Q
Why does the USB 3.0 video output function of XCAM4K series not work on Windows 7 or lower versions?
A
For XCAM4K series, USB 3.0 video output function is implemented by UVC protocol based on ISO transfer. However, Windows 7 or lower versions do not support USB 3.0 UVC output. It can work on Windows 8 and Windows 10. To use USB video output function on Windows 7 or lower versions, users can use USB 2.0 cable or connect USB 3.0 cable to USB 2.0 port on computer. Video output is in MJPEG format, and video output frame rates are the same for USB 3.0 and USB 2.0.
