Appendix D: Bandwidth and Video Size
The frame rate of video transmitted from the Internet Camera 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 for your Internet Camera.
The required bandwidth depends on content of video source. The slow motion video will produce
smaller bit rate generally and fast motion will produce higher bit rate vice versa. Actual results
generated by the Internet Camera may be varying.

NOTE: Audio streaming also takes bandwidth around 5 kbps to 64kbps. Most xDSL/Cable
modem upload speeds may not even reach up to 128 kbps. Thus, you may not be able
to receive any video while streaming audio on a 128 kbps or lower connection. Even
though the upload speed is more than 128kbps, for optimal video performance,
disabling audio streaming will get better video performance.
