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
