Hi i am trying to trigger saving video from a webcam.

 

My current circuit is attached.

 

The top part calcualtes time difference between to signals

The bottom part saves video from webcam.

 

how can i make it so that the bottom part only saves video for a certain time after the trigger from top part?

 

Any help appreciated.

Hello Kitty,

 

I have used a case structure and a timing VI to determine when the code executes and how long for, hope this helps. I have saved the VI into 2009 format, let me know if you need if for any other version.
