Parameter
Function
Code-Stream
Type
General bit stream.
Compression
There are three options: H.264 (main profile
standard, H.264H (high profile standard), H.264B
(baseline standard) encode and MJPEG encode.
The H.264, H.264H and H.264B both are H264
bit stream. H.264 is the Main Profile encode and
the H.264B is the Baseline Profile encode
mode. H.264B is for Blackberry cell phone to
realize the monitor. You need to enable the sub
stream function in your camera and set the
resolution as CIF. Then you can monitor via the
Blackberry cell phone.
MJPEG: In this encode mode, the video needs
to large 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.
Image capture
size
There are multiple resolutions. You can select from
the dropdown list.
For each resolution, the recommended bit stream
value is different.
Frame
rate(FPS)
NTSC: 1-30fps. PAL: 1-25fps
The frame rate may vary due to different resolutions.
Transmission
Priority
There are two options: VBR and CBR.
Please note, you can set video quality in VBR mode.
Reference Bit
Rate
Reference bit rate value according to the resolution
and frame rate you have set.
Bit Rate
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.
Please refer to recommend bit rate for the
detailed information.
Refresh
interval
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.
