The Milesight VS121 is an AI-based workplace sensor for monitoring occupancy and utilization in modern work environments, achieving a detection rate of up to 98% thanks to its AI algorithm. The Milesight VS121 is available in two versions: LoRaWAN or POE
Transmit data via LoRaWAN® or Ethernet depending on the application
Based on the standard LoRaWAN® protocol, the VS121 can work with the Milesight LoRaWAN® Gateway and common LoRaWAN® network servers.
It is equipped with Wi-Fi, allowing easy configuration without configuration tools.
With Ethernet transmission, the VS121-P is available for further applications. The VS121-P features extensive serial interfaces such as DI, DO, and RS485 for various scenarios. The VS121-P supports data transmission via HTTP(S)/MQTT(S) for easy integration and enables remote management through the Milesight DeviceHub or the Milesight Development Platform.
The VS121 can be used at workplaces, retail stores, airports, etc.
