NOTE:
► Video quality and fixed quality refers to the compression rate, so a lower value will produce higher
quality.
► Converting high-quality video may significantly increase the CPU loading, and you may encounter
streaming disconnection or video loss while capturing a complicated scene. In the event of occurence,
we suggest you customize a lower video resolution or reduce the frame rate to obtain smooth video.

Audio Settings
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 AAC, G.711, or G.726, and the sampling bit rate .
■ AAC provides good sound quality at the cost of higher bandwidth consumption. The bit rates are
selectable from: 16Kbps, 32Kbps, 48Kbps, 64Kbps, 96Kbps, and 128Kbps.
■ 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.
IMPORTANT:
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 uncheck the Mute option.
