Messuring data usage of Web Cameras

Hi Everyone,

I want to be able to measure the data usage between 2 web cameras.

My ultimate goal is to develop an understanding of how much data is used when a bidirectional web camera connection is established.

This is necessary as I do not want to go over my download allowance.

If anybody knows of a good program that can measure the data usage between 2 web cameras it will be greatly appreciated.

Thanks

Davo
