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 pre-defined video configuration that offers a good balance between video
performance and bandwidth usage. For easy stream configuration, see the
Configuration" section on page
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. See the
section on page
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.
Unicast
A unicast transmission sends a separate video stream to each user that is requesting data. Although
multiple users might request the same data from the camera at the same time, duplicate video streams
are transmitted to each user. Every unicast user that connects to the camera consumes additional
processing power, which limits the number of simultaneous users who can access the camera.
The camera supports a maximum of 20 simultaneous users.
