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:

•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.

•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 2-25, 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.

Table 3-10describes the options in the Audio window.
