Guys, the OP is building a privacy wall, not an electrified security perimeter.
I can understand that. Before we built ours, I can remember seeing a line of chairs facing our property from the front and one side. We used to feel like we were their late afternoon and evening entertainment (few tv owners in our campo). These days we sometimes see 3-4 kids poking their heads over the wall when we have guests, sometimes they climb up and sit on top. A LOT of people live on the property next door, and they weren’t happy when we built the wall, even threatened to knock holes in it because they were sure it was going to make their homes flood when it rained. 🤦♀️
