I saw (many years ago), pictures of video cameras mounted on the edge 
of an eme dish for just this purpose.  I also remember (from some 
amsat meeting) a picture of someome's shack which had a TV monitor 
with the moon in the center of it.

Only concern i'd have is that a TV camera is an electronic device, 
which generates EMI.  Mounting such a thing so close to your antennas 
may cause some or possibly a huge amount of interference.  I'd 
suggest making sure you can cut power to the camera remotely, and 
also can disconnect the cable that carries the TV signal down to the 
shack.  Whether that cable is a coax or an ethernet or whatever, it 
can carry EMI from equipment in the shack up to the antenna.
