If you're worried about bandwidth, I would look into capping the frames per second the camera transmits or the resolution. I know the Axis cameras had a configuration utility page that allowed this sort of customization.

If I'm not mistaken converting to grayscale reduces bandwidth because of the number of channels it transmits. With a standard rgb image, you have three channels per pixel. Each of these channels has value. For a grayscale image however you only have one channel. Now two extra channels on one pixel would not do much in terms of performance but once you have a few hundred extra it can especially when you try to get that image to send almost instantaneously .
