The more I think about prepping for the long term the more I realize how important early warning can be. I should point out that I have no experience whatsoever with such concepts as I never served in the military or brewed up a batch of moonshine–I just watched the last episode of Moonshiners. 🙂
Anyway, two interesting things were recently brought to my attention that may prove useful to you:
- An article on Outdoor surveillance with condenser microphones – for those with some electronics background this project is probably a breeze. The purpose is to build your own microphone to monitor your property. I like the idea but only wish it didn’t seem to require a amplifier to work… maybe there’s something else that can be done?
- A Trip Wire Alarm system – placed strategically around natural points of egress (that’s nerdy talk for places like walkways) this alarm system will not only alert you to a problem but quite possible cause the bad guy to run the other way since it fires off a .22 blank when tripped! The price might seem a little prohibitive at first glance but maybe it suits your particular situation.
If you have any experience with these products or something similar, I would enjoy learning what you know.
