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 AAC or GSM-AMR and the bit rate

Advanced Mode

■ 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.

■ GSM-ARM is designed to optimize speech quality and requires less bandwidth. The bit rates are

selectable from: 4.75Kbps, 5.15Kbps, 5.90Kbps, 6.7Kbps, 7.4Kbps, 7.95Kbps, 10.2Kbps, and

12.2Kbps.

■ G.711 also provides good sound quality and requires about 64Kbps. Select pcmu (μ-Law) or pcma

(A-Law) mode.

When completed with the settings on this page, click Save to enable the settings.

Advanced Mode

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.
