Fine-tuning for Best Performance

Best performance generally equates to the fastest image refresh rate with the best

video quality, and at the lowest network bandwidth as possible. The three factors,

“Maximum frame rate”, “Fix bit rate”, and “Fix quality” on the Video Configuration page,

are correlative to allow for achieving the best performance possible.

For Best Real-time Video Images

To achieve good real-time visual effect, the network bandwidth should be large enough

to allow a transmission rate of greater than 20 image frames per second. If the

broadband network is over 1 Mbps, set the “Fix bit rate” to 1000Kbps or 1200Kbps, and

set “Fix quality” at the highest quality. The maximum frame rate is 25 in PAL system

and 30 in NTSC system. If your network bandwidth is more than 384Kbps, you can fix
