FaceTime is an application that allows two Apple device owners to make video calls to each other over a WiFi or cellular phone connection. Apple devices that can use the FaceTime application include iPhones, Macs, iPod Touches and iPads. Users who have activated the FaceTime application on their devices can initiate video calls with compatible contacts by either clicking the FaceTime button by contact entries or by initializing the program using Siri.
Once a user initiates a FaceTime video call, the contact receiving the call simply chooses to accept it to begin the video call. Video calls made on FaceTime can also be oriented in either landscape or portrait view. Apple devices with built-in cameras, such as the iPad or iPhone, use its native front camera for FaceTime, as it has been designed to take into consideration both focal length and field of view. Users can also share what is in the view of the device's back camera by choosing the option inside the FaceTime application.
Apple device owners can set up FaceTime by going to their device's Settings option and turning on the application option. Users are required to use their Apple IDs to log into the FaceTime application.
