I've been asked to figure out how to run video from a camera on stage, to a video switch in the booth, then to a projector on main pipe. What concerned me was the long run, which we've had trouble with last year. Last year we tried to send video from the booth to main pipe with coax cable, but the video signal wasn't strong enough. We ended up using an old VCR in the booth to modulate it into RF channel 3, and another VCR clamped to the pipe tuned to ch. 3 and connected to the projector. Ugly, but the video got through.
The system with the VCRs is still in place, but I'd like to be a bit more professional this time (and we don't have two extra VCRs for the camera run). A search on CB leads me to believe that the best solution is either to use coax cable with BNC connectors (with RCA adapters), or to use video baluns with cat5 cable. I'm leaning toward the baluns and cat5 cable, because last year's run with coax didn't work. Could it be that we just used cheap cable?
I've been asked to figure out how much all of this will cost. In my searching, I gather that I can rent high-end BNC coax cable. Can I rent the baluns and cat5 too, if they are the best solution? I'd like to rent as much as we can to keep our costs down. Can anyone recommend anyplace in Rhode Island that we can rent from? (note that we already have the camera)
Just to recap, the signal originates at the camera, goes 100' (plus slack so the cameraman can walk around) to the video switch in the booth (a passive device), then proceeds another 100' to the projector on the main pipe.
Also, about the term "main pipe". It doesn't seem that anyone here uses that term, but at our venue it refers to the lighting truss that hangs FOH, just downstage of the end of the stage. What's the actual term for it? Would it just be the 4th electric?
I appreciate your help, I haven't actually worked with video (or renting) very much and this is a bit new to me.
