Parameter
Description
Note:
This parameter is effective only when the camera is connected to the NVR
via the private protocol.
Stream
Normal: main stream that is intended for scheduled recording.
Event: main stream that is intended for recording triggered by events
such as alarm inputs or motion detection alarms.
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
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.
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.
NOTE!
The parameters and options displayed may vary with camera model and version.
Some functions may be unavailable if the firmware version of the camera is too low. In this case, you
need to upgrade the camera first.
