Enhanced Transmission and Controllers
One of the standout upgrades is the adoption of the o4 transmission system, DJI’s flagship technology, offering superior connectivity and control. The Mini 4 Pro works seamlessly with the new RC2 and RCN2 remote controllers, providing users with flexibility in choosing their preferred controller setup. The integration of an auxiliary LED under the drone enhances visibility during low-light conditions, a feature unexpected in a mini-class drone.

Omnidirectional Obstacle Avoidance
Perhaps the most significant leap in technology for the Mini 4 Pro is the inclusion of omnidirectional obstacle avoidance. This means the drone now boasts sensors facing forward, backward, and downward, ensuring comprehensive detection and protection against obstacles. The upgraded camera sensors, with a wider field of view, further improve obstacle detection, setting a new standard for safety in mini drones.

Camera Hardware and Features
While the camera hardware remains similar to that of the Mini 3 Pro, the software has seen significant improvements. Users can now enjoy a higher dynamic range when shooting videos, more frame rate options, and additional shooting modes. The Mini 4 Pro retains its ability to shoot 4K video and capture high-quality 48-megapixel still images. Notably, new color profiles, such as hlg and d-log, enable 10-bit color depth, offering improved post-processing capabilities.

Impressive Flight Modes
The Mini 4 Pro comes equipped with a comprehensive suite of intelligent flight modes, including FocusTrack features like Active Track, Point of Interest, and Spotlight. However, the star of the show is the enhanced Active Track. It now features Touch Trace, allowing users to define the drone’s path with ease. The system’s ability to recognize and adapt to different tracking subjects, whether it’s a car, boat, or human, adds to its versatility. While it excels in many scenarios, there is room for improvement in making it more user-friendly during activities where manual control is challenging.

Waypoints and Cruise Control
The introduction of Waypoints and Cruise Control to the Mini series brings advanced flight planning capabilities. Waypoints allow users to create complex missions with customized actions, including capturing photos and videos at specific points. Cruise Control simplifies flying by maintaining the drone’s movement in the desired direction without continuous stick inputs, making it an excellent choice for point-to-point flight scenarios.
