Appendix C: 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.

1920 x 1080 200 ~ 500k byte per
2048 x 1536 300 ~ 750k byte per
Audio streaming also takes bandwidth around 32kbps. Some xDSL/Cable
NOTE:
modem upload speeds could not even reach up to 128 kbps. Thus, you may
not be able to receive good quality video while also 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.
