Stream2
The Stream2 features the MJPEG compression standard for ROI.
Figure 20. Video & Image / Stream2
MJPEG Setting: Configures the MJPEG setting value for stream2.
Resolution: Specified as the number of pixel-columns (width) by the number of pixel-rows
(height). The Resolution can be adjusted in the range from 320x240 to 720x576. The default
setting is 640x480.
NOTE
The maximum resolution setting might not be obtainable due to programmed compression standard
and processor power.
Bit rate control: The bit rate can be set as VBR (Variable Bit Rate) or CBR (Constant Bit Rate).
-- VBR: Automatically adjusts the bit rate according to the image complexity, using up
bandwidth for increased activity in the image, and less for lower activity in the monitored area.
-- CBR: Allows you to set a fixed target bit rate that consumes a predictable amount of
bandwidth. As the bit rate would usually need to increase for increased image activity, but in this
case can not, the frame rate and image quality are affected negatively.
