how to check bandwidth?

[twiggzee]

we are running off board vision processing on our laptop using a m1011 camera set to 320x240, compression 30. we were able to find the targets pretty easily from less than 25 feet away. on bag day, too late of course, we noticed that if we changed our res to 640 x 480 we could see the targets from about 40 feet away.

does anybody know if there is a way to check whether we would go over the bandwidth limit if we did the 640x480 res? is there a way to monitor how much we've used? want to experiment with different resolutions, compression, and fps to see what will best fit our needs.

in the name of procrastination, thanks!!
