory preserves hourly statistics during short outages, ensuring visitor counts are not lost.

Installation & Privacy
Installation of the wireless visitor counter is quick and cable-free: mount the transmitter and receiver on opposite sides of the passage with tape or a bracket, align the infrared beam, insert AA batteries, and pair the device with the SMX gateway. The system is fully anonymous and GDPR-compliant — no cameras or personal data are used, only simple entry counts.

Business Impact
Deploying the SensMax S1 people counting system helps managers make smarter operational decisions. Reliable visitor metrics support staff planning, marketing analysis, and service quality improvements without the complexity of camera-based systems. Automated dashboards and scheduled reports provide clear insights into visitor flows across days, weeks, and months. This allows businesses and facilities to optimize resource allocation, evaluate campaigns, and identify underused areas for better utilization.
Example in Action
A national retail store network rolled out SensMax S1 counters across dozens of branches, where staff mounted the sensors at entrances within minutes thanks to the wireless, cable-free design. All devices were live the same day, and dashboards quickly revealed clear differences in traffic patterns between weekday mornings, weekend afternoons, and promotional campaigns. Managers used these insights to adjust staffing schedules to peak hours, allocate marketing budgets to the highest-performing stores, and redesign promotions for underused entrances. The system even uncovered hidden trends, such as strong lunchtime traffic near office districts, which enabled targeted offers that boosted sales. As a result, the chain improved customer service, reduced queues, and achieved a measurable increase in marketing ROI across multiple locations.
