* Range: DJI drones utilize radio frequency communication for control. Range varies with signal strength and interference, typically reaching 7-10km for most models. Some offer long-range capabilities (up to 15km) with specific transmission systems.
* Speed: DJI drones are known for their agility and speed. They can typically fly at around 40-50 km/h, with some models reaching higher speeds.
* Obstacle Avoidance: Most DJI drones feature sophisticated obstacle avoidance systems with multiple sensors (sonar, visual, and infrared) to detect and navigate around objects. Advanced models offer more robust 360�� obstacle avoidance.
2. Camera and Imaging:
* Camera Resolution: DJI offers drones with high-resolution cameras ranging from 4K (3840x2160 pixels) to 5.4K (5472x3078 pixels) for capturing stunning aerial footage.
* Sensor Size: Larger sensor sizes (e.g., 1-inch CMOS) result in better low-light performance and greater dynamic range for capturing richer details and colors.
* Gimbal Stabilization: 3-axis stabilized gimbals ensure smooth and stable video footage even during flight.
* Zoom Capabilities: Some models offer optical or hybrid zoom functionalities, allowing you to zoom in on subjects without losing image quality.
* Advanced Features: DJI drones offer features like HDR, D-Log profiles, and RAW image capturing for professional-level photography and videography.
3. Flight Modes and Intelligent Features:
* ActiveTrack: This feature allows the drone to automatically track moving subjects, like people or vehicles.
* Point of Interest (POI): Allows the drone to fly in circles around a specific point, capturing 360�� footage.
* Waypoints: Pre-programmed flight paths can be set for automated flights, enabling complex aerial photography or inspections.
* RTH (Return to Home): This feature automatically guides the drone back to the takeoff point if the signal is lost or the battery is low.
* Gesture Control: Some models enable control using simple hand gestures, offering an intuitive flying experience.
* Flight Planning: Advanced apps like DJI Pilot allow for detailed flight path planning, mission management, and data collection for professional applications.
4. Connectivity and Data Management:
* Remote Control: DJI drones are controlled with dedicated remote controllers, providing real-time control and monitoring. Some models offer compatibility with mobile devices.
* Data Storage: SD card slots allow for storing captured footage and photos.
* Cloud Storage: DJI's cloud service, DJI Fly, allows for file storage, editing, and sharing.
* Live View: Real-time video feed from the drone is displayed on the remote controller or mobile device, enabling live monitoring and adjustments.
5. Battery and Power:
* Flight Time: Battery life is crucial for drone operation. DJI offers various battery capacities, affecting flight time and performance.
