NOTE

►

Converting high-quality video may signicantly increase the CPU loading, and you may encounter

streaming disconnection or video loss while capturing a complicated scene. In the event of such

occurance, we suggest you customize to a lower video resolution or reduce the frame rate to obtain

smooth video.

NOTE:

The bandwidth utilization is configurable 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.

When so congured, the frame-rate-per-second performance can be compromised

in the event of insufficient bandwidth or network clogs. The video quality can be

adjusted to the following settings: Medium, Standard, Good, Detailed, and Excellent.

You can also select Customize and enter a number to designate image quality. The

larger the number, the higher the compression rate, and hence image quality is lower.

A small customized quality number means a low compression rate, and a high quality

image.

- Maximum bit rate - While you want to ensure a reasonable image quality, you can

still impose an upper threshold on the bandwidth taken for the video transmission.

The congurable bit rate ranges from 1mbps to 40mbps.
