Parameter
Description
recording triggered by events such as alarm
inputs or motion detection alarms.
z
Sub Stream: low resolution video that is
intended for local or remote real-time
monitoring.
Video Compression
Video compression standard, for example, H.264.
The listed options depend on the standards
supported by the camera.
Resolution
Image resolution.
Bitrate Type
x
CBR: Constant Bit Rate (CBR) is used to
maintain a specific bit rate by varying the
quality of video streams. CBR is preferred
when limited bandwidth is available. The
disadvantage is that video quality will vary and
may decrease significantly with increased
motion in the scene.
x
VBR: When using Variable Bit Rate(VBR), video
quality is kept as constant as possible, at the
cost of a varying bit rate, and regardless of
whether or not there is motion in the image.
VBR is ideal when high quality is a
requirement, especially when there is motion
in the picture.
Bit Rate(Kbps)
Number of bits transferred per second. Select a
value or select
Custom
and then set a value as
needed.
Range
Bit rate range. Currently the range is fixed.
Frame Rate(fps)
Number of frames per second.
Image Quality
This parameter is effective only when
Bitrate Type
is
set to
VBR
. Six levels are provided.
I Frame Interval
Number of frames between two adjacent I frames.
I Frame Range
Range of I frames. Currently the range is fixed.
Smoothing
Use the slider to control the sudden increase of bit
rate.
Audio Stream
Enable or disable audio stream.
