Does anyone have any experience with dedicated robotic/automated cameras or their venues? I see systems like the Vaddio Wallmount systems that spec Sony Robotic cameras. The cameras seem to be single CCD's. They push them for house of worship and conference room settings, and lecture halls. COuld they provide decent video for concert settings? We have in house video that is horrifically setup and mismanaged, and we are toying with the idea of one of these systems as a replacement. THoughts?
