Cutting-Edge Sensing with Less Power
VS321 combines PIR motion sensing with an RGB camera and embedded AI algorithms to achieve up to 95% occupancy detection accuracy.
Reporting Mode
VS321 performs occupancy detection at configurable intervals to deliver stable monitoring, making it perfect for daily workstation management.
Detection Mode
VS321 leverages PIR to trigger the camera only upon motion detection, with AI analysing images to determine occupancy. This dual-tech approach ensures accurate detection, enables efficient workstation management, and reduces power consumption for longer battery life.
