Description

The Milesight VS351 is a sophisticated, compact people counter engineered for precision monitoring of indoor entrances and exits. By integrating thermopile technology with a radar sensor, the VS351 identifies human heat signatures and movement to provide reliable bi-directional "In/Out" data. This hybrid approach allows the device to intelligently schedule its thermopile activation, significantly reducing power consumption. Designed with a privacy-first philosophy, the sensor processes all data locally and transmits only anonymous statistics over LoRaWAN®, making it ideal for offices, retail, and public spaces.

Intelligent Entrance Analytics

Advanced AI Logic Filters out non-human heat sources and optimizes detection based on mounting height and target speed for up to 90% accuracy.
Peer-to-Peer Automation Features Milesight D2D support, allowing the sensor to directly trigger other IoT devices like lights or fans without gateway latency.

Smart Building Scenarios

• Workspace Efficiency: Track meeting room utilization and occupancy rates to optimize real estate costs.
• Retail Analytics: Understand store traffic patterns and peak hours to improve customer service and staffing.
• Energy Savings: Integrate with building management systems to automate lighting and HVAC based on real-time footfall.
