Q. What is required to use the Windows Hello facial recognition logon in Windows 10?
A. A regular webcam will not work with Windows Hello. Windows 10 features Windows Hello, which provides new ways to authentication using biometrics including facial recognition. Since this is essentially 3-d detection, a camera with a specialized illuminated infrared camera is required.
Two common implementations are the Intel RealSense technology (F200 camera) and the Kinect v2. A number of laptops utilize the F200 camera today and it can also be purchased as a standalone camera as part of a developer kit.
