The Milesight VS121 High Ceiling is a professional AI occupancy sensor designed for accurate and fully anonymous people counting in high-ceiling indoor environments. With up to 95% counting accuracy, it provides reliable data for space utilization, visitor flow analysis, and operational optimization.
The embedded AI detects movement direction, dwell time, and people flow within up to 16 customizable detection regions. Smart U-turn filtering prevents redundant counting by excluding individuals who do not actually enter a defined area.
This version is optimized for installation heights between 5 m and 7 m, making it ideal for:
Shopping malls and large retail spaces
Airports and transport terminals
Industrial halls
Sports arenas and event venues
Large lobbies and atriums
With a field of view of 129.4° horizontal and 68.4° vertical, the sensor is tuned for elevated mounting positions while maintaining reliable detection coverage.
Communication is handled via LoRaWAN on 868 MHz (EU868). No personal image data is stored or transmitted. Detection is 100% anonymous and fully GDPR compliant.
Designed for ceiling mounting, the VS121 High Ceiling integrates seamlessly into large-scale smart building deployments.
