The usual definition of a webcam is a low cost camera with a USB interface, so by that definition, not using just the cRIO 9072 (
this page notes using an external laptop because the cRIO 9072 lacks a USB host port). You could potentially use a
network camera like the ones we use in FIRST, but you're looking at almost an order of magnitude higher cost in a lot of cases.
If all you're trying to do is detect the presence of something, it seems like there could be easier ways to do so. Depending on the thickness of the part, something like an infrared range finder might do the trick, else it sounds like all you really need the camera for is detecting a change of color in the scene it will be viewing (you say it's a simple machine vision problem, which suggests to me that you're not trying to do shape recognition or something) to detect whether the component is in the mold. If this is the case, something like a
color sensor seems like it would work equally well.
Sort of on the same simplification train of thought, it makes me wonder why you need something as complex as a cRIO to just detect presence of an object. (Unless it's already in the system for something else, I suppose.) But I don't have any experience in manufacturing process engineering, so I'm not sure as to specifically what requirements you might have.
