NI does not have any framegrabbers for laptops. They do have drivers for firewire cameras, which work well with a laptop. This solution may be a bit expensive for just recording video, though.
All cameras have a specific depth of field, depending on the lens you attach to them. By using a small aperture on the lens, you can make the depth of field relatively large, but you need more light to take a picture. Lenses with a shorter focal length also have a larger depth of field.
It is hard to recommend a board without more information. How good does the image quality need to be? Do you need a full 30 frames per second recorded? Do you need long term or continuous recording, or just short clips? Chances are you might be able to just use a webcam or dig
ital video recorder and canned software that comes with them.
