I agree that the camera was pretty darn good for my breed too. Of course people blocked it from time to time, and ran in front of it. There is no other option unless the camera is in the center of the ring (which will never happen).
My dog won Best of Winners at our national specialty a few years ago; the video my daughter took was atrocious - the final cut still had so many dogs they were lined up all around the entire ring. You can catch a few glimpses of us but in general, the video is nonexistent. Even spectators couldn’t see.
Having someone’s butt in the camera for 2 seconds is no big deal.
