the bit rate according to your bandwidth and set the maximum frame rate to 25 fps or 

30 fps. If the images vary dramatically in your environment, you may want to slow the 

maximum frame rate down to 20 fps in order to lower the rate of data transmission. 

This allows for better video quality and the human eyes cannot readily detect the 

differences between those of 20, 25, or 30 frames per second. If your network 

bandwidth is below 384 Kbps, set the “Fix bit rate” according to your bandwidth and try 

to get the best performance by fine-tuning with the “Maximum frame rate”. In a slow 

network, greater frame rate results in blur images. Another work-around is to choose 

“Half” in the “Size” option for better images, or “Halfx2” for a larger image view. Video 

quality performance will vary somewhat due to the number of users viewing on the 

network; even when the parameters have initially been finely tuned.    Performance will 

also suffer due to poor connectivity because of the network’s burst constraint. 

Only Quality Images Will Do 

To have the best video quality, you should set “Fix quality” at “Detailed” or “Excellent” 

and adjust the “Maximum frame rate” to match your network’s bandwidth. If your 

network is slow and you receive “broken” pictures, go to the TCP protocol in 

“Connection type” and choose a more appropriate mode of transmission. The images 

may suffer a time delay due to a slower connection.    The delay will also increase with 

added number of users.     

Somewhere Between Real-time and Clear Images 

If you have a broadband network, set “Fix quality” at ”Normal” or better, rather than 

setting “Fix bit rate”. You can also fix the bandwidth according to your actual network 

speed and adjust the frame rate.    Start from 30 fps down for best results but not below 

15 fps.    If the image qualities are not improved, select a lower bandwidth setting.
