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. Higher value corresponds to higher video quality, while the higher
bandwidth is required.
Video Encoding:
Select Video Encoding from the dropdown list for different stream type.
H.264+/H.265+:
Set it as ON or OFF.
H.264+: If you set the main stream as the stream type, and H.264 as the video encoding,
you can see H.264+ available. H.264+ is an improved compression coding technology
based on H.264. By enabling H.264+, users can estimate the HDD consumption by its
maximum average bitrate. Compared to H.264, H.264+ reduces storage by up to 50%
with the same maximum bitrate in most scenes.
H.265+: If you set the main stream as the stream type, and H.265 as the video encoding,
you can see H.265+ available. H.265+ is an improved compression coding technology
based on H.265. By enabling H.265+, users can estimate the HDD consumption by its
maximum average bitrate. Compared to H.265, H.265+ reduces storage by up to 50%
with the same maximum bitrate in most scenes.
Notes:
H.265+/H.265 function varies depending on different speed dome models.
You need to reboot the camera if you want to turn on or turn off the H.264+/H.265+.
If you switch from H.264+ to H.265+ directly, and vice versa, a reboot is not required
by the system.
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.
