Honestly, I would say stay away from wireless 2.4ghz video equipment. It usuallys only works in a line of sight situation. Plus wired is more reliable and the extra money spent for the cable would be well worth it. You can easily and cheaply pickup the equipment needed to split video to multiple monitors from your local radioshack.
A simple way of doing a system like this is to use an RF modulator. You connect your cameras output to the RF modulator input. Then the output of the RF modulator is actually in the form of your common cable tv connector (the F connector). You then take the RF modulator output and send that to an RF splitter. THen from there you run a cable to each of the tvs RF input and when you turn to the
channel that is set on the tv (either 3 or 4) you will get the image on ther tv. You use standard RG-6 cable to connect between the tvs and splitters.
List of equipment:
-RF Modulator $24.99

-short RF cable to go between the Modulator and the splitter $4.59

-100ft RF cable $32.99 x 4

Total= $182.53
Of course if you shop around on the internet or other stores you can find this stuff cheaper. But for the most part this can cost only a little more or could be cheaper then wireless. But what you gain is the confidence in the fact the the system will be reliable.
If you dont have a camera already, you can get one from here:

It costs $139.95, but you can use a standard home video camera as long as it does not have an auto standby feature where if there is not a tape in the camera and recording the camera will shut off. As long as it will stay on that will work for you.
