Click a menu option - can't figure out hierarchy

I am using Applescript to perform a number of image tasks. I am using my iPhone as the image capture device, however I am using QuickTime Player so I can see what the camera sees before I take the picture. The issue is that I need to close QuickTime Player and re-open it after every so many images.

I have the script accomplishing this right up until the point it displays this menu:

Now, I need it to automatically select the iPhone. I tried having the script simply use the up / down arrows twice and then push return, that works except that QuickTime likes to switch the order of the selections randomly.

Really, I simply need to know how to get the script to select based on name of the device. I will attach a screen shot of the Accessibility screen for that option as well:

Perhaps someone with some more UI experience than I can help me?

Thank you in advance!
