Double-station examination refers to the use of two cameras to shoot the interview scenes of candidates from different angles at the same time to meet the requirements of double-station examination. Online exam cameras can't point at each other, they must point at themselves. Take a clear picture of your hands and desktop. Otherwise, you will be invalidated because the cameras are monitoring you one by one.
The online exam camera is basically ok for yourself and the side exam, but the camera only plays a supervisory role.
