I once rigged up a camera system at a local golf course entrance that transmitted the color camera's signal perfectly to the club house about 1/3 mile away. You can get transmitter /receivers thru ADI. As far as multiple channels, I no longer do cctv work so I don't keep up but I bet it is quite possible they have equip for that now. After all I can open up multiple pages on my laptop wireless, tune them all into youtube, run several different video's at the same time and see them all onscreen at the same time if I press the f-9 key. There is some noticeable slowing down of the streaming once you get to three video's at the same time, but then again I am not using the most powerful laptop or desktops in the product line either.
