[I frame interval]
: adjustable between 5
~
200.Smaller I frame interval means higher image bitrate
and better image quality. It is recommended to set the I frame interval as above 25.
[Frame Rate]
: set encoding frame rate per second. Under poor network condition, frame rate can
be reduced to control encoding bitrate to make motion images flow more smoothly.
[CBR/VBR]
: CBR and VBR are optional. CBR adopts constant encoding bitrate, VBR adopts
variable encoding bitrate.
[Bitrate]
: the range of preferred and alternate stream is 30~16384Kbps.Higher bitrate setting can
generate better image quality, but it occupies more bandwidth, please adjust the setting according
to your actual bandwidth.
Under CBR setting, [Bitrate] is the constant bitrate of encoding.
Under VBR setting, [Bitrate] is the variable bitrate of encoding.
[Image Quality]
: under CBR setting: set the bitrate range via “Image Quality”, 1 means it is
controlled by the software.
Bitrate range, 2~6 means corresponding bitrate range is ±10%
~
±50%
Under VBR setting: set image quality via “Image Quality”, smaller value of image
quality means better quality and higher bitrate, but the bitrate will not
exceed its set value.
[LAN default value]
: I frame interval: 100, frame rate: 25, bitrate: VBR, 2048kbps, image quality:2
[WAN default value]
: I frame interval: 25, frame rate: 5, bitrate: CBR, 384kbps, image quality:4
Note: Non-professional users please use “Advanced Settings” with caution
[Auto Iris Level]:
adjust the control level of auto-iris to control the illumination of lens iris.“-”: reduce
illumination of auto-iris, “+”: increase illumination of auto-iris.
Works only on auto-iris lens.
[Auto]
: select this button when using auto-iris lens.
[Manual]
: select this button when using manual-iris lens.
[Auto White Balance]
: select this button to realize automatic adjustment of white balance.
[Auto Gain Control]
: Enabling auto gain will improve the effect of images under low illumination.
[Back Light Compensation]
: When there is strong light behind the monitored objects, illumination
compensation will be provided in the required range to get better image quality.
[Video Masking On/Off]
: enable or disable video masking.
[Masking Area Setup]
: right click and move cursor to set image masking area, an image can be
entirely or partially masked, maximum 4 areas supported.
[All]
: mask the whole image.
[Clear]
: clear masked areas.
[Parameter setup for snapshot function]
: supports only images of JPG format currently, definition is the
same as set in
[video definition]
.
[Audio on/off]
: turn on or turn off the audio of IP camera, users can choose MIC or linear input,
When there is no need for audio, close audio input to save DSP resource and network resource.
Audio is disabled by default.
[Sample rate]
: Supports audio sample rates of 8k and 32k.
