Why Do My Cameras And PoE Midspans Keep Getting Fried?

Hello, we have a major issue on our hands.

At a roadside "rest area" we have axis ptz cameras with axis poe midspans.

In the last year we have had approx 7 cameras and 16 midspans killed by some type of electricity.

We had electricians go out... they say the poles are grounded and see no problem.

They tested the backup generator and see no problem.

They wanted me to ask if Axis equipment is especially sensitive to electricity.

Any tips??? thanks!!!
