User guide

- 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 external line source can be connected to the terminal I/O of the network camera.

- Input:

Select either Internal or External Amp from the drop down menu.

- 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 option is available;

check the box for no sound to the device. From the dropdown menu, select the volume (dB).

• 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.

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

Uncheck the Enable full duplex box to enable Simplex mode. The simplex mode only

transmits audio from the network camera to any web client. It does not receive audio from

other web clients.

- 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.

Mute:

Check the box to enable the mute mode; you will not be able to transmit audio signal.

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