LoRaWAN mini AI people counter EU868 battery powered Milesight VS351

The Milesight VS351 is built for people counting in clearly defined indoor passage areas where compact size, wireless installation, and anonymous detection matter. The battery-powered version uses both radar and thermopile sensing to count people in two directions. That makes it suitable for entrances, corridors, transitions between zones, smaller retail entries, office access points, and internal passages where camera-based systems are not wanted.

The practical advantage is the combination of compact form factor and solid counting performance. The sensor is designed for projects that need foot traffic data without the cost and complexity of extensive wiring or video-based counting systems. For operators of office sites, retail stores, side areas, restrooms, or public buildings, this is often the right fit when the goal is to understand usage and traffic levels in a straightforward way.

Radar and thermopile work together to improve detection and handle situations such as U-turns or people moving close together more effectively. At the same time, the detection remains fully anonymous because no personally identifiable image data is created or transmitted. That makes the VS351 useful for projects where privacy needs to be considered from the beginning.

Typical use cases include office entrances, smaller retail access points, passage areas in administrative buildings, side zones, meeting areas, restroom access, and other indoor spaces where traffic needs to be monitored with minimal installation effort. The data can be used to assess occupancy, improve cleaning schedules, compare traffic flow, or trigger simple automation logic.

The battery-powered version is especially relevant for wireless retrofits. It supports NFC configuration, local data storage, retransmission, and Milesight D2D. That makes it practical for projects where stable people counting, low infrastructure cost, and flexible mounting are the main priorities.
