The Phantom 4 Pro
The Phantom 4 Pro has an upgraded camera. It features 1-inch, 20-megapixel sensor capable of shooting 4K/60fps video with burst mode stills at 14 fps.
Use of titanium alloy and magnesium alloy increases airframe rigidity while reducing weight. The FlightAutonomy system adds dual rear vision sensors plus infrared sensing for a total of 5-directions of obstacle sensing and 4-directions of obstacle avoidance.
The onboard camera has been redesigned. A custom engineered lens has eight elements arranged in seven groups. This is the first DJI camera to use a mechanical shutter. This eliminates rolling shutter distortion – this can occur when taking images of fast moving objects or when flying at high speed. In addition, more powerful video processing supports H.264 4K videos at 60fps or H.265 4K at 30fps – both with a 100Mbps bitrate.
FlightAutonomy is an expanded feature. It has an additional set of high-resolution stereo-vision sensors in the rear. This in addition to a sensor pair in the front along with an infrared sensing systems on port and starboard sides. This sensing array creates a 5-direction of obstacle sensing system and a 4-direction obstacle avoidance system.
Many other new features sets the Phantom 4 apart from other quadcopters and drones.
