People counter sensor Milesight VS350-868M — wireless IoT visitor counting device (868 MHz)

The Milesight VS350-868M is a compact people counter sensor designed for wireless IoT deployment on the 868 MHz band. It detects and counts visitors using onboard sensing technology and transmits occupancy and traffic data to compatible IoT gateways or platforms. The device is intended for environments where monitoring footfall, occupancy and movement patterns supports operational decisions and space planning.

Advantages

The sensor provides accurate visitor counting with low-power wireless communication at 868 MHz, enabling extended battery life and flexible placement without the need for wired connections. Its compact design simplifies installation in retail, public buildings and facilities where unobtrusive monitoring is required. Data transmission to IoT gateways allows centralized collection and integration with analytics and reporting tools.

Suitable for

• Retail stores for customer footfall analysis
• Shopping centers and malls for traffic monitoring
• Office buildings and meeting rooms for occupancy tracking
• Public facilities and transport hubs for visitor counting
• Facility management and space optimization projects

Key specifications

• Wireless frequency band: 868 MHz for sub-GHz IoT connectivity
• Primary function: people counting and occupancy detection
• Power source: battery-powered with low-power operation (battery life varies by transmission interval and environment)
• Form factor: compact, wall- or ceiling-mountable sensor housing suitable for unobtrusive installation
• Data output: occupancy and visitor count metrics transmitted to compatible IoT gateways or platforms
• Environment: intended for indoor use in commercial and public spaces

How to use

Install the sensor in a position that covers the intended entrance or walkway so that passing people cross the sensor field of view. Pair the device with a compatible 868 MHz IoT gateway or network according to the gateway manufacturer’s instructions, then configure reporting intervals and any integration settings on the platform that will receive the data. Verify detection accuracy by performing test passages and adjust mounting height or angle if needed to optimize counting performance.

Recommendations

Place the sensor above or beside entrances at recommended mounting heights to minimize occlusion and false counts. Choose transmission intervals that balance timely reporting with battery life. For integration with analytics, ensure the receiving platform supports the device’s data format and apply any calibration or filtering offered by the platform to refine visitor counts for your environment.
