• Fixed quality: On the other hand, if Fixed quality is selected, all frames are
transmitted with the same quality; bandwidth utilization is therefore unpredictable.
The video quality can be adjusted to the following settings: Medium, Standard,
Good, Detailed, and Excellent. You can also select Customize and manually
enter a value.
Maximum bit rate: With the guaranteed image quality, you might still want to place
a bit rate limitation to control the size of video streams for bandwidth and storage
concerns. The configurable bit rate starts from 1Mbps to 40Mbps (Fixed quality).
You may also manually enter a bit rate number by selecting the Customized option.
The Maximum bit rate setting in the Fixed quality configuration can ensure a
reasonable and limited use of network bandwidth. For example, in low light conditions
where a Fixed quality setting is applied, video packet sizes can tremendously
increase when noises are produced with electrical gain.
