An uprated camera is equipped with a 1-inch 20-megapixel sensor capable of shooting 4K/60fps video and Burst Mode stills at 14 fps.The adoption of titanium alloy and magnesium alloy construction increases the rigidity of the airframe and reduces weight, making thePhantom 4 Pro similar in weight to the Phantom 4. The FlightAutonomy system adds dual rear vision sensors and infraredsensing systems for a total of 5-direction of obstacle sensing and 4-direction of obstacle avoidance.
CAMERA WITH 1-INCH 20MP SENSOR
The onboard camera has been redesigned to use a 1-inch 20-megapixel CMOS sensor. A custom engineered lens made up of eight elements isarranged in seven groups, it is the first DJI camera to use a mechanical shutter, eliminating rolling shutter distortion which can occur when takingimages of fast moving subjects or when flying at high speed. In effect, it is as powerful as many traditional ground cameras. More powerfulvideo processing supports H.264 4K videos at 60fps or H.265 4K at 30fps, both with a 100Mbps bitrate. Advanced sensors and processorsensure everything is captured with more image detail and the image data needed for advanced post-production.
5-DIRECTION OF OBSTACLE SENSING
FlightAutonomy is expanded with an additional set of high-resolution stereo vision sensors placed at the rear in addition to the pair placed at the frontas well as infrared sensing systems placed on the left and right sides. This network creates a total of 5-direction of obstacle sensing and 4-direction ofobstacle avoidance, protecting the Phantom 4 Pro from more obstacles and giving filmmakers the confidence to capture more complex images.
6-CAMERA NAVIGATION SYSTEM
Three sets of dual vision sensors form a 6-camera navigation system that works constantly to calculate the relative speed and distance between theaircraft and an object. Using this network of forward, rearward and downward vision sensors, the Phantom 4 Pro is able to hover precisely in placeswithout GPS when taking off indoors, or on balconies, or even when flying through windows with minimal pilot control. In the unlikely event that frontand downward sensors are unable to operate, the aircraft can still hover in place using the rear stereo vision system. The Phantom 4 Pro also is ableto fly in complex environments at a flight speed of up to 31mph (50kph) while avoiding obstacles in its path. In Narrow Sensing Mode, the Phantom 4Pro narrows its sensing scope enabling it to see in more detail and fly through small spaces.
NEW LIGHTBRIDGE VIDEO TRANSMISSION SYSTEM
The Phantom 4 Pro controller integrates an upgraded Lightbridge HD video transmission system that adds 5.8 GHz transmission support. The ability to choose between2.4GHz and 5.8GHz allows pilots to cut through interference and eliminates image lag caused when flying in an area with extensive 2.4GHz frequency use. Normally, Wi-Fi video transmission systems use a 2.4GHz frequency to work with a controller using a 5.8GHz frequency as this prevents interference that can occur when both use thesame frequency. If using the same frequency the video transmission system and the remote controller will interfere with each other, causing image lag.
The Lightbridge HD video transmission system used in the Phantom 4 Pro uses TDM (Time Division Multiplexing) to transmit signals, allowing it to send controller signalsand receive video transmission signals at the same frequency. When switched on, the Phantom 4 Pro evaluates local signal levels, automatically choosing thetransmission frequency with the lowest level of interference. This ensures the optimum range of a maximum video transmission of 4.3mi (7km)*.
