Just a few that might give an insight into how ferrites work with RFI on
AC lines..

      Hey Ed,
      <br>
      <br>
      This is some follow up information with the camera issue being
      <br>
      effected by the EMI or RFI lighting at the sign.
      <br>
      <br>
      I decided to try the Ferrite Cores first before the electrician
      changed
      <br>
      the wiring to dedicate or split with wiring feed.
      <br>
      <br>
      I had purchased a set of 20 ea Split Ferrite Cores of various
      sizes.
      <br>
      <br>
      Kind of a long story but I kept adding the Ferrite Cores to the
      hot and
      <br>
      neutral wires feed the sign lights.  First attempt was a total of
      2 per
      <br>
      wire.  It had no effect.  Then added 2 more per wire.  No effect.
      <br>
      <br>
      I was turning on the sign lighting on to check and then off again.
      <br>
      <br>
      Then again added 1 of the largest size per wire and SUCCESS!!!.
      <br>
      <br>
      Then just for a little extra bonus I added 1 more of the largest
      size per wire.  These larger cores had a inside diameter of maybe
      3/8" to 7/16".
      <br>
      <br>
      At this point I was a VERY HAPPY CAMPER!!!!  Then at 5:03 PM the
      lights
      <br>
      turned on for the evening.  And the camera turned off. 
      #*@(&amp;$^#%*@**(#
      <br>
      <br>
      I returned this morning and started adding some of the smaller
      cores.
      <br>
      Inside diameter about 1/8".  After adding 2 ea to hot and neutral
      and
      <br>
      turning on the sign lights, all was good.  I then added another 2
      ea
      <br>
      per wire and left the sign on for the day.  For now all looks
      good.
      <br>
      <br>
      So I now have a total of 9 each on hot and neutral.  If it stays
      good
      <br>
      I am again a HAPPY CAMPER!!!
      <br>
      <br>
      My questions:
      <br>
      <br>
      Do you know, how does the size of the Ferrite Core work into this
      blocking of EMI or RFI for something like this??
      <br>
      <br>
      Is there a relationship between the inside diameter and the
      thickness of Ferrite that plays a role in the effectiveness with
      size of wire??
      <br>
      <br>
      Is there a relationship in the length that has a greater effect??
      <br>
      <br>
      Maybe you don't know the answers to the above but, I am now
      intrigued as to how this Magic worked for me and I am struggling
      to understand exactly how it did.
      <br>
      <br>
      Either way, a big THANK YOU to you for the suggestion.  I really
      do appreciate it.  I would certainly buy you lunch if I knew where
      you
      <br>
      were and I was close.
      <br>
      <br>
      Have a great rest of your weekend.
