Can anyone help me understand what would be the requirement, preferably
worldwide worst-case if possible, for connecting the outer conductor ("shield")
of the coaxial cable (RG59) in a security-camera application? The cable can be
up to 2000 ft (~ 600m) long, between the central unit (inside the building) and
the remote camera (anywhere within the reach). The application can be anything
from industrial to apartment buildings.
Can I (or do I have to) connect the outer conductor to the safety ground
(enclosure) on both ends? .. on one end (which?), etc.
Alternatively, do I need to provide safety isolation from the outer conductor
to the safety GND (enclosure?), how much, on which end, what kind of caps to
GND can I use for EMI if I need safety isolation, etc.?
I am asking strictly from the safety/regulatory hard requirement point of view,
not trying to discuss which would be better for EMC. Is there an simple answer?
Did I miss any key info or question?
Thanks, Neven
