cam.AvailableResolutions
check your camera available resolutions
Change the resolution.
cam.Resolution = '630x400';

Correct. On some cameras you can request a resolution, and on some cameras you can request a crop. What you can do with a particular camera can depend on which interface you use for it, which connector and which driver. IP and GigE cameras tend to be more configurable.
