What type of obstacle sensing sensors does the DJI Mavic 4 Pro have, and how do they work: The DJI Mavic 4 Pro integrates a highly advanced obstacle sensing system, comprised of omnidirectional sensors, front-facing LiDAR, and a three-dimensional infrared system. These components work together to identify and avoid obstacles in all directions, both during automatic and manual flight. Thanks to the front-facing LiDAR, the drone can accurately calculate the distance to objects at high speed, significantly improving responsiveness even in low-light environments.

This sensor system not only helps avoid collisions but also improves hovering accuracy in tight or complex spaces, especially when the GNSS signal is weak or nonexistent. The Downward Vision System is supported by an auxiliary light that automatically activates when the drone is less than five meters above the ground, facilitating a safe landing. Active Vision technology also adjusts in real time to ensure the Mavic 4 Pro can dynamically adapt to its environment.

One of the key features is the Advanced Pilot Assistance System (APAS), which allows the drone to automatically avoid obstacles while maintaining the desired flight path. This feature is essential for flights in urban, forest, or mountainous environments, where obstacle density can be high. The operator can select between different avoidance modes—such as Bypass or Brake—from the DJI Fly app, providing an additional level of flight customization depending on the mission.

It's important to note that, although the Mavic 4 Pro's obstacle sensing system is highly advanced, DJI emphasizes that it does not replace the pilot's responsibility. In extreme conditions such as rain, dense fog, or flights over water, the sensors may not function optimally. Therefore, it is essential that the user maintain visual contact with the drone and be prepared to intervene manually if necessary, always ensuring the safety of the operation.
