What is the problem that the video conference camera can't collect images?

For the problem that the local image cannot be collected from the image in the application process, the user can start from three aspects:

1. Check that the camera is connected correctly. In the actual installation process, due to the negligence or misunderstanding of operators, such problems often occur;

2. If the acquisition card is used, check whether the acquisition card works normally or whether the driver of the acquisition card is abnormal. If the acquisition card driver is abnormal, update the lower acquisition card driver, and then check whether the system is occupied by other programs, mainly for desktop software terminals;

3. Check whether the video input device is selected correctly. This problem is also caused by the negligence of many installers.
