P2+ will sometimes be used below as an abbreviation for Phantom 2 Vision+
The DJI Vision App and Extended Features
Unlike most other quadcopters, the Phantom 2 Vision+ uses a smartphone for many functions. The TX itself is used to power and steer the craft, while the smartphone – loaded with the DJI Vision App – adds an impressive array of features. Telemetry is very important when piloting remote vehicles as it lets the operator know the status of battery life, altitude, speed and heading. It also allows full control of the camera – you control when to take video or stills as well as the quality settings. For the beginner, telemetry can be defined as the quadcopter and the ground station (your smartphone) talking back and forth. Such features are not included on many earlier models and are part of what sets the P2+ apart from any similar machines.
