Milesight Mini AI Thermopile People Counter VS351-868M PN White-Battery – Thermopile Counter with Radar Detection

The Milesight VS351-868M PN White-Battery is an intelligent, energy-efficient AI thermopile people counter designed for accurate indoor occupancy and movement tracking. By combining thermopile sensing with an integrated radar module (battery version only), the VS351 achieves up to 95% detection accuracy, or even 99% for single-person passages.

It supports bi-directional counting, U-turn filtering, and side-by-side differentiation, ensuring precise detection even in busy traffic conditions. The built-in temperature sensor measures environmental conditions and monitors internal operating temperature for consistent performance.

With LoRaWAN® connectivity and Milesight D2D protocol, the VS351 enables direct, low-latency communication with other devices — even without a gateway. The NFC configuration via a mobile app simplifies setup, while the device’s local data storage (up to 1,000 records) and data retransmission features ensure reliability.

As a battery-powered model, the VS351 offers up to 1.7 years of battery life (SF7, EU868/US915, 25°C, 1000 people/day) thanks to its ultra-low-power design. With its compact housing, flexible mounting options (ceiling or lintel), and IP30 protection, it is the perfect solution for offices, meeting rooms, and smart building applications.
