SensMax TAC-B 3D-W Indoor People Counting Radar

The SensMax TAC-B 3D-W is a indoor radar counter for real-time people counting, occupancy monitoring, and visitor flow analysis in shops, offices, libraries, museums, and public facilities. It uses advanced mmWave radar technology instead of cameras, so it works in any light conditions, including shade, glare, or complete darkness. This makes the sensor a reliable and fully privacy-safe option for indoor environments that require accurate data without video surveillance.

Camera-free people counting radar detects direction and speed indoors for instant footfall and occupancy statistics in a shopping mall.

How It Works

The TAC-B 3D-W uses a 60 GHz mmWave module to track movement vectors and classify people as IN or OUT. The device can draw up to five virtual counting lines and zones inside its coverage area, which reaches up to 10 m in distance, 120° in angle, and about 100 m² in total surface. All counting results, occupancy levels, and dwell times are transmitted over Wi-Fi to online dashboards in real time, giving facility managers accurate insights into how spaces are used. Data can be integrated into existing building systems or exported via API, MQTT, and webhooks for maximum flexibility.

Installation & Privacy

Installing the TAC-B 3D-W is quick and flexible. The sensor can be mounted on a sidewall or indoor structure at about 2.5 m height, where it provides a clear view of entrances, aisles, or rooms. Once connected to power, it joins the building’s Wi-Fi network, supporting open, WPA2-PSK, hidden SSID, or WPA2-Enterprise security modes. Detection is anonymous: no filming, no personal data, no storage of images. This ensures full GDPR compliance, making it suitable for workplaces, retail stores, offices, washrooms, and public buildings where privacy protection is a must.

Key Technical Advantages

The SensMax TAC-B 3D-W offers several important benefits compared to camera-based systems and traditional IR counters. It is designed for indoor use and provides accurate people counting in almost any condition, without the need for extra lighting or special placement. Its radar technology makes it ideal for spaces that require precise counting and reliable occupancy statistics while ensuring full privacy.

• Indoor-tuned radar — stable performance in all light conditions, including complete darkness.
• Flexible line/zone setup — up to 5 configurable counting lines or zones for entrances, aisles, or specific areas.
• Movement intelligence — tracks IN/OUT direction, number of people inside, and dwell or occupancy times.
• Wi-Fi connectivity — secure real-time transfer on standard or Enterprise networks.
• Open integrations — API export, MQTT, and webhooks; optional email or Telegram notifications.
• Low-maintenance operation — sidewall mounting, compact size, no lenses or cameras to clean.

Real-World Applications

The TAC-B 3D-W can be used in a wide variety of indoor projects. By combining real-time people counting, occupancy monitoring, and privacy compliance, it helps organizations make smarter decisions about how to manage facilities, staff, and services.

• Retail entrances — measure visitors entering and passing by to analyze conversion and plan promotions.
• Shopping malls — track occupancy of areas and adjust cleaning, staffing, or HVAC according to footfall.
• Offices & meeting rooms — monitor space utilization to optimize layouts and reduce energy costs.
• Libraries and museums — gather automated visitor statistics for funding, event planning, and exhibit evaluation.
• Washrooms — use real-time visitor counts to trigger cleaning schedules and maintain hygiene standards.
• Advertising screens & info-kiosks — count how many people stop in front of digital signage or kiosks to measure engagement and optimize placement.

Business Impact

With live radar counts, managers can see exactly when and where people are present indoors. This allows cleaning teams to work only when areas are used, staff to be assigned to real peak periods, and building systems such as heating or ventilation to adjust according to actual occupancy. Occupancy limits can be enforced automatically, while Wi-Fi connectivity ensures data goes directly to dashboards and alerts without manual effort. All insights are provided anonymously and camera-free, keeping GDPR compliance at the core of every project.

Example in Action

In a retail store, a TAC-B 3D-W sensor was mounted at a wide side entrance. With its 120° field of view and support for multiple counting zones, it simultaneously measured people entering the store and those just passing by. The results helped management compare true conversion rates, adjust staff shifts for evening peaks, and reduce checkout queue times — improving both customer experience and operational efficiency.

In a shopping mall, TAC-B 3D-W sensors were installed above digital advertising screens. The radar detected how many people actually stopped in front of each display, not just those walking by. With this data, the mall compared engagement across different locations, adjusted ad placements, and provided advertisers with clear visitor statistics to prove campaign effectiveness.
