Thanks VST_Man!
I knew that there was something obvious that was the problem. I'm also sure that this is a core idea to understanding how these systems work, but I still wish that the documentation that came with the camera would have mentioned this, even if just one line: Note: Hey dummy, this signal is not modulated, so get an appropriate monitor or a modulator.
I don't need a quality signal, just something that lets me view the recordings quicly and easily as I need to. It sounds like a cheap modulator is an easy approach to try so that I can see if it is good enough.
I will figure out which cat is peeing on my clothes!!!
Thanks again!
