Perimeter Security, Part 2
By Bo Perrin

Securing the perimeters of our homes would be relatively easy if not for obstacles. Obstacles come in two general forms. The first form is obstacles placed between the 3rd perimeter circle (furthest out) and the 1st which is the home itself. These obstacles can be man- or God-made. The second form involves the placement of doors and windows in the outer walls of the house structure itself. Both forms block a clear line of sight between the occupant and the furthest portion of the property making it more difficult to protect your family. Additionally, both forms can permit an insurgent(s) the cover he/they need to reach the house structure undetected increasing the level of danger to you and your family.

I will use the house in which I presently live to explore obstacles to perimeter security. I am a minister. I live in a parsonage. The house was built in the mid-40s while the congregation’s meeting house was built around the mid-50s. The church acquired the house a decade or so after it built the meeting house and from the positioning of the structures security was not an issue. Here is a free, very free, hand drawing of the property which is not to scale. I don’t want to read any jokes about how bad are my drawing abilities.


I will begin with obstacles in the yard. The meeting house and house structure sit on a rectangular piece of land that is about 3 or so acres. The road leading to the house is on the east side of the meeting house separating the meeting house from our neighbor. The parking lot for the congregation is on the west side of the building but vehicular access is blocked by gates posted on both the main entrance and a secondary entrance to the parking lot from the access road to the house. The perimeter of the property is lined by a wooden fence, shrubby or trees. The wooden fence is not sturdy and blows over often during a good storm. The trees and shrubby are easily penetrable on foot. The south side of the property is lined by a major street on which an insurgent could easily escape. The west and east sides of the property are lined by homes. The north side leads to a large undeveloped piece of land through which an escaping insurgent can easily be lost. So, the property is porous.

If I look out a window on the north side of the house I have a relatively unhindered line of sight to the tree line. Nevertheless, during the 002summer one of the members of the congregation cut up some tree limbs which fell during a storm. I placed the limbs in piles around a fire pit in the back yard which is itself full of limbs I have yet to burn. The obstacle is temporary. Nevertheless, in its present state it is still large enough to hinder a portion of my line of sight allowing a couple of insurgents to hide behind it.

If I look out a window that points west near the north side of the house two obstacles present themselves. One obstacle is two large trees Obstacles3whose trunks are wide enough for a single insurgent to hide behind. If both trees are used two insurgents could hide themselves close enough to the house structure to make it very difficult for me to detect them until they are right at the house. Further away from the house toward the tree line on the west side of the property is a large wooden barn. The barn poses a serious tactical problem because an insurgent(s) can hide within or without the structure. The barn has two sections with one section completely enclosed. We have had problems in the barn in the past. In every case it was merely teenagers where they ought not to be but the instances revealed a security issue.

Nighttime presents another layer of issues. There is a large light posted on the north side wall of the meeting house. The light throws its rays toward the north. The light illuminates the south side of the trees in the yard but provides a pocket of darkness to the tree’s north side. This pocket is large enough to hide a large male and could be used as a means to sneak up to and come in contact with the house.

If I look out a window that points west but near the south side of the house my line of sight is blocked by a number of trees the west side of the meeting house. The biggest security issue is that at this point I cannot even see the west wall of the garage which without security measures could hide a number of people. The west side of the meeting house is also a security issue. We have had a number of people who merely walked up from the street by the west wall and through our yard. There is almost nothing I can do to enhance the security here. There is a large Obstacleslight on the building’s west wall directed toward the parking lot but it is on constantly and provides no warning. An insurgent could sneak up from the street, hide behind a tree and reach the west wall of the garage. From this position the insurgent could sneak up along the garage’s west wall, turn on to the porch between the house and garage and be at the door without being discovered.

The situation at the front door is no better. There is a porch between the house and garage but it is not enclosed. We have thought about enclosing this area because of weather but the enclosure would certainly increase security. The north side wall of the garage is the only thing you see when you look out the door’s window. It is possible to see the north-east and north-west corners of the Obstacles5garage by relocating yourself in relation to the window. There is a window through which I can see the east wall of the garage clearly unlike the garage’s west wall and it is usually the first area I check when a security light goes off in this general area. The real security issue for this section of the house is the garage’s west wall.

