Audio Channel
- Full duplex: Select it for simultaneous communication in both direction between the
connected administrator and IP CAM. It means both parties can speak and be
heard at the same time.
- Half duplex: Select it for communication in both directions, but only one direction at a time. It
cannot receive signal until the transmission has been done. Therefore, once
one party speaks but can’t hear the voice, and vice versa.
- Talk only: It narrows down to one way just for talking.
- Listen only: It narrows down to one way just for listening.
Audio Input
Select the microphone input gain value you wish in the drop-down menu, and based on your
region to select the proper codec and save all settings.
- G.711 U-law: one codec for “Computer Audio”, used in North America & Japan areas.
- G.711 A-law: another codec for “Computer Audio”, used in Europe and the rest of the
world.
- AMR Audio: an audio codec of the third generation communication for mobile phone.
While the option selected, your mobile phone will receive the audio file from
IP Camera. And you can choose the bit rate from 4.75k to 12.2k. However,
the usage of this codec will cause frame-rate decreasing.
- Off: audio file won’t be transmitted by IP CAM.
Audio Output
Select the speaker output gain value you wish in the drop-down menu and save it.
Note: The Camera does not support echo cancelling; using the full duplex mode may cause
