Appendix B --- Bandwidth Estimation 
 
The frame rate of video transmitted from the IP 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 IP 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 IP 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.
