Audio
You can use not only video images on the XO device, but also audio – both in and out.
13.1
Audio IN
Audio input is available from the cameras' audio inputs, or from IP audio devices such as the Axis horn speaker.
The iFT Series does not support analogue audio in.
You can choose to record audio, and listen to audio in the live view. For an overview of IP cameras that support
audio in, see the
Supported IP Camera List
(26742). Usage of IP audio modules is similar to IP cameras with
audio in capabilities. For details, see
Note
l
If the connection bandwidth is low, it is recommended to disable live audio streaming.
l
Audio IN is unbalanced audio.
l
Changing the audio settings requires a system restart.
In the XO client, you have to enable the audio inputs for recording and listening in the live view. For more
information, see the
XO Client Software User Manual
(21796).
13.2
Audio OUT (Talkback)
13.2.1
Options
Talkback to the site works via the
Live Video
window in the XO client software. You select a camera, and then
use the microphone (typically connected to the client PC) to talk to the site via the speaker that is associated with
that camera.
If you need
only one speaker
on your site, you have the following options:
l
Connect an amplified loudspeaker to the audio out plug of the motherboard (= green 3.5 mm jack).
l
Connect an amplified loudspeaker to the audio output on the MIO card (with built-in MIO card only, not
available on an external XO I/O Interface USB module).
In this case, all cameras are automatically associated with that one speaker.
