VS121 AI Workplace LoRaWAN Sensor People/Object Detection

The Milesight VS121 AI-powered sensor utilizes anonymous people counting data to provide comprehensive insights into workspace utilization patterns and occupancy analytics.

• Anonymous Detection
• Large Detection Area
• 95% Recognition Rate
• Custom Detection Region

Anonymous Detection

Object detection operates without facial recognition technology – no personally identifiable information is collected, stored, or transmitted, ensuring complete privacy protection.

Superior Recognition Performance

Moving objects are accurately classified as human or non-human with a recognition rate achieving up to 95% accuracy for reliable occupancy monitoring.

Comprehensive Detection Coverage

A single unit provides coverage for up to 5 meters radius (or 6 × 8 meters in rectangular configuration) when installed at 3 meters height, ensuring extensive area monitoring.

Flexible Detection Zones

The VS121 enables mapping of up to 12 custom regions with configurable detection parameters for each zone, providing tailored monitoring solutions.

Streamlined Configuration

• Wi-Fi connectivity for device setup
• USB Type-C power and configuration interface

Note: Wi-Fi functionality is exclusively for device configuration and can be disabled after setup.

LoRaWAN® Technology

All data transmission utilizes LoRa technology for secure, long-range communication. The AI Workplace Sensor does not store or upload images, maintaining privacy integrity.

Compatible with industry-standard LoRaWAN® gateways, providing communication range up to 15 km in rural areas and 2 km in urban environments.

Milesight IoT Cloud Integration

• Regular people counting data reporting
• Interactive collaboration with various Milesight sensors
• Android & iOS applications for comprehensive device management
