It can be configured for streaming on all the popular platforms and can capture video from a wide range of smartphones and ANY CAMERA with HDMI out! Perfect for capturing a rough cut of a wedding, then export the captured video to an Adobe Premiere timeline! It's unbelievably functional for almost any video project. An iPad is required to run the free app (available on the Apple App Store).
