Thermal type people counting sensor/ footfall counter
IR based people counting sensor,
Thermal & IR type people counting sensor / footfall counting system
Privacy, cost relative low, while Accuracy not very desirable, and easily impacted by the surrounding environment, not visible
WiFi / BLE (Bluetooth Low Energy) bounded by WiFi / BLE enabled.
Video based people counting camera, people counter, and more accuracy
2D monocular, 3D binocular, 4D type or 3D+ (3D+TOF)
Entry level; but With Acceptable higher accuracy 95%~98.5%;
Very low cost of ownership,
Be born for large-scale commercialized deploying.
Very High accuracy 98~99%, higher costs,
Separate children from Adults
Distinguish shopping carts from human beings; Heat map
4D or 3D+ (3D+TOF) Time of Flight
The most accuracy and the highest costs with the most advanced technology, >99%
