Low Cost Alarms and Early Warning Systems for Preppers

Low Cost Alarms and Early Warning Systems for Preppers by Patrick F – The Survivalist Blog

Alarms are usually one of two types, audio, or visual, although some can be a combination of the two. Alarms are also great resource if used effectively and acted upon when triggered. They allow an extra layer of protection/defense especially if one is short of personnel. Placed effectively alarms can enable a single person to monitor a much larger area than would normally be possible.

While there are many types of alarms and alarm systems available, many are expensive and often require a power source to run and operate. Some systems can even be custom designed and built for an individual’s specific situation and needs. If you have the resources to obtain one of these systems that’s great. I however do not. So I have found and/or made other less expensive, yet still reliable setups. Now please don’t assume these less expensive or homemade setups are useless. I have personally used these on my own property as well as using them in paintball and other more specific simulations, and I assure you they are reliable and effective.

So with that in mind let’s start off with some inexpensive alarms that can be easily purchased and then I will detail some homemade alarm systems. With both I will begin with systems that can be used at a distance and then we can move to shorter range setups. Also I am going to make the assumption that you will be in a position to observe or hear the alarms when they are tripped.

One unit I particularly like is the wireless drive way alarm manufactured by Bunker Hill as well as others. These units run on batteries and usually cost around twenty dollars or less. The sensor unit takes a nine volt while the receiver unit takes three C Batteries. Range for this unit is listed at 400 ft. with both of the units being weatherproof. Range is variable depending upon terrain although I have used these units at several hundred feet both in sight and out of the line of sight.

Beside the advantages of the unit being wireless and weatherproof, they also work well at night and during the day. Also since the sensor and receiver are two separate units, anyone tripping or activating the sensor does not know that they have d0one so as the signal is sent to the receiver.
