Parameter
Function
Encode mode
It is the encode mode of video.
H.264: Main Profile encode mode.
H.264B: Baseline Profile encode mode.
H.264H: High Profile encode mode.
MJPEG: In this encode mode, the video needs
large bit stream to guarantee the video definition.
You can use the max bit stream value in the
recommended bit to get the better video output
effect.
H.264: Main Profile encode mode.
Smart Codec
Enable smart codec to improve image compression
performance and reduce storage space.
Note
After enabling smart codec, the device will not support
third stream, ROI, intelligent event detection and other
functions, please refer to the actual interface for more
details.
Resolution
Video resolution. The max resolution of different
channels may be different, please refer to the actual
interface for more details.
Frame Rate (FPS)
Number of frames contained in the video of each
second. The higher the frame rate is, the more vivid and
smooth the image becomes.
Bit Rate Type
There are two options: VBR and CBR.
CBR: bit rate change is very little, the bit rate
changes around the stream value which has been
set.
VBR: The bit rate will change according to the
monitoring scenes.
Note
When the "Encode Mode" is set as "MJPEG", the bit
rate type can only be CBR.
Image Quality
When the "Bit Rate Type" is set as "VBR", it can set the
parameter.
There are 6 levels of video image quality, which are
best, better, good, bad, worse and worst.
Reference Bit Rate
It is to recommend the best stream value range to the
users according to the resolution and frame rate
configured by the users.
Bit Rate
When the "Bit rate type" is set as "CBR", it can set the
parameter.
It is to select stream value according to "Reference Bit
Rate", the bit rate changes around the stream value
which has been set.
Select "Custom" and you can manually set bit rate
value.
