Phantom 4 Pro Drones – Dynnex Drones

Gimbal Camera with 1" CMOS Sensor

The onboard camera features a first for the Phantom line: a 1-inch 20-megapixel CMOS sensor. A custom-engineered lens made up of eight elements is arranged in seven groups. The camera boasts a mechanical aperture that eliminates rolling shutter distortion that can occur when taking images of fast moving subjects or when flying at high speed and a mechanical focus.

1" CMOS Sensor

Sensor size is often more important to image quality than the number of pixels, because a larger sensor has dynamic range, better signal-to-noise ratio, and boosted low light performance. The 1" 20MP CMOS sensor in the Phantom 4 Pro is almost four times the size of the Phantom 4's 1/2.3" sensor. It uses larger pixels and has a maximum ISO of up to 12,800 as well as increased contrast.

H.264 and H.265 4K Video Recording

Powerful video processing supports H.264 4K videos at 60 fps or H.265 4K at 30 fps, both recorded in a 100 Mbps bitrate. Advanced sensors and processors ensure everything is captured with more image detail and the image data needed for manipulation in post-production.

Production-Optimized 4K

An enhanced video processing system allows video to be captured in cinema- and production- optimized DCI 4K (4096 x 2160) at 60 fps and a bitrate of 100 Mbps. The Phantom 4 Pro also supports the H.265 video codec at 30 fps in 4K resolution. For a given bitrate, H.265 doubles the amount of image processing as H.264, resulting in significantly enhanced image quality from a more efficient compression. Record in the high dynamic range D-log mode to make the most of this image data for color grading.

High Resolution Lens

The Phantom 4 Pro camera has an aerial-optimized f/2.8 wide-angle lens with a 24 mm equivalent focal length. It features eight elements — two aspherical — arranged in seven groups that fit into a smaller, more compact frame. Its images are consistently detailed with low distortion and low dispersion, ensuring that photos and videos are sharp and vivid.

Mechanical Shutter

Capturing objects moving at high speed has always been a challenge for flying cameras using an electronic shutter. This is why the Phantom 4 Pro is the first DJI Phantom to use a mechanical shutter and a large-aperture prime lens. A maximum mechanical shutter speed of 1/2000-second eliminates motion blur and "jello effect" caused by shooting a fast moving object with a rolling electronic shutter. The electronic shutter has also been improved with a max shutter speed of 1/8000-second, and a there is Burst Mode shoot capable of shooting 14 fps at 20 megapixels to catch the perfect moment.

Remote Controller with Lightbridge HD Video Link

The Phantom 4 Remote Controller Included controller integrates an upgraded Lightbridge HD video transmission system that adds 5.8 GHz transmission support. The ability to choose between 2.4 GHz and 5.8 GHz allows pilots to cut through interference and eliminates image lag caused when flying in an area with extensive 2.4 GHz frequency use. Normally, Wi-Fi video transmission systems use a 2.4 GHz frequency to work with a controller using a 5.8 GHz frequency, as this prevents interference that can occur when both use the same frequency.

Lightbridge HD Video Link

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 2.4 GHz frequency band is often affected by Wi-Fi, 4G cell towers, and other types of interference in urban areas, a 5.8 GHz band will increase transmission reliability. When switched on, the Phantom 4 evaluates local signal levels, automatically choosing the transmission frequency with the lowest level of interference. This enables a maximum video transmission range of 4.3 miles.

Flight Control System

Flight Modes

Different productions require different flight characteristics, and the Phantom 4 Pro offers three modes for flight: P, A and S. Switching between them allows pilots to get the control they need, whether they seek smoothness, simplicity, intelligent navigation, or speed. In Position Mode (P), TapFly, ActiveTrack, obstacle sensing and positioning features are available. Sport Mode (S) adds extra agility and higher speed, reaching 45 mph . Attitude Mode (A) switches off satellite stabilization and holds the Phantom 4 Pro's altitude. It is ideal for experienced pilots looking to capture smoother footage. Tripod Mode, which limits speed to 4 mph provides precision control for fine framing and indoor flying. Both the infrared sensing system and vision sensors are enabled in these modes for a safer flight experience.

Sensor Redundancy

The Phantom 4 Pro features dual compass modules and dual IMU units, making it more reliable when compared to many hexacopters and octocopers. Compasses and IMUs are important sensors to ensure a stable flight and the Phantom 4 Pro constantly compares the data it receives through both pairs. This data is run through various algorithms to check accuracy, and any inaccurate data is simply discarded without affecting flight, keeping flight steady and reliable.

Intelligent Battery System

Professional aerial imaging benefits from longer flight times. The Phantom 4 Pro features a maximum flight time of 30 minutes, providing more time in the air to capture the perfect shot. The DJI GO app shows battery lifetime and calculates remaining flight times according to distance traveled and more. It will give alerts when it reaches a minimum safe amount required for a safe journey back to the takeoff point. An advanced battery management system is also in place to prevent overcharging and over draining. When placed in longer term storage, batteries will discharge power to maintain good health.
