I have film Tesla coil activity for about 8 years now.  I have always 
used VHS-SVHS cameras all used CCD imaging chips and in the hundreds of 
hours of filming Tesla coils, high voltage, high energy phenomena, I have 
never had a problem.  At very close ranges to larger systems a bit of RF 
noise creeps into the image, but no damage is done to the camera.  The 
key is to use batteries only while filming and avoid a tripod if possible 
(although, I have used them.)  Any metal objects touching the camera is 
an invitation to disaster around large systems.

I have noted that in this day of cheaper construction, especially the 
little cheap 8mm camcorders or "palm-corders", that the shielding of the 
circuitry is terrible.  In a couple of instances,  I have had visitors 
with these cheapo cameras visit the lab, and the coil shut the cameras 
off as if the pause or stop button had been pressed.  They were literally 
unable to record due to this anomolous behavior.
