There's a very deep question lurking.  We more or less take on faith
that cables that are outside are dangerous and ones entirely inside are
safe.  But the house is often not a sealed metal box.  I'd be interested
in comments from people who understand better.

But, it does make sense to me to treat the Ethernet cable to the camera
the way that code requires antenna coax to be treated, as it's not so
different from the lightning viewpoint.
