Re: Zapping Camera Problem



Able1,

surprisingly enough,  we've had the same kind of problem  you described
originally..
Our "fix",  least wise  it's stopped 99% of all replacements ,  was to float
the long runs of coax above ground.. (no grounding at the camera end)
use double surge/lighting arrestors, one at the entry point to the primary
building another at the recorder.

Our thinking was to reduce or remove the current/voltage surge between
grounds, and only deal with the transients air born   antenna effect..
so far (3 years)  its been working..

NOTE:  you'll need to check the surge protectors after any events at the
building location..
(you might stop the first one  but if its damaged the next strike  will get
your cameras again..)


Ideally,  you should run your Cat 5/6 in buried METAL conduit between the
buildings,  with Transient Surge protection at both building entry points
which are ground bonded to the structures ground system..  (ie... the
electric code  NFPA 70  or  IBC)

But unless it?s a new construction,  good luck with that..

RTS
