Whether you need to secure your home, campsite, or bug out location, setting a survival perimeter alarm is vital. This is the process up putting systems in place that will keep unwanted people or animals from entering your area. There are several different layers of protection that you can use for a perimeter alarm, and each serves a different purpose. Whether you want an elaborate system of protection or something simpler, it is vital that you set a perimeter as soon as you get settled in your given area.
Where to Set your Survival Perimeter Alarm
When you first decide to set a perimeter around your area, you may not be sure exactly where that perimeter should be. You must think about your perimeter from the perspective of needing to defend your area. Your perimeter should be close enough to your location that you can see the whole line. However, far enough that there is a safe distance between you and the perimeter. The perimeter is the point where you may decide to shoot at an intruder, so it should be within gun range. You also must consider the length of the perimeter and be sure that you have enough resources to get everything set.
1. Survival Perimeter Barriers
One of the simplest and most common ways to set a survival perimeter is to create a barrier at that perimeter. This could consist of a fence or wall, or you can use natural materials. The barrier is intended to discourage intruders from entering, or to slow them down. You want the barrier to be obvious so that they will see it and hopefully decide to move on. If they do decide to enter, it should take some time to get through the barrier so that you can fire upon them if needed.
We have a barbed wire fence at the edge of our property that works well for this. Unless a person has wire cutters, they are forced to climb the barbed wire. Often they get snagged, and it can take some time to get over the fence. A barrier can be as simple as a pile of logs or thorny branches. You can also use the features of a landscape to help with your perimeter. If you make camp next to a cliff or rock face, then that feature can serve as part of your barrier.
2. Early Detection Systems
It is also important that you are alerted when an intruder reaches your perimeter. You may not have the manpower to keep somebody on watch 24/7, so an early detection system is vital. These can be elaborate, or you can DIY your system. There are all kinds of cameras and alarms that are set up on motion detectors and can be installed near the perimeter. You can also use something as simple as a motion detector light to alert you of movement on the perimeter. Just be aware that anything from the wind blowing branches to a squirrel can set these off.
You can also set up a variety of different tripwire systems for early detection. The tripwire is run around the perimeter and is typically suspended one to two feet off the ground. You can set it up to just rattle a can with some rocks in it, or you can get more creative. Trip wires can be rigged with sirens, firecrackers, or anything else that makes noise to get your attention.
3. Guard Duty
Your third layer of protection should be a rotation of lookouts to keep an eye on the perimeter. If possible, you want to have a rotation so that somebody is watching the perimeter at all times. If this is not possible, focus on keeping watch after dark. Ideally, your guards should have a gun just in case they are forced to fire upon an intruder. You can also use dogs to help you keep track of your perimeter. You can do this by letting them roam or chaining them near the line.
Your perimeter is your first line of defense against intruders. Without a good perimeter, you could wake up with a gun in your face or with a bear chewing on your leg. A perimeter deters unwanted guests, slows them down, and warns you that they are coming. With the right systems in place, it even gives you a chance to fire on threats before they get close enough to do any damage. Whenever you make camp or settle into your location for the evening, take the time to ensure that your perimeter is set and functional. It could save your life.
