Here is a guide to help you understand the bandwidth requirements for your camera. 
 
Bandwidth is equal to the average frame data size in kilobits multiplied by the average 
frame rate in frames per second. Frame data size, or the number of bits comprising a 
single video frame varies a great deal from depending on scene complexity and lighting conditions. This is due 
to the variable nature of JPEG image compression. Shown below are some average figures. Your results may 
vary. 
 

Image Streaming Size 

Average range of Data Sizes 

160 x 120 

32 - 48 kilobits 

320 x 240 

64 – 96 kilobits 

640 x 480 

320 – 480 kilobits 

 
For example, streaming 4 fps of 160 x 120 video requires 128 to 192 kbps (kilobits per second). Therefore, with 
a 128K upload connection; you will typically see 3 to 4 frames per second with 160 x 120 and 1 to 2 frames per 
second with 320 x 240.

Note: Audio streaming requires 128 kbps. Most DSL/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 connection. 
 
For optimal video performance, disabling audio streaming will result in the best 
performance.
