I work for a venue thats talking about purchasing panasonic robocams but wants me to control them with my existing av-hs410 switcher while simultaneously using it as a live switcher. I've heard some bad things about configuring the switcher to control robocams. My preference would be to have a separate robocam controller.
I haven't used the AV-HS410 to control cameras in a while (just demoed it long ago), but I agree that it would be preferable to use an external control. While I recommend Panasonic cameras/controllers, you might also look at PTZOptics as their controller and cameras are very comparable while much less expensive. The cost savings might make the difference in getting a stand-alone controller. With some of that money you save, you might even get the model with NDI included for future-proofing your purchase.
