2. Select the Stream Type of the speed dome to main stream (normal), sub-stream or third
stream. The main stream is usually for recording and live viewing with good bandwidth, and
the sub-stream can be used for live viewing when the bandwidth is limited. Refer to the
Section 4.1 Configuring Local Parameters for switching the main stream and sub-stream for
live viewing.
3. You can customize the following parameters for the selected stream.
The parameters vary depending on the models of the speed dome.
Video Type:
Select the stream type to video stream, or video & audio composite stream. The audio signal
will be recorded only when the Video Type is Video & Audio.
Resolution:
Select the resolution of the video output.
Bitrate Type:
Select the bitrate type to constant or variable.
Video Quality:
When bitrate type is selected as Variable, 6 levels of video quality are selectable.
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.
Max. Bitrate:
Set the max. bitrate. The higher value corresponds to the higher video quality, but the higher
bandwidth is required.
Video Encoding:
Select Video Encoding from the dropdown list for different stream type.
H.265+/H.264+:
Set it as ON or OFF.
Profile:
Basic Profile, Main Profile and High Profile are selectable.
I Frame Interval:
Set the I-Frame interval from 1 to 400.
SVC:
Scalable Video Coding is an extension of the H.264/AVC standard. Select OFF/ON to
disable/enable the SVC function. Select Auto, and the device will automatically extract frames
from the original video when the network bandwidth is insufficient.
Smoothing:
It refers to the smoothness of the stream. The higher value of the smoothing, the better
fluency of the stream, though, the video quality may not be so satisfied. The lower value of
the smoothing, the higher quality of the stream, though it may appear not fluent.
