Overview
VS121 overview
Overview
The VS121 is an AI workplace occupancy sensor that shows how offices are really used. It detects people across meeting rooms, open offices, and corridors so teams can plan space with confidence.
Detection
AI algorithms deliver up to 95% accuracy and filter out U-turn movement to avoid double counting. The sensor reports presence, people counts, and dwell time for each area.
Coverage
One unit covers a wide field of view with up to 16 customisable regions, so it adapts to irregular layouts. Standard mounting suits 2.5 m to 4 m ceilings, with a high-ceiling version for taller spaces.
Privacy
Detection is fully anonymous, with no personal data captured, which supports GDPR compliance. Up to 8 privacy masks let you exclude sensitive areas from analysis.
Integration
Data travels over LoRaWAN, with Milesight D2D for direct device-to-device triggering without a gateway. Standard protocols like MQTT, HTTP, and Modbus connect it to BMS and third-party platforms.
Installation
The compact ceiling-mount body sets up quickly, with Wi-Fi configuration and a Type-C connection. It draws low power and runs on a simple 5VDC supply.

Applications
VS121 applications
Office
In open-plan offices the VS121 tracks zone occupancy and people flow across the day. Teams use the data to optimise desk layouts and support hybrid work.
Meetings
For meeting rooms it reports headcount and dwell time to reveal real usage. This cuts ghost bookings and improves room scheduling.
Planning
Facilities teams base workplace planning on actual usage instead of assumptions. Zone and time data guide redesigns and capacity decisions.
Automation
Real-time occupancy feeds building systems over LoRaWAN or D2D. HVAC, lighting, and ventilation adjust to how spaces are actually used.
Retail
In retail spaces the sensor measures foot traffic and high-occupancy areas. Bi-directional counting supports layout and staffing decisions.
