Video quality

Constant bit rate:

• Constant bit rate: A complex scene generally produces a larger le size, meaning that

higher bandwidth will be needed for data transmission. The bandwidth utilization is

congurable to match a selected level, resulting in mutable video quality performance.

The bit rates are selectable at the following rates: 20Kbps, 30Kbps, 40Kbps, 50Kbps,

64Kbps, 128Kbps, 256Kbps, 512Kbps, 768Kbps, 1Mbps, 2Mbps, 3Mbps, 4Mbps,

6Mbps, and 8Mbps� You can also select Customize and manually enter a value�

• 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 drag the slide bar to

change the quality setting�
