If you are not seeing video with 4K Pro Webcam and Skype for Business on a laptop with an integrated camera that supports Windows Hello, please try the following short-term fix until a planned Skype for Business software update is available to fix this issue:

1. In Device Manager, click the arrow next to Sound, video and game controllers to expand it.
2. Right-click on the listing for the camera (example: Intel(R)AVStream Camera…)
3. Select Disable.

You should now be able to see video on Skype for Business.
