You could use a couple of looping quads, one dedicated to each TV. Take the
quad's outputs to the TV's composite video input, and forget modulators.

Mini-coax will make cabling easier.

Here's a pretty good hi-res bullet camera with IR's, and you can order them
with  4mm fixed, 3.8~9.5mm or 2.5~6mm varifocals.
