Altitude Hold allows a drone to maintain a consistent altitude by analyzing the pressure data further provided by a drone’s barometric pressure sensor. If a drone has an ultrasonic sensor, this is also used with Altitude Hold. This feature ensures even a small drone with camera will be able to hold itself in place while you snap some shots or record a video.
Many manufacturers mount cameras inside the body of the drone. This is acceptable for casual photography, but if you want more professional results, consider adding an external camera mount, or gimbal. Gimbals allow you to place your video or still camera in front of the drone body, away from the vibrating motor and rotors. Gimbals can swivel and pivot, providing you with additional control over your imagery.
