A friend had the vertical snowy dots problem with his camera.
Wrapping the camera in grounded Al foil cured this problem.  
The e-field from the secondary is usually the culprit.

On my last coil I mounted a mini-CCD in the vault, looking up
the manway at the primary.  I have only lost this camera once.
