Maximal Bit Rate: When the actual bitrate exceeds the specified
Maximal Bit Rate, the system will automatically lower its bitrate so as
not to exceed it. Select one of the bitrates from the drop-down list or
select
Auto if you do not want to enable this function. The default
maximal bitrate values are detailed as follows:
Camera Type Default Max. Bitrate of VBR
Stream 1 6 Mbit
1.3 MP
Stream 2 4 Mbit
Stream 1 8 Mbit
2 MP
Stream 2 4 Mbit
Stream 1
3 MP / 4 MP / 5 MP
Stream 2
12 Mbit
Stream 1
8 MP / 12 MP
Stream 2
16 Mbit
Note: For GV-BX2600, the default maximum bitrate for Stream 1 is set to
6 Mbit. When the video format of Stream 1 and 2 is set as MJPEG, the
options for bitrate setting will be hidden automatically.
„
CBR (Constant Bitrate): CBR is used to achieve a specific bitrate by
varying the quality of the H.264 / H.265 stream. Type the bitrate or
select one of the bitrates from the drop-down list.
„
Smart Streaming: When the option is enabled, the bitrates will be
automatically reduced in static scenes, significantly maximizing
bandwidth and lowering file size.
You can choose the image quality of Static Scene and Dynamic
Scene to one of the 5 standards: Standard , Fair , Good , Great and
Excellent . You can even choose the maximum bitrate to optimize the
bandwidth.
