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”,
“Constant bit rate”, and “Fixed quality” for MPEG-4 mode and “Maximum frame rate” and “Fixed
quality” for JPEG mode on the Audio and Video Configuration page, are correlative to allow for
achieving the best performance possible.
For Viewing by Mobile Phone
Most 3GPP cell phone supports media streaming with MPEG4 video and GSM-AMR audio. Due
to the limitation of the bandwidth for 3GPP, only 176x144 video solution will be supported for cell
phone viewing. Please set related video settings first as mentioned when viewing by mobile
phone.
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 “Constant bit rate” to 1000Kbps or 1200Kbps, or set “Fixed quality” at the highest
quality. The maximum frame rate is 30. If your network bandwidth is more than 512Kbps, you can
adjust the bit rate according to your bandwidth and set the maximum frame rate to 30 fps. If the
