Please refer to the following sheet for detailed information.
Parameter
Function
Main
stream
Bit stream type
It includes general 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.
Encode mode
There are three options: H.264 (main profile standard),
H.264H (high profile standard), H.264B (baseline
standard)encode and MJPG encode.
 H.264 ：Main Profile encode mode.
 H.264H : High Profile encode mode.
 H.264B ：Baseline Profile encode mode
 MJPEG ：In this encode mode, the video needs
larger bit stream to guarantee the video definition.
You can use the max bit stream value in the
recommend bit to get the better video output effect.
Resolution
There are multiple resolutions. You can select from the
dropdown list.
For each resolution, the recommended bit stream value
is different.
Important
You can not set a resolution higher than 720P (not
including 720P) when the flip function is in process.
Frame Rate
PAL: 1～25f/s，NTSC: 1～30f/s..
The frame rate may vary due to different resolutions.
Bit Rate Type
There are two options: VBR and CBR.
Please note, you can set video quality in VBR mode.
Reference Bit
Stream
Reference bit rate value according to the resolution and
frame rate you have set.
Bit Rate
 In VBR, the bit rate here is the max value. In CBR,
it is a fixed value.
 See reference bit stream for recommended value.
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.