The east side of the house presents a particularly difficult security issue. The house has a lot of windows. Every wall in every room has one to three windows except the east wall. The original house was very small but about twenty to twenty-five years ago the congregation Obstacles6added on to the original structure. The present main bedroom and dining room increased the structure by almost fifty percent. Interestingly, no one decided to put window on the east wall. The security issue is clear. Over the last fifteen years I that have occupied this house there has been a woodpecker who has done all it could to put some peep holes in the wall but with no success. Since there are no doors or windows on this wall there is no access for an insurgent into the house. But without proper security an Obstacles7insurgent could use the east wall to sneak up to the main door. An insurgent could crawl under the windows on the south wall gaining access to the only two doors of the house. The easiest door for an insurgent to cover would be the door between the garage and house since it is used the most. There is no shrubbery to hide behind on the south wall that would permit the insurgent to surprise anyone who walked out that door. The only plant is a rose plant with really big thorns.

These are the security issues I faced when I moved in to this location. Of course, every situation is different nevertheless, the issue is still the same – obstacles in the yard or on the house structure which inhibits a clear line of sight to furthest perimeter.


Securing the perimeter will differ depending on whether we are in a civil or uncivil society. If society has collapsed I would use far more lethal methods of securing the perimeter and my family than under the present situation. Generally, in a civil society the best methods for securing the perimeter and family are loud, bright and leave a legacy.

The first question you need to answer before choosing security measures is, how significant is the threat in my area? Even in a civil society the level of threat differs from place to place. The threat level of where I now live is vastly less than if I were to live in Detroit, MI or Memphis, TN. Memphis is one of the top ten violent cities in America and the general response time for police in Detroit is just under an hour. The Ohio Summit County Sheriffs have responded in less than five minutes to an issue for which I called them at least before the election of the anti-2nd Amendment Sheriff  Steve Barry. The level of threat will determine the measures you will need as well as the price.

One measure is to keep the yard clean. This is simple enough but I have seen yards filled with junk, at least as I see it, which provide great cover for an insurgent to make his or her way to the house structure. Old vehicles, large wood piles and outhouses can be used by insurgents as cover to try to reach the house structure. I seriously need to burn the limbs I have collected in the back yard.

Trip wires are another possibility. Most insurgents will follow closely to the walls of a structure and around the building’s corners. A trip wire can be six or so inches long attached to the building’s corners and a small post. The wire can be connected to some mechanism which will loudly announce to the insurgent that he has been identified. The mechanism could be empty shot gun shell rigged to go off, a can of nails or a flood light. I have also heard you can wire up glow sticks. I can wire the corners of the barn’s west wall, each corner of the house as well as the south-east and south-west corners of the garage.

Another measure is motion sensitive lights. The motion sensitive light, in my case, ought to be placed on the west wall of the barn, the south-west and south-east corners of the garage and on the east wall of the house structure. Generally, motion sensitive lights are useless if located on the structure you are trying to secure because by the time the light goes off the insurgent is already touching the structure. One issue to keep in mind that is oft not discussed is how easy it is to set off a motion sensitive light on one side of the house but run around the house or garage to the opposite side surprising you if you open the door. Check ways first, then proceed. A motion sensitive light ought to be wired to warn of coming danger not that the danger is now next to you.

The final measures I will mention is motion activated video cameras and sirens. Motion activated sirens work like a car alarm using the noise to alert people to the crime and scare off the criminal. Since the noise these measures make is unique among the noises usually heard in most areas I would think they would work well. If where you live is particularly plagued by crime and the possibility of a home invasion is rather high you could install motion activated video cameras. The insurgent’s motion will turn the video on and it will begin to record. These cameras will probably not scare the insurgent off but it would create a legacy for him or her. Additionally, the video feed can be fed onto a website on the internet so (1) you can monitor the insurgent’s movements and (2) you can give the police the location of the feed so that they can monitor the circumstances of the situation and where to look for the insurgent if he or she is still on location. The video measures are relatively inexpensive today. Nevertheless, the cost involved would demand that you use these measures where the risk of insurgent activity is high or cover is more pronounced. Video cameras will work well on the west wall of the barn, the south wall of the garage and the east wall of the house.

The purpose of whatever measures you decide to use is to make each concentric circle of security more difficult to breach by the insurgent the closer he or she gets to the house structure.  As the insurgent attempts to get closer to the house structure (1) the more difficult it ought to become for him to remain undiscovered, (2) the more aware you ought to be of his presence and (3) the level of danger increases for you and your family.
