Chapter 9 Video and Audio
This section introduces configuring video and audio parameters.
Video Settings
This introduces setting video parameters such as stream type, video encoding, and resolution.
Go to setting page: Configuration → Video/Audio → Video.
Stream Type
For devices that support more than one stream, you can specify parameters for each stream type.
Main Stream: 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 means larger storage
space and higher bandwidth requirements in transmission.
Sub Stream: Comparatively low resolution option, which consumes less bandwidth and storage space.
•
•
Other Streams: Steams other than the main stream and sub stream may also be offered for customized
usage.
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.
Resolution
Select video resolution according to actual needs. Higher resolution requires higher bandwidth and
storage.
Bitrate Type and Max.Bitrate
• Constant Bitrate: Stream is compressed and transmitted at a comparatively fixed bitrate. The
compression speed is fast, but mosaic may occur on the image.
• Variable Bitrate: Device automatically adjusts the bitrate under the set Max.Bitrate. The compression
speed is slower than constant bitrate, but it guarantees the image quality of complex scenes.
Video Quality
When Bitrate Type is set as Variable, video quality is configurable. Select video quality according to actual
needs. Note that higher video quality requires higher bandwidth.
