The audio feature requires a certain amount of system resources be available on the camera, the video quality settings may need to be adjusted to free up the needed resources.
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
Note** when audio is enabled the camera sacrifices over all video quality settings.
- A video preset is a predefined video configuration that offers a good balance between video performance and bandwidth usage. For easy stream 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 on the Select Stream page.
