An AI-Enabled People Counter
The advanced people counter excels in bi-directional tracking, offering real-time and reliable data with an extensive detection range. It maintains high accuracy through its sophisticated AI algorithm, which effectively filters out side-by-side and U-turn walkers.
High Accuracy of up to 95%
It ensures reliable and precise data collection with an accuracy of 95%. When counting single-person passages exclusively, the wireless people counter achieves an exceptional accuracy rate of up to 99%. This level of precision allows you to rely on the collected data for critical decision-making confidently.
Multiple Sensors in One
Experience cutting-edge precision with multi-sensor fusion. Utilizing radar to activate, the people counter delivers unparalleled accuracy with an advanced thermopile sensor. Simultaneously, a dedicated temperature sensor ensures the device performs flawlessly within ideal environmental conditions.
Ultra Low Power Consumption
To reduce power consumption during unoccupied nights, users can set sleep periods where the device enters hibernate mode. When the active period begins, the device resumes full operation. The synchronized operation of the radar and thermopile ensures energy efficiency and low power consumption, making it a ESG compliant people counter.
