AXIS 241QA/AXIS 241SA - Audio 23

Audio

The AXIS 241QA/AXIS 241SA can transmit audio to other clients using an external microphone and can play audio received from other clients by attaching a speaker. The Audio Settings allow different audio configurations to be set up, such as full duplex, half duplex, and simplex.

Note: The speaker attached to the audio output of the AXIS 241QA/AXIS 241SA must have a built-in amplifier, which is the case for e.g. some PC speakers.

Audio Settings

This section describes how to configure the basic audio settings for the AXIS 241QA/AXIS 241SA, 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 241QA/AXIS 241SA will transmit and receive audio from.

Audio Channels

There are two mono audio channels between the AXIS 241QA/AXIS 241SA and a 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.
