Possible to display 3 video streams with NI IMAQdx?

[gjacob]

Hi, I have 3 Sony cameras that I would like to continuously stream the output from onto the front panel. They are model XCD-SX90CR and are supported by IMAQdx drivers. I am wondering if streaming 3 at a time is possible with a desired framerate of at least 5 FPS but higher is better. Also, I am wondering: if this is possible, what is the best way to run the acquisitions? I considered parallel acquisitions but I am not sure if that would work. I also considered using a sequence, but I really do want it to be fast. Thanks for any insight, this is the first time I've used IMAQdx and it is all foreign to me.

Hi,

There is a simple equation for that:

   XResolution x YResolution x bits/pixel x Frames/sec x # of Cameras  < 800MB/s (1394b)

According the specifications of your camera it should be possible to run three of them a bit faster then 5fps.

And for sure, you can run them in parallel, but I would suggest a powerfull multicore system then.

Alright, thank you Christian!
