26 AXIS 214 PTZ - Audio
Audio
The AXIS 214 PTZ can transmit audio to other clients, by connecting a microphone and
can play audio received from other clients by attaching a speaker.
Note: The speaker attached to the Line out connector on the AXIS 214 PTZ must have a
built-in amplifier, which is available in e.g. some brands of PC speakers.
This section describes how to configure the basic audio settings for the AXIS 214 PTZ, e.g.
set the communication mode and adjust the sound levels for the microphone and speaker.
Enable Audio
Enables audio transmission to and from the AXIS 214 PTZ. Refer to Connecting audio
equipment, on page 50 for more information.
Audio Channels
There are two mono audio channels between the AXIS 214 PTZ and other clients, one for
receiving audio and one for transmitting audio. Each audio channel can be turned on or
off, which means that there are four audio mode options that can be used.
• Full-duplex audio is when you can transmit and receive audio (talk and listen) at
the same time, as when having a telephone conversation. The only controls you
may wish to use are the mute buttons to turn off the sound, and the level sliders
for adjusting the input/output volume. This mode requires the client PC to have 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.
