Video 

Resolution 

Specify video resolution of MPEG4 video encoder. Available 

options are VGA and QVGA resolution. VGA resolution 

provides more details than QVGA, but requires more 

network bandwidth. 

Video Quality 

Specify video quality. There are two video quality types: 

CBR (Constant Bit Rate), and VBR (Variable Bit Rate); 

CBR: The video bit rate is fixed, you can select a bit rate 

from dropdown menu. Higher bit rate means better video 

quality. But if your network bandwidth is limited, select a 

lower bit rate will help. 

 

VBR: Video bit rate is variable based on the video content 

being transferred. There’re 5 levels of setting from “Lowest” 

to “Highest”. Select “Lowest” will lower video quality and 

save network bandwidth; if a better video quality is required, 

select “High” or “Highest”. 

Video Frame 

Rate 

Specify video refresh rate of MPEG4 video encoder. Higher 

video refresh rate provides more details about motion, but 

requires more network bandwidth. 

 

CAUTION: Choosing a low frame rate will save bandwidth, 

but may not be able to capture every motion if the object that 

IP camera points to is moving too fast. 

Click “Apply” to save settings and make the new settings take effect. 

3.3.3 MJPEG 

If you selected “MJPEG” as the video encoding format of this IP camera, you 

can specify the parameters of MJPEG video encoder here.
