Accessing a USB capture card

[KD5PFF]

Hello,

            I am trying to access a USB capture card with labview so that I can watch the video on my computer screen. Eventually I would like to be able to record the video. The idea is to build a digital video recorded that detects motion and then records the video of that motion. I.E. a motion sensitive security camera. For simplicity I want the camera to be controlled by X10 stuff, so it only comes on when it sees motion… then the video gets piped into labview and is only recorded when the image shifts from static to an actual picture. The system works with the exception of the labview stuff. Unfortunately I'm still new to labview and I am not sure where to start. But as this is a student copy given to our class, I can not afford to buy cards or more software… so I have to find a work around for that…. Thanks for the help.

Hey Alex,
    I'd love to help you find a resolution to your problems, but I need more info about the specifics of your problem.  What part of LabVIEW is not working correctly?  How are you calling the driver for the USB capture card?  Could you possibly post snippets of your code, or tell us what you have tried that has worked?
