Hi,
Webcam redirection allows you to use the camera on the remote desktop, but the settings configured on the local client will not be redirected to the remote desktop.
You may try to configure the settings after you remotely login onto the RDSH server. Please ensure that you have installed the same driver of camera as the client on the server. Then you should be able to adjust the settings on the remote session just like you adjust the settings on yout client. However, we cannot ensure that will exactly work as it may also be influenced by the applications that need to use camera.
Hope the information helps.
Thanks,
Eleven
