Mini AI Thermopile People Counter

VS351 is a compact AI thermopile people counter designed for indoor entrance and exit applications. It offers high accuracy in bi-directional people counting, enabling effective analysis of foot traffic and efficient space management. Combined with a radar sensor for presence detection, it intelligently schedules the activation time of the thermopile to optimize power consumption. As a Milesight D2D controller, the VS351 seamlessly communicates with other Milesight D2D devices, establishing more possible connections and paving the way for smoother operations.With easy configuration and wireless detection, the VS351 facilitates simple deployment and connectivity.Compliant with the Milesight LoRaWAN® gateway and Milesight Development Platform solution, users can know the number of people in any indoor space and trigger other sensors or appliances easily via a webpage remotely.VS351 can be used in meeting rooms, office buildings, etc.
