    I have a simple test Form with just the RadWebCam control on it. When you first open the form, the camera runs at about 10-15fps. Once you take a snapshot it seems to move up fps.(v4.0.30319 - Win10, I7vPro, 16Ram)

    Why does it shut the camera off every time you take a snapshot? How can I use it to capture multiple images one after another if it shuts the camera off and displays the image in the viewer after every snapshot?

    Hello, Daryl,

    By default, when you take a snapshot, a preview of the image will be shown. To disable this, set the PreviewSnapshots property to false.

    As to the frame rate, I am not sure how exactly you setup the RadWebCam according to the brief information. However, note that you can chose to disable the auto start option and initialize it with a certain camera device and a specific MediaFoundationVideoFormatInfo considering its FrameRate value. The following help article demonstrates how to initialize programamtically RadWebCam 

    I hope this information helps. If you need any further assistance please don't hesitate to contact me.
