Mute : Select this option to disable audio transmission from the Network Camera to all clients. Note that
if muted, no audio data will be transmitted even if audio transmission is enabled on the Client Settings
page. In that case, the following message is displayed:
External microphone input gain : Select the gain of the external audio input according to ambient
conditions. Adjust the gain from +21 db (most sensitive) or -33db (least sensitive).
Audio type : Select audio codec as G.711 or G.726, and the sampling bit rate .
■ AAC support is fully adopted in contemporary listening devices, for talk, 32 (AAC)/64 (MP3) kbps is a
good standard setting for most purposes.
■ G.711 also provides good sound quality and requires about 64Kbps. Select pcmu (μ-Law) or pcma
(A-Law) mode.
■ G.726 is a speech codec standard covering voice transmission at rates of 16, 24, 32, and 40kbit/s.
When completed with the settings on this page, click Save to enable the settings.
The network camera does not come with embedded microphone. An external microphone will be
necessary especially if you prefer the Audio Detection feature. By default, the Audio setting is muted,
and you need to manually deselect the Mute option.
