The Phantom 4 Pro from DJI boasts a 3-axis-stabilized gimbal camera with a 20MP, 1" CMOS sensor capable of shooting up to 4K/60fps video and well as photo bursts at up to 14 fps. The hull has been updated from the previous Phantom 4, now featuring magnesium alloy construction for increased rigidity and reduced weight. The FlightAutonomy system adds dual rear-vision sensors plus infrared sensing for a total of five directions of obstacle sensing and four directions of obstacle avoidance. Compared to the Phantom 4 Advanced variant, the Pro features the noted four, rather than two, directions of obstacle avoidance and offers a 5.8 GHz channel for the Lightbridge link, in addition to 2.4 GHz.
Standard: The aircraft follows the route at a constant speed with the camera facing in the direction of flight.
Free: The aircraft only moves along the route when instructed. In this mode, the camera can face in any direction during a flight.
Trace: Follow behind or in front of a subject, avoiding obstacles automatically.
Profile: Fly alongside a subject at a variety of angles to get profile shots of the subject.
Spotlight: Keep the camera trained on a subject while the aircraft flies almost anywhere.
TapFly Forward: Tap to fly in the selected direction
TapFly Backward: Tap to fly in the opposite direction of the tap, i.e. tap in the bottom right corner of the screen to fly backward towards the top left.
TapFly Free: Lock the forward direction of the Phantom without locking the camera direction allowing it to turn as it flies.
Note: Obstacle Avoidance is not available with TapFly Free.
Based on its altitude at the time of disconnection, the Phantom 4 Pro is also able to adjust its flight path to avoid obstacles it has seen during its flight. At takeoff, the Phantom 4 Pro will record the scene below and compare its recording with what it sees as it returns, for more precise landing. It can also detect the ground to see whether there is suitable spot for landing. If any obstacles are found, or there is water on the ground, it will alert the pilot and hover at an appropriate height, helping the aircraft to land more safely.
