In my daily work, I do a lot of live streaming, Skype and Google Hangouts. Creating interesting camera angles with webcams has always been a challenge. The straight on, built-in webcam common in laptops and mobile devices presents all sorts of issues: boring camera angles; tethered to the laptop/device; odd light & shadows. Moving the camera off of the device solves a lot of problems and opens up new opportunities. Within two weeks of one another, two new camera options have emerged.
The real test will be Wirecast. If these cameras work natively with Wirecast Pro, they could be game-changers for low-end live streams.
