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.
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.
