Chapter 10 Video and Audio
This part introduces configuring video and audio related parameters.
10.1 Video Settings
This section introduces setting video parameters such as stream type, video encoding, and resolution.
Go to setting page: Configuration Video/Audio Video.
For a device with multiple camera channels, select a channel before other settings.
10.1.1 Stream Type
For a device that supports more than one stream, you can specify parameters for each stream type.
Main Stream
Main stream stands for the best stream performance the device supports. It usually offers the best
resolution and frame rate the device can attain, but high resolution and frame rate usually mean larger
storage space and higher bandwidth requirements in transmission.
Sub Stream
Sub stream usually offers comparatively low resolution options, which consume less bandwidth and
storage space.
Other Streams
Steams other than the main stream and sub stream may also be offered for customized usage.
10.1.2 Video Type
Select the content (video and audio) that should be contained in the stream.
Video: Only video content is contained in the stream.
Video & Audio: Video content and audio content are contained in the composite stream.
10.1.3 Resolution
Select video resolution according to actual needs. Higher resolution requires higher bandwidth and
storage.
10.1.4 Bitrate Type and Max. Bitrate
Constant Bitrate: The stream is compressed and transmitted at a comparatively fixed bitrate. The
compression speed is fast, but mosaic may occur on the image.
Variable Bitrate: The device automatically adjusts the bitrate under the set Max. Bitrate. The
compression speed is slower than that of a constant bitrate, but it guarantees the image quality of
complex scenes.
