Tune the best performance
The best performance means the image refresh rate should be the fastest as possible
and the video quality should be the best as possible at the lowest network bandwidth
as possible. Three factors, “Maximum frame rate”, “Fix bit rate”, and “Fix
quality” in the Video configuration page, are correlative to the performance.
My priority is real-time motioned images
To achieve the real-time visual effect, the network bandwidth should be large enough
to transmit 20 image frames or more. If you are in the broadband network over 1 Mbps,
you can fix the bit rate to 1000Kbps or 1200Kbps, or fix the quality to achieve the
maximum frames. The maximum frame rate is 25 in 50Hz system and 30 in 60Hz
system. If your network bandwidth is more than 384Kbps, you can fix the bit rate
according to your bandwidth and set the maximum frame rate to 25 or 30. If the
images vary dramatically in your environment, you may slow down the maximum
frame rate to 20 to decrease the transmitted data for better video quality since human
could not easily tell the difference between 20 and 25 or 30 frames per second. If your
network bandwidth is below 384 Kbps, you should fix the bit rate according to your
