I got a Sony Hi-8 camcorder last summer specifically for videotaping my
coils and other electrical experiments.  I used it to videotape my pole pig
coil last Fall, and despite only being 8-10 feet away from the coil, it
worked fine with no snow.  The only time I got snow was when I tried to
videotape my sparkgap and had to position the camera close to the garage
door.  Everytime a bolt hit the door I would get snow.  Quicktime movies
made from these tapes are on my web site.

That camera was also used for the "cooking with high voltage" section of my
site, in which we simply connected a pole pig to a couple of 100kV caps and
blasted various foodstuffs with it.  This kind of thing can create a lot of
very high frequency interference (and really stress test your caps!), but
once again we had no problems with snow.
