Layer 0: A gate across the only access road about a quarter mile from the house. Most of the time this gate is locked open, so I don't really count it as a layer, but it is there 'just in case.' I'll be adding a wireless motion detector system at this gate soon (Dakota Alert), and perhaps a wireless intercom as well since it is out of sight of the house.
Layer 1: Motion detectors outside the perimeter fence (Chamberlain) with the receiver in the living room.
Layer 2: A six-strand high tensile electric fence around the perimeter of the property. This has not been gated in the past, as our driveway has been open through it. I am in the process of hanging a gate at that entrance now, however. And I have a solar powered motion detector floodlight ready to put up there also, as soon as I get home with a 10' 4X4" post. This gate will be about 150 yards from the front door.
Layer 3: A 47" stock fence with a strand of high tensile hotwire top and bottom. There's a padlocked gate where the driveway comes through this fence. This gate is 51 yards from the front door.
Layer 4: Motion detectors inside the inner fence (Chamberlain) with the receiver in the bedroom where we sleep.
Layer 5: Motion sensor lighting around the house.
Layer 5 1/2: A 6' wooden privacy fence around the back of the house. The gates stay closed and latched. At the front door there's a 10'X16' deck with a 4' railing around it. There's a ramp on one side and steps on the other, and there are gates at the top of the steps and the ramp that can be locked.
Layer 6: Ordinary doors and windows, alarmed with magnetic reed switches.
Layer 7: Two Fila Brasileiros and a Brittany spaniel.
Layer 8: Several Remington 870s and a couple of AR carbines in handy locations in the house, while someone is home- if we both depart, the guns go back in the safe. Both DW and I carry with NC CCH permits both in the home/on the property and elsewhere where it's legal to do so.
