Used mimoCam for iOS?
Developer’s Description
mimoCam enables the use of the iPad or iPhone connected to a Mac via Lightning cable to work as an external camera for the live switching app mimoLive on the Mac. In contrast to other camera apps, mimoCam doesn't show controls on the screen, giving you a clear picture.
Double tap on the video switches from front to back camera and back.
mimoCam also wirelessly transmits device orientation data to mimoLive on the Mac to support the creation of video screencasts showing the device in 3D space.
