(Continued from Part 1.)
The final aspects you need to consider when planning a security system are the types of threats you need to be able to detect. If you live in a wooded area where there are a lot of experienced woodsmen and hunters, you’ll have to consider how to detect people that know how to move silently and effectively and are more likely to notice things like tripwires or trail cameras. On the other hand, if you’re in an area that may primarily experience urban sheeple migrating in search of resources after a disaster, your security situation will be simplified, since most of those folks will take the path of least resistance with minimal regard for stealth. An absolute worst-case scenario would be trying to set up a security system to detect people that have military training and equipment, since they will tend to be more observant about wires, alarms, infrared light, etc. As with any system, the more complex and extensive you make it, the harder it will be to maintain and the more likely you are to get a lot of false alarms.
Once you understand the primary drivers for your security system, you should begin to develop an overall approach to how you want to implement it. The best approach is to leverage what the military refers to as ‘defense in depth’ – layers of detection capabilities at different distances from your house or property. The goal is to have multiple opportunities to detect an intruder in case they get by one of the perimeters. Remember that to stay safe in a fixed location you need to be able to detect every intruder approaching from any possible direction at any time, but an intruder only has to be lucky or good enough to get through your detection perimeter once to do some harm.Continue reading“Elements of a Security System – Part 2, by J.M.”
