They write, "That’s the purpose of these devices: plug in a camcorder or camera, hit a button and you are live on the Internet. It could be a school play you’re broadcasting to grandparents abroad, a concert friends can’t attend, or a street-level view of a political protest. Of course, you can use a smartphone and one of a handful of apps to broadcast a video stream, but these dedicated devices let you it at a much higher quality. Foremost, you’re not limited by your phone’s camera; you can use a DSLR, a camcorder, or a compact camera with a special lens. Also, given the ability to fine-tune variables like bitrate and compression, you get more control over the file output.

Each device makes it painless, converting the video into an H.264 stream and sending it out over a Wi-Fi or 4G connection."
