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 the Phantom 4 Pro similar in weight to the Phantom 4. The FlightAutonomy system adds dual rear vision sensors and infrared sensing systems for a total of 5-direction of obstacle sensing and 4-direction of obstacle avoidance.
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 front as 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 of obstacle avoidance, protecting the Phantom 4 Pro from more obstacles and giving filmmakers the confidence to capture more complex images.
The onboard camera has been redesigned to use a 1-inch 20-megapixel CMOS sensor. A custom engineered lens made up of eight elements is arranged in seven groups, it is the first DJI camera to use a mechanical shutter, eliminating rolling shutter distortion which can occur when taking images of fast moving subjects or when flying at high speed. In effect, it is as powerful as many traditional ground cameras. More powerful video processing supports H.264 4K videos at 60fps or H.265 4K at 30fps, both with a 100Mbps bitrate. Advanced sensors and processors ensure everything is captured with more image detail and the image data needed for advanced post-production.
The Phantom 4 Pro controller integrates an upgraded Lightbridge HD video transmission system that adds 5.8 GHz transmission support. The ability to choose between 2.4GHz 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 the same frequency.
If using the same frequency the video transmission system and the remote controller will interfere with each other, causing image lag. The use of two different frequencies has drawbacks in terms of flight performance. For example, flight performance will be affected when either of the two frequencies suffer interference. 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 signals and receive video transmission signals at the same frequency. As the 2.4GHz frequency band is often affected by Wi-Fi, 4G cell towers, and other types of interference in urban areas, a 5.8GHz band will increase transmission reliability. When switched on, the Phantom 4 Pro evaluates local signal levels, automatically choosing the transmission frequency with the lowest level of interference.
This ensures the optimum range of a maximum video transmission of 4.3mi (7km)* A 5.5in 1080p screen integrated with the Phantom 4 Pro + offers 1000 cd/m2 of brightness, more than twice as bright as conventional smart devices. It makes bright, vivid colors easily visible in direct sunlight. With this screen, a mobile device is not required, simplifying pre-flight preparations. As the DJI GO 4 app is built into the screen, hardware and software can be fully optimized, further reducing video lag. Integration of an HDMI port, Micro SD card slot, microphone, embedded loudspeaker, and Wi-Fi connection allow images to be edited inside DJI GO 4 to be shared almost instantly.
Lastly, a five-hour battery life makes the Phantom 4 Pro + a complete aerial imaging solution.
