AXIS 243SA - Audio
Audio
The AXIS 243SA 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, half duplex and simplex.
Note:
The speaker attached to the audio output must have a built-in amplifier, as is the case with, for example,
some PC speakers.
Audio settings
This section describes how to configure the basic audio settings, such as, setting the
communication mode and adjusting the sound levels in the microphone and speaker
connected to the camera.
Enable Audio
Select the video sources that the AXIS 243SA
will transmit and receive audio from.
Audio Channels
There are two mono audio channels for the AXIS 243SA and each
connected client, one
for receiving audio and the other for transmitting audio. Each audio channel can be turned
on or off, which means there are four audio mode options that can be used.
Full-duplex mode means that you ca
n 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. The only controls you may wish to use are the mute buttons to turn off the
sound, and the sliders, to adjust the input/output volume levels. This mode requires that
the client PC has a sound card with support for full-duplex audio. If your available
bandwidth is 0.2 Mbit/s or less, it is recommended that you use Half-duplex mode instead.
