Filson. If you're looking to acquire images from a webcam to use with NI Vision, I recommend using an IEEE-1394 camera with our NI-IMAQ for 1394 driver. It will be a lot easier and cheaper than using one of our digital frame grabbers with a USB webcam. Just make sure the 1394 webcam sends uncompressed data. Our driver can't read compressed mpg files, which is why USB webcams don't work and why we currently don't have a driver for them like we do with Firewire.
