Audio out
 Note
If an excessive audio level or gain value is set, a deterioration of sound quality or a howling
sound may occur.
Bitrate
The bitrate of the G.711 codec is 64 Kbps and cannot be changed. The bitrate of the
G.726 codec is 16, 24, 32 and 40 Kbps; the compression ratio can be changed. Only
48 Kbps can be selected for the AAC codec. (Supported [Codec] options may differ
depending on the camera specifications.)
Gain
Sets the amplification value of audio in. If the input sound is too low, you can increase
the gain value to amplify the input audio signal. The range of gain value is from 1 to 10;
a larger value means higher amplification.
Noise reduction
Select Noise Reduction if the surrounding noise is too strong to hear the sound of
interest.
Noise reduction may not work properly if noise is indistinguishable from the surrounding
voice sound, or if the sound pressure is high.
Sensitivity: You can set the noise reduction sensitivity based on the level of ambient
noise.
You can output audio through the built-in speaker.
Audio out
To use audio out, select [Enable].
Gain
Sets the amplification value of audio out. If the output sound is too low, you can
increase the gain value to amplify the output audio signal. The range of gain value is
from 1 to 10; a larger value means a louder audio out. Gain is activated only when
[Enable] is selected for audio out.
