Starting with iOS 9, you can connect an iOS device via USB Lightning cable to your Mac and receive the live screen on your Mac. mimoLive allows you to use this so you can use the iOS device as a video source. This is useful for recording screen casts of iOS apps or using the iOS device as an external camera.
If you want to use your iOS device as a video camera we build a special iOS app called mimoCam that helps with that.
Setting up the iOS Device Video Source
Once your iOS device is connected to your Mac with a USB Lightning cable the iOS Device Video Source will get enabled and you can drag it to your sources list.
After adding the video source, you will see the iOS devices screen in your video source and can use it like any other video source.
