4) Audio
The network camera can transmit audio to other clients using an external microphone and can
play audio received from other clients by attaching a speaker. The Setup page has an
additional menu item called Audio, which allows different audio configurations, such as full
duplex and simplex.
Audio Setting:
- Enable audio:
Check the box to enable audio in the video stream.
- Compression type:
Select the desired audio Compression format, G.711.
- 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 bit rate:
Depending on the selected encoding, set the desired audio quality
(bit rate). The settings affect the available bandwidth and the required audio quality.
Audio Input:
Audio from an external line source can be connected to the STEREO Jack I/O
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.
Audio Output:
- Enable full duplex:
Check the box to enable Full Duplex mode. This means that you can
transmit and receive audio (talk and listen) 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 box 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.
When satisfied with the settings, click the
Save
button, or click the
Reset
button to revert to
previously saved settings.
