CameraVision

"CameraVision" outputs the images of the built-in camera and the corresponding sounds from the built-in microphone to an external device such as a projector or a TV monitor. This application can be used similar to a "document camera (overhead projector)" or a "live camera" to project documents, objects, people or scenes onto a large screen. In addition, showing a still image from Photo Albums is possible. A dock/Lighting-connector adapter/cable can be used and the wireless transfer to Apple TV (AirPlay) is also supported.

The following adapters/cables are supported:

- Lightning to VGA Adapter
- Lightning Digital AV Adapter (HDMI)
- Apple VGA Adapter
- Apple Digital AV Adapter (HDMI)
- Apple Composite AV Cable
- Apple Component AV Cable
- Apple TV (2nd generation and later)
