Chapter 3 Configuring and Managing the IP Camera
Audio/Video Windows
Audio Window
The Audio window provides options for enabling and configuring audio that is transmitted to and from
the IP camera. You can configure audio for these devices:
• Internal microphone—The IP camera includes an internal microphone that can capture audio at the
camera location. This audio is sent to the PC that you use to view video from the IP camera. You
can listen to the audio when viewing video in the Home window.
• External microphone—You can connect an optional external microphone (available from
third-parties) to the IP camera. This audio is sent to the PC that you use to view video from the IP
camera. You can listen to the audio when viewing video in the Home window. Connecting an
external microphone disables the internal microphone.
• External speaker— You can connect an optional external speaker (available from third-parties) to
the IP camera. This speaker plays audio that is captured by the microphone of the PC that you use
to view video from the IP camera. The PC can capture and send this audio only when the Home
window is open.
To display the Audio window, access the configuration windows as described in the “Accessing the IP
Camera Windows” section on page 2-6, click Audio/Video, then click Audio.
If you change any options in the Audio window, you must click Save to save the changes. To discard the
changes, click Cancel before clicking Save. These buttons appear at the bottom of the window. You may
need to scroll down to see them.
