PRIMARY STREAM AND SECONDARY STREAM
The Primary Stream and Secondary Stream are video streams that include compression, resolution, image rate, and bit rate settings. The streams
can be set up using a video preset setting, or they can be customized using the video configuration settings.
A video preset is a predefined video configuration that offers a good balance between video performance and bandwidth usage. For easy stream
configuration, use the Video Preset page located in the drop-down menu of the A/V Streams Tab.
To customize the Primary Stream or Secondary Stream use the Video Configuration page located in the drop-down menu of the A/V Streams Tab.
Configurable settings include the stream name, compression standard, resolution setting, image rate, and bit rate. The default names for the
streams are Primary Stream and Secondary Stream; however, if these stream names have been changed, the new names will replace the default
names (Primary Stream and Secondary Stream) on the Select Stream page.
QUICKVIEW STREAM
The QuickView Stream is a predefined JPEG video stream with VGA resolution. This low resolution, low frame rate stream is displayed when the
Imaging Tab settings are configured. This allows users to view changes to exposure, white balance, and tone map settings as they are configured
and before the settings are saved.
The QuickView Stream is also ideal for users who are connected to a network with processor bandwidth limitations that might cause a high
resolution, high frame rate video stream to pause or appear pixilated.
The aspect ratio of the QuickView Stream mirrors that of the Primary Stream. The only stream setting that is selectable is the framerate: 2 ips
or 1 ips.
