If we ever truly experience a societal collapse and the law and order we know and take for granted on a daily basis ceases to exit, you might find yourself in need of an early alert system that doesn’t rely on the grid. But how do you go about setting up something like that? It’s actually not as difficult as you might assume. You can, of course make something yourself or even look into purchasing a Dakota Alert Driveway Alarm.
This kind of alarm system is based on motion detection and will provide alerts for you inside the home when movement is detected outside. In a dire situation where things have fallen apart and riots are raging everywhere, it could end up saving your life.
Here’s more on this from The Organic Prepper:
The very first thing I did was find a large pine tree near the entrance of the driveway. I screwed in the motion sensor at an angle that anybody walking past the tree wouldn’t see the sensor until they had already triggered it. The sensor itself runs off of a single 9V battery. If you’re going to be using this as an off-grid system, you’re going to need to have several 9V batteries put away in storage or find a couple of rechargeable ones and have the means to keep them up and running.
Inside the guts of the sensor, you can adjust how sensitive the reading is and the range that the sensor can be tripped. We did discover that it appears the sensor sends out a narrow beam, and you have to be very precise with where you aim it. It took about 15 minutes of toying around with things until it was finally discovered that the little car was driving right underneath the beam. I would recommend aiming the beam right at waist height. That will hit every car that drives by and anybody that is walking too.
The next item to take care of is pairing the censor with the alarm. It’s pretty easy to get this step done. Just consult the manual and it walks you through a series of simple steps. A good pointer from TOP is to choose a “natural sounding” tone for the alarm. She chose one that sounded a lot like a bird, which means it will alert you on the inside, but not those on the outside, which could provide you with the element of surprise.
The range on this is incredible.
I got out to a third of a mile away and was still picking up a signal each and every time the sensor was tripped. I was in pretty wild territory as well. The only reason I didn’t go further out to continue testing was that it was 90+ degrees outside, I was wearing jeans, and I’d spent the past hour walking around with a marine battery in my hand. It was hot. The point here though, is that this will give you plenty of time for an alert system. If the bad guys are on foot and you get an alert a third of a mile away, you have time to get fairly well-prepared. Even if the bad guys are approaching via vehicle, that will still give you a precious minute or two to get your rear in gear.
Another excellent feature of this kind of unit is you can actually link a number of sensors to the alarm system so you can know what’s going on in various parts of your property.
“While I wasn’t able to test this, it appears you can give each individual sensor a different alarm sound as well. That way, you don’t have just one alarm that goes off, leaving you guessing which sensor was just tripped. You could have the coo coo clock for your chicken coop, an alarm for the driveway, and a song for the deer trail. You’d know exactly where to turn your attention,” the article said.
All in all, if you are looking for something that you can use that won’t be connected to the grid, this unit is the perfect choice.
