Zapping Camera Problem

["ABLE1" <nospamhere@xxxxxxxxxxx>]

Hello all,

Having a problem with continued Camera location being Zapped when a storm
goes by. Over the past couple of years have had to replace a single camera
location with new units after a storm. About six(6) cameras at this point.
There are 2 cameras in this building. The other camera had been zapped as
well before the surge protection and ground rod was installed. Since then it
just the one that has had the continued problem. The cameras are about 40
feet apart.

The following are the other particulars.

> It has always be the video side of the camera that has been hit.
> Building is separated from main building by about 200' of underground PVC
> conduit.
> Cable RG59
> Have installed at the building Ditek Surge Protector DTK-VSPBNCA. One at
> each camera.
> Ground Rod installed within 50' and #12 Ground wire to Protector
> Camera Powered locally with Wall Wart 24vac

I know that this may be impossible but the main question is, what can be
done to stop this from happening??

> Is there a better surge/spike protector??
> Would a second ground rod help??
> Would it make a difference if the camera was powered by 12vdc??
> Is there a way to determine the weak point of the system??

Thanks for any thoughts or suggestions that would be helpful.
