The Audio/Video windows provide options for configuring audio and video from the IP camera.
The following sections describe the Setup windows in detail:

Video Window
The Video window provides options for configuring the video from the IP camera. You can configure
settings for the primary and an optional secondary video stream.
Configuring a secondary stream is useful for providing a video stream that is at a lower resolution than
the primary stream to third-party devices or software. Some devices and software require this lower
resolution. For related information, see the
“Viewing Video through Third-Party Devices or Software”
To display the Video window, access the configuration windows as described in the
Initial Setup of the IP Camera” section on page 2-4

Resolution
Select the desired video resolution format for the primary video stream from
the IP camera.
The default resolution is 720 x 480 for NTSC or 720 x 576 for PAL.
Video Quality Control
Choose an option for the video quality of the primary video stream from the
IP camera:
•
Constant Bit Rate—Specifies that the video stream is output at or close
to the constant bit rate that you choose. The default value is 4 Mbps. A
higher bit rate provides better video quality but consumes more
bandwidth.
•
Fixed Quality—Specifies that video is output at a fixed quality, which
ranges from Very High to Very Low. The bit rate may vary to maintain
this quality. The default fixed quality is Normal. A higher fixed quality
provides better video quality but consumes more bandwidth.
You can use these options to help manage bandwidth use in your network.
For example, if the IP camera is focused on an area with little movement,
such as an emergency exit, you can configure it with a low fixed quality.
