Appendix B: Bandwidth and Video Size
The frame rate of video transmitted from the device depends on connection bandwidth
between client and server, video resolution, codec type, and quality setting of server. Here is a
guideline to help you roughly estimate the bandwidth requirements from your device.
The required bandwidth depends on the content of video source. The slow motion video will
produce smaller bit rate generally and fast motion will produce higher bit rate. Actual results
generated by the device may vary.

Audio streaming takes up a bandwidth of around 32kbps. Some
xDSL/Cable modem upload speeds could not even reach up to 128 kbps.
Thus, you may not be able to receive good quality video while streaming
audio is also at 128 kbps or lower. Even though the upload speed is more
than 128 kbps for optimal video performance, disabling audio streaming will
get better video performance.
