11 Appendix D: Bandwidth Estimation
74
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 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 device may be varying.
Bandwidth Estimation for 3 MEGA Mode
Image Average range of data sizes for
Resolution MJPEG mode
320 x 240 8 ~ 20k byte per frame
640 x 480 20 ~ 50K byte per frame
1280 x 960 100 ~ 300k byte per frame
2048 x 1536 400 ~ 1200k byte per frame
Bandwidth Estimation for 2 MEGA Mode
Image Average range of data sizes for
Resolution MJPEG mode
320 x 180 8 ~ 20k byte per frame
640 x 360 20 ~ 50K byte per frame
1280 x 720 100 ~ 300k byte per frame
1920 x 1080 200 ~ 800k byte per frame
Note: Audio streaming also takes bandwidth around 32kbps or 64kbps. 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 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.
