People Counter: Cellular NB-IoT Wireless Sensor

The IMBuildings NB-IoT Indoor People Counter is a plug-and-play, battery-powered sensor engineered to transform raw foot traffic into actionable business intelligence. Utilizing direct cellular communication and bi-directional active infrared technology, it delivers real-time visitor analytics without requiring local gateways or complex IT infrastructure—all while maintaining full GDPR compliance.

How It Works

The sensor system projects horizontal infrared beams across doorways or corridors up to 8 meters wide to detect pedestrian movement. It accurately distinguishes between incoming and outgoing visitors, automatically packaging directional count data into secure UDP packets and streaming them directly to cloud platforms via standard NB-IoT cellular networks.

Installation & Connectivity

Engineered for rapid deployment, the device features a true plug-and-play setup completed in under 10 minutes. Simply insert a Nano SIM card along with AA batteries, mount the compact enclosures across an entrance, and configure local network settings via NFC using a smartphone. Operating on native NB-IoT (Band NB1), it functions completely independently of local Wi-Fi or Ethernet networks.

Key Features & Strategic Advantages

• Direct Cellular Connectivity: Transmits data via NB-IoT (UDP protocol) using a standard Nano SIM card, completely eliminating local gateway requirements or network integration delays.

• Bi-Directional Infrared Detection: Tracks separate IN and OUT traffic streams across passageways up to 8 meters wide.

• 100% GDPR Compliant: Measures visitor flow metrics reliably without capturing video streams, images, or personal identifying data.

• Rapid 10-Minute Deployment: Cable-free architecture allows effortless mounting without specialized technical tools or structural modifications.

• NFC Configuration: Fast, wireless configuration of device parameters and network connection settings via any NFC-enabled smartphone.

• Long Battery Longevity: Powered by two standard 1.5V AA batteries, delivering approximately 1 year of continuous operation.

Applications & Real-World Use Cases

• Retail Chains & Showrooms: Gather real-time footfall metrics across dispersed store locations without requiring access to local store networks.

• Public Buildings & Venues: Monitor real-time occupancy and flow patterns across municipal facilities, museums, and public libraries.

• Hospitality & Events: Measure foot traffic in hotel lobbies, conference centers, and dining halls to optimize staffing and resource deployment.

• Commercial Real Estate: Analyze entrance and exit activity across office towers and shared multi-tenant properties.

Business Impact

By combining direct cellular connectivity with instant cloud integration, the IMBuildings NB-IoT People Counter allows organizations to deploy foot traffic analytics across remote or multi-location facilities in minutes. It eliminates configuration delays and local network dependencies, significantly reducing operational costs while providing facility managers and retailers with instant, data-driven visibility into customer traffic trends.
