• Audio Setting

- Enable audio:

Check the box to enable audio in the video stream.

- Compression type:

Select the desired audio compression format, G711. The "u-law is for North America and

Japan; the "a-law" is for Europe and the rest of the world.

- Sample rate:

Select the required Sample rate (number of times per second the sound is sampled). The

higher the sample rate, the better the audio quality and the greater the bandwidth required.

- Sound bitrate:

Depending on the selected encoding, set the desired audio quality (bitrate). The settings

affect the available bandwidth and the required audio quality.

• Audio Input

Audio from an internal or external line source can be connected to the I/O terminal of the

network camera.

- Input volume:

If there are problems with the sound input being too low or high, it is possible to adjust the

input gain for the microphone attached to the network camera. A Mute button is provided;

check the box to hear no sound on the device.

• Audio Output

- Enable full duplex:

Check the box to enable Full Duplex mode. This means that audio (talk and listen) can be

transmitted and received at the same time, without having to use any of the controls. This is

just like having a telephone conversation. A Mute button is provided; check the box to hear

no sound from the speakers.

This mode requires that the client PC has a sound card with support for full-duplex audio.

- Output volume:

If the sound from the speaker is too low or high it is possible to adjust the output gain for

the active speaker attached to the network camera.

When the settings are complete, click Save, or click Reset to revert to previously saved settings.
