USB cameras with DirectShow support do not require a "framegrabber" to function with LabVIEW or the Vision Development Module, you simply need to purchase a copy of the NI Vision Acquisition software, see http://sine.ni.com/nips/cds/view/p/lang/en/nid/12892. Note: the NI Vision Development Module and the NI Vision Builder for Automated Inspection include the NI Vision Acquisition Software.

I think what you're looking for is a PTZ camera (pan-tilt-zoom). These are often used in security and web applications.
There is a thread on this forum that discussed this a bit: http://forums.ni.com/ni/board/message?board.id=170&thread.id=291590&page=2
Otherwise, Google "PTZ camera LabView" and you'll see a bunch of hits.
Good luck.
