Appendix D: Bandwidth
Estimation
The frame rate of video transmitted from the Network Camera depends on connection
bandwidth between client and server, video resolution, and quality setting of server.
Here is a guideline to help you roughly estimate the bandwidth requirements form your
Network 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 Network Camera may be varying.
Image Resolution Average range of Data
Sizes for JPEG mode
Average bit rate for MPEG4
mode
160 x 120 (QQVGA) 3 ~ 6k byte per frame 100kbps~256kbps @ 30fps
320 x 240 (QVGA) 8 ~ 20k byte per frame 300kbps~600kbps @ 30fps
640 x 480 (VGA) 20 ~ 50K byte per frame 400kbps~1000kbps @ 12fps
Note: Audio streaming will take bandwidth around 32 kbps. Most
ADSL/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.
