DJI Phantom 4 Advanced Quadcopter Without Remote Controller and Battery Charger

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 Advanced 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.

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

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 bit rate of 100 Mb/s. The Phantom 4 Advanced also supports the H.265 video codec at 30 fps in 4K resolution. For a given bit rate, 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.

The Phantom 4 Advanced camera has an aerial-optimized f/2.8 wide-angle lens with a 24mm-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.

Capturing objects moving at high speed has always been a challenge for flying cameras using an electronic shutter. This is why the Phantom 4 Advanced uses 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 boasts a max speed of 1/8000-second, and a there is a Burst Mode capable of shooting 14 fps at 20 megapixels to catch the perfect moment.

Following fast-moving objects can be very challenging, but Advanced, image-recognition algorithms used by the Phantom 4 Advanced allow it to recognize and track an object while keeping it in frame. This algorithm also recognizes a range of subjects, from people to vehicles to animals, and will adjust its flight dynamics to match, ensuring smoother shots. Pilots can now choose between:

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.

Fly in any direction visible on-screen with a simple tap. Tap anywhere on-screen to smoothly adjust the direction of flight while automatically avoiding obstacles and tap the screen again or use control sticks to change direction. An AR route function shows the aircraft's real-time flight direction for reference as its route is adjusted. As it can be difficult to control altitude, course, speed and camera pitch simultaneously using joysticks, TapFly Free allows a pilot to set the direction of flight, allowing them to turn the Phantom 4 Advanced or tilt the gimbal as required without changing the direction of flight. There are two TapFly modes:

TapFly Forward: Tap to fly in the selected direction
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.

In its Return to Home mode, the Phantom 4 Advanced can automatically choose the best route to return home depending on environmental conditions. It records its route as it flies, allowing it to return along the same route avoiding obstacles if the control signal is disconnected.

Based on its altitude at the time of disconnection, the Phantom 4 Advanced is also able to adjust its flight path to avoid obstacles it has seen during its flight. At takeoff, the drone 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.

With Gesture Mode, selfies can be captured using a few gestures without the remote controller. Computer vision technology allows the Phantom 4 Advanced to take instructions through gestures. The subject simply lifts their arms when facing the camera and the aircraft will recognize this movement by locking on and placing the subject in the center of the frame. When ready for a photo, the subject holds their arms out to signal the aircraft. A three-second countdown will begin, making time to strike a pose, allowing moments to be captured without the remote control.

The Phantom 4 Advanced 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 Advanced 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.

Professional aerial imaging benefits from longer flight times. The Phantom 4 Advanced 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.
