I'm adding some HD PTZ cameras to a large meeting space primarily to produce multi camera coverage for live streaming and archive recording. I am really looking for feedback on units with the best video quality and overall performance. I've been looking at both the Panasonic HE40-SDI and Vaddio Roboshot 30-SDI. These cameras would be used both with the streaming capability and SDI connections. I've seen shootouts between some of these PTZ units with a wide range of video performance despite similar specs. Anyone with specific experience with these units and their performance would be appreciated. I'd love to hear your opinions.
