To me, the new SlingStudio is one of the most innovative products shown at NAB2017, and i'm lucky to have a set to review prior to their official release! I've been a big fan of Live Switching and Live Streaming for a few years, but it's been out of reach for many small production teams. Now SlingStudio is making it easier and simpler to offer Multi-Cam Live Streaming.
With SlingStudio you can stream a video feed from any camera (with HDMI out), or install an app on iOS and Android Smartphones and use those devices to stream video back to the SlingStudio Wireless Hub. Once you have all your cameras sending a video feed to the SlingStudio wireless Hub, with an iPad you can then see all of the feeds (up to 10 feeds) and live switch between them.
You can choose to record your Live Switch Program to an SDXC or with an expander you can use an external USB drive. You can also choose to record each feed independently to edit later. The wireless hub as an HDMI input if you want to connect a single camera directly, and there's even a dedicated Audio Line In so you can pipe in a clean audio feed.
To stream an HDMI feed, you can get an optional CameraLink adapter which means you can use cameras like your Panasonic GH4, or Sony A7sII, or even a GoPro (anything with HDMI out). Once you have your camera feeds and recording media setup, you can even opt to Live Stream to a service like YouTube or Facebook, etc.
The SlingStudio Wireless Hub can be battery powered, so you can truly Live Switch + Live Stream from any location - completely wirelessly. I'm currently working on a video about this product, but if you have questions or comments right now, leave them below.
