After suffering my first significant lighting strike damage last week, I've been doing some research trying to find a way to minimize my exposure to a repeat of what happened. I have cameras and switches spread out over large areas, with many 500'+ runs between locations. From my home, I have a 300' run to my barn switch. From the barn switch, I have a 500' run to my gate opener switch. From my gate opener switch, I have two 500' runs to PTZ cameras mounted 20' up on utility poles. There is AC at all switches. All cables are unshielded, pure-copper, 23AWG, gel-filled buried cat5e. When the lightning struck near the furthest PoE+ PTZ camera, it made it all the way to the house, killing numerous switches, cameras, and cables. Surprisingly, some of the closest cameras survived unscathed. In any case, at this point I have to replace one of the 500' runs on at the street due to the damage, and I'm stymied on what technology to use that would not only reduce the odds of this type of systemic damage, but is also affordable, and easy to implement within the space constraints of the weatherproof boxes I currently have. Does anyone have any advice on how to secure my installation? I live in middle-TN where storms often include some pretty intense lightning. This installation has been in for almost 2 years, and this was the first hit.
