One of my projects (still on the back burner at the moment, but slowly 
progressing nonetheless) is a DIY pick-and-place machine for doing small-run 
electronics. It uses standard VGA-quality  USB webcams (such as the type that 
you can get off of eBay for under $10 each… often under $4) to do the 
component-detection machine vision; and I do have the video input section of 
the project seeing the webcams with AVFoundation.

So if that’s the kind of camera in question… yeah, it works.

:-)
