Thanks for the detail! Here's what we ended up implementing:
We put a webpage window on the dashboard using code from Labview's Example Finder:
see the link here. We created two html files, one for each camera, using the
htmlcode provided by Axis to connect to the camera video feed over http. I used the code from the link above because it removed all text and borders around the video feed. We put a switch in the dashboard code to switch between these two html files within the one webpage window, causing the video feed to switch. The quality is definitely better than that of the feed provided by cRIO processing.
Using the existing VIs, as you suggest, to get the images may be a simpler solution because you don't have to mess with managing html files separate from the Labview dashboard code.
