Re: Long Runs - CCTV

["RTS" <gafa_usa@xxxxxxxxxxx>]

I haven't had the need (yet)
But  I'd go with  Les on this one
Use  Fiber
I have a retail friend locally  who runs fiber from his house to his store
that?s inside then outside then back inside..
He transmits video, data and packet phone all on the same fiber..
Only problem  I know about was him putting the ends on for the
modulator/demodulators.
(hes's also under the footprint of several RF transmitters,  no problem with
fiber)

Bob,

I personally to date have not had to deal with it.  However, if I did or
was going to, I would treat it as computer network. (which it is)
Install Data Switches as hubs. The place your PoE switch or utilize a
local Power Supply near the camera.

Something else I would consider depending on a number of factors would
be to use Fiber.  Placing a Ethernet to Fiber module at each end can
transmit the video data long distances.  It would depend on number of
cameras and the budget.

Again, never had to.................... yet.

Hope that helps.
