Action cameras typically come with built-in microphones that record audio. However, due to the camera’s small size and the fact that they are often used in noisy or windy environments, the audio quality may not always be optimal. Some action cameras offer external microphone support, which can help improve the quality of the audio recording. It’s important to note that using an external microphone may require additional equipment and setup, and may not always be practical in certain environments. Overall, while action cameras are primarily designed for video recording, the audio quality can still be sufficient for basic use.
