ActiveTrack is a feature found in many drones, particularly those made by DJI. It allows the drone to automatically follow and capture video of a moving subject, such as a person or vehicle, without requiring manual control. This technology uses advanced sensors and computer vision to identify and track the subject in real-time. With ActiveTrack, users can focus on their activities while the drone handles the filming. The feature offers different tracking modes, enabling the drone to adapt to various scenarios, whether the subject is walking, running, or cycling. This makes it a popular choice for outdoor enthusiasts and content creators.
