Issues are dead products. Not just the cameras. Wire running through the ground outside the house (even in conduit) is a lightning magnet. It will run back in the house and potentially destroy an entire system through the comm ports. I’m in the Appalachian mountains with a rural power grid where most of the lines are above ground. Add in the high mineral deposits in the ground, and the fact that the customer will want the cameras actually on or close to trees to help camouflage them.
Civil War reenactment is LARPing for people with no imagination.
