I have a barn about 100 meters from my house where I plan to install a
video camera to monitor a mare about to foal in March.  I would like to
get the signals from the barn to the house so that we can watch from a
heated area.  I have signal cables from the barn to the house already,
with multiple extra pairs, both twisted and non-twisted; however, no
coax installed, and I can't put that in now because the ground is frozen.

So...
  1. Can I send the audio/video signals across twisted pair with an
     acceptable amount of loss/crosstalk?  Should I send it as raw video
     and audio, or modulated to channel 3?
  2. Are there other ways that might work better, such as an infrared
     link or some sort of RF link?  I have seen the VCR Rabbit but it
     lists range as 150 feet "under ideal conditions".  Could I add 
     bigger antennas to it and make it work?  The nearest neighbor is
     over 1/2 mile away so RF interference should not be a problem if
     the power is low enough.

Any help would be appreciated...
  Greg
