2.4.2 MPEG4
If you selected ‘MPEG4’ as the video encoding format of this IP camera, you can specify the parameters of MPEG4 video encoder here.
The descriptions of every setting in this menu will be given below:
Item | Description |
Video Resolution | Specify video resolution of MPEG4 video encoder. Available |
| options are VGA, QVGA and QQVGA resolution. VGA |
| resolution provides more details than QVGA/QQVGA, 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 | Specify video refresh rate of MPEG4 video encoder. Higher |
Rate | 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. |
