24AXIS 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.

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-duplexmode 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. 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-duplexmode instead.
