I need a system that allows me to send S-Video wireless from a camera to the back of a switcher. Any suggestions. I know I have seen it done before but can't find any products out there.

I'm assuming your sending the signal to monitor what is recording as opposed to recording the actual signal. If so and the distance is under 50 feet or so, there are a lot of consumer products made for in home use that are only about $40 or so and work great, also with S-video. Just look at websityes such a radioshack or the source for wireless audio video products. Not sure if that is what your looking for but if so, its a place to start looking.

It's anywhere from 50 to 100 ft. I am sending a roving camera to a switcher that we are producing a live show with.
