Parameter
Function
Channel
Please select a channel from the dropdown list.
SVC
SVC is so called scaled video coding. Check the box to enable this function.
During the network transmission process, system discards unimportant
frames when the bandwidth is not sufficient or the decode capability is low. It
is to guarantee video quality and transmission fluency.
Video enable
Check the box here to enable extra stream video. This item is enabled by
default.
Code
stream
type
It includes main stream, motion stream and alarm stream. You can select
different encode frame rates form different recorded events.
System supports active control frame function (ACF). It allows you to record
in different frame rates.
For example, you can use high frame rate to record important events, record
scheduled event in lower frame rate and it allows you to set different frame
rates for motion detection record and alarm record.
Smart Codec
Select Start from the dropdown list to enable smart codec function. The DVR
can auto reduce the video bit stream of the non-important surveillance
object to save the storage space. Please note this function is for main
stream only.
Compression
Compression: System supports H.264H, H.264, H.264B, and MJPEG.
H.264H: It is the High Profile compression algorithm. It has the high
encode compression rate. It can achieve high quality encode at low bit
stream. Usually we recommend this type.
H.264 is the general compression algorithm.
H.264B is the Baseline algorithm. Its compression rate is low. For the
same video quality, it has high bit stream requirements.
Resolution
It is to set video resolution. The higher the resolution is, the better the video
quality is.
Frame Rate
PAL:1
~
25f/s; NTSC:1
~
30f/s.
Bit Rate
Main stream: You can set bit rate here to change video quality. The
large the bit rate is, the better the quality is. Please refer to recommend
bit rate for the detailed information.
Extra stream: In CBR, the bit rate here is the max value. In dynamic
video, system needs to low frame rate or video quality to guarantee the
value. The value is null in VBR mode.
Reference
bit
rate
Recommended bit rate value according to the resolution and frame rate you
have set.
I Frame
Here you can set the P frame amount between two I frames. The value
ranges from 1 to 150. Default value is 50.
Recommended value is frame rate *2.
