Status
If you audio is important to what you are monitoring, you need to set the audio status to Enable. So that the microphone can
pick up sounds in the environment. On the other hand, if audio is not necessary (for instance an open space with a lot of noises),
you are advised to disable the audio to reduce the clips file size. The default sample rate is 8k, and the bit rate is 16 bit.
Input Gain: setting the sensitivity of the microphone. High gain will result in higher volume and but picks up more noise.
Encoding: supports G711A, AAC and G711U.
