Only video content is contained in
the stream.
Video & Audio
Video content and audio content are contained in the composite
stream.
11.1.3 Resolution
Select video resolution according to actual needs. Higher resolution requires higher
bandwidth and storage.
11.1.4 Bitrate Type and Max. Bitrate
Constant Bitrate
It means that 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
It means that the device automatically adjust the bitrate under the set
Max. Bitrate
.
The compression speed is slower than that of the constant bitrate. But it guarantees
the image quality of complex scenes.
11.1.5 Video Quality
When
Bitrate Type
is set as Variable, video quality is configurable. Select a video quality
according to actual needs. Note that higher video quality requires higher bandwidth.
11.1.6 Frame Rate
The frame rate is to describe the frequency at which the video stream is updated and
it is measured by frames per second (fps).
A higher frame rate is advantageous when there is movement in the video stream, as it
maintains image quality throughout. Note that higher frame rate requires higher bandwidth
and larger storage space.
