Bandwidth Calculator:

The estimated bandwidth required is for the normal working conditions. If you cannot meet it, the system will continue to perform. However, the desktop sharing speed will become slower and some webcams may not display or display in poor quality. The rule of thum is that the minumum bandwidth should not be less than 20% of what the calculator suggests. Each webcam should provide at least 64 Kbps bandwidth in order to have it work.
