Hi Ken,
The reason I connected the screen to the camera chassis was to ensure no possibilities of erratic behaviour from interference being picked up with long lengths.
Remember that I'm running 10m at the moment with hopes of making it 20m soon.
Also, if you're in an area that gets a bit of lightning, it will help too.

You don't have to earth the screen for short runs (2m) but then it is also not necessary to use screened cable.

If you do intend to run long lengths, I recommend screened cable with the screen connected to any of the little screws holding the chassis together. (The "Earth" terminal on the outside of the camera is simply connected to the chassis internally)

DO NOT use the screen as one of your conductors (such as the "common" wire)
This will ENSURE that your cable becomes a big antenna that may pick up signals from elsewhere and cause erratic camera behaviour when in the menu.

Regards
Martin
