Those tutorials give you the ability to display that picture on the front panel, via a picture control or some other method. Take a look at those examples and see if they provide what you need.

Have you downloaded and installed (or installed from disc )NI-IMAQ 3.5.1 when you install this package you have to select that you want LabView support. Once that is done you will have the example code <LabView Directory>\examples\IMAQ\IMAQ High Level.llb\HL Grab.vi. This VI will allow you to grab a live image with the 1409 and display it on the screen. It sounds like you are wanting to detect motion in the live video. Is this your intent?

Sorry my english Thanks for help There is no built in motion detection with NI-IMAQ, you would have to purchase and develop a motion detection algorithm using the IMAQ Vision Toolkit ($2500 developer package plus $295 per seat liscense). I don't know if this is cost effective for you and your application. I have used the ActiveX control VideoCapX from www.fathsoft.com ($79 developer package plus royalty free distribution) which has a built in motion detection algorithm. Of course you won't be able to use the 1409 as your video input device, you'll have to move to a simpler and less costly board like the WinTV-Go-Plus or any of a million other WDM video input devices. I've used this ActiveX control in LabView and had no problems. Let us know which software package you choose. Chris Quote Link to comment

Sorry the english, and thanks for the help you are give me. Try this, I've modified your VI to work. You realize you can't display video from the 1409 card using this activeX control right?
