I've been thinking about things going poorly in NK and the possibility of people being displaced. Or, just TEOTWAWKI in general. So...just knowing what is going on around you may be important.
I've been looking at some solar alarms to set at a distance....but I have nothing for that yet. If someone has some experience with electronic alarms then lead me on. The specs read good...but I dunno. I prefer the "beam" type to the motion detector type. I think that will reduce false alarms and you can set it above the height small animals will set it off.
I did see the Sentry Alarm Mines ( http://alarmmine.com/ (http://alarmmine.com/) ) and ordered a few. They have a trip wire and use a 22 blank to make noise.
So my thought is electronic (bad for EMP though) to alert me someone is in the area and a Sentry Alarm to let me know they are close. Plus...a 22 cap being busted next to you will change a guy's plans quickly. They may persist with their intent...but don't you know they will be looking over their shoulder and will be less effective.
Call me paranoid....OK. I think it's good practice to know if someone is slipping up on you purposely with evil intent.

I like those .22 blank alarms. I didn't even know they had them.
-
I didn't know either. But I think they are certainly a worthwhile thing to have around.
-
I'm in for a little education also...the recent random murders in Seminole Heights in Tampa has peaked an interest in some form of electronic surveillance, but I don't really want a router tied to my computer as part of the system...

If you went with a 12 gauge perimeter alarm instead of .22 you could use blanks, flares, or pepper gas. Here's a place that makes them, and they have some that just use a 209 shotgun primer. I have no idea what the cost is for shotgun primers vs. .22 blanks but it may be worth looking into. There are several other places to get the 12 gauge trip alarms too. https://fithops.com/

Frank I like that. It looks like a good price. You can get 100 of the 22 blanks on Amazon for $8.00. I see on the manufacturer's website ( http://www.americanspecialtyammo.com/12_Gauge.html (http://www.americanspecialtyammo.com/12_Gauge.html) ) you can get 50 of the 12 gauge flash bangs for $76. Shame on you making me spend money...my wife is going to be soooo verrrrry mad at you.
I can see using a layered approach with these. The little 22's vs. the 12 gauge flash bangs. I'll have to think of it a bit, but I like the blank noisemakers in close and electronics out a bit. Most likely I'll put the 12 gauge in really close...but maybe not...gotta think about it some more.
Les, there are some like this HTZSAFE ( https://www.amazon.com/s/ref=nb_sb_noss_2?url=search-alias%3Delectronics&field-keywords=htzsafe (https://www.amazon.com/s/ref=nb_sb_noss_2?url=search-alias%3Delectronics&field-keywords=htzsafe) ) that transmit up to 1/2 mile (I'd cut that back to 1/3...just because I don't believe sales claims) that are solar charged and hookup to their own "base" unit. From a cursory look their budget base appears to accept 16 simultaneous alarms (32 sensors) whereas their best model can track 8 sensors (4 perimeters) and alert you by varied sound as to which perimeter is breached.
The HTZSAFE seems to be what a guy wants (considering user ratings) but is a little pricey. What I don't see is a really good discriminatory alert where you can track many perimeters and get both an audible and visual display. It would be great to have a dozen or so perimeters and be able to number and NAME them for a discriminatory alert.......along with the other things that this brand seems to offer.

That is excellent! You guys are giving me ideas. Imagine one of those 12 gauge flash bangs set up INDOORS when you're gone on vacation, or whatever. I could easily mount one with a trip wire very low, and across my sliding glass door. (Easiest point of entry). With the unit itself mounted to the side of a kitchen cabinet, and the other end screwed to the opposite frame of the door itself.
-
Indoors at entry point. Just think about the big pile of crap you'll have to shovel out of the way once you get home. You may want to set that outside back from the door just a bit.....
;D

I love this idea. For those of you with more machining experience would these be very hard to make?? Cheaper than the $20.00 price?
Yep I am a cheapskate. (These days you have to be)

If you had access to a lathe you could easily make them. Like most things that require machining, it wouldn't really pay to make one or two. If you had a few people who wanted to go in on them, you could make a couple dozen and it would be worth it. On a CNC lathe, once you take the time to write the program, you can make 50 as easily as you can just one.
-
Saw a driveway alarm that would notify you if someone drove up. If it was an infrared motion detector, you could place it anywhere.
I think these motion detectors that light up are handy. The light doesn’t have to be connected. For example, you can buy a 110v outlet that screws into a bulb socket. Then run an extension cord to whatever you want to go on when something is seen.

I have a mini-mill and a small metal lathe. Just not the experience to use them yet!!

My thinking is that the 12 gauge blanks or flares at the outer perimeter could scare people away, and the .22 blanks further in would let you know they're still coming. Having the loudest blanks at the longest distance and the others closer would allow you to hear both of them more easily than the other way around. But the perimeter around my yard is so close I can almost hear my neighbors fart, so I'm no expert.

I did this. Mounted two behind the mail box, hidden by a bush. One pointed at the front yard and one down the drive way. Daytime there were false alarms by squirrels and birds, but at night it was great.
I ran the 120vac line back to the house and connected it to a doorbell transformer which I then connected to my doorbells.
DING DONG. Somebody's either coming down the drive or they're TPing my front yard. Surprised so many teenagers I had a reputation at the local HS as the father who never slept.

I picked up those wireless infrared motion detectors at Norther Tool on sale. Got two sets on the same frequency. One is pointed up the driveway and one at the parking area. For cheap $10 devices they've worked well. On clear cold days they do alarm with a passing car, but primarily we use them for when we're expecting company.
Beam detectors would still pick up some birds (unless the detector has an anti-falsing delay built in) and of course larger animals, which transit our yard on a nightly basis.
There also camera based alarms that sense motion in the video and then set off an alarm. Their advantage is you can then access the video as well as the recording later.

Take Joe Biden's advice....connect the monitor to a recording that starts with the racking of a shotgun and a voice saying "ON THE GROUND!... Move and you're dead."

And if'n they run, Ol' Greasy Joe had even better advice, just shoot 'em through the door with a shotgun.

Those 2 perimeter trip alarms are the same ones I posted a link to. And now, thanks to the video, we know a 12 gauge blast to the face from a foot away would be a bad thing, no matter what kind of shell it is. And that guy in the video seems to think it was Fifth Ops with an "f" in the middle of fifth, but it's not. It's FITH OPS, as in the abbreviation for Fire In The Hole. It even says FIRE IN THE HOLE at the top of the web page.

Gentlemen,
Let us learn from the bad guys.
While working as en Emergency Services Instructor, I learned a lot. Here is how to build a tripwire or jolt activated device:
One mousetrap
Short piece of 2x4
JB Weld
1- 16 penny nail
4 - 1" tacks
1 - shotshell of your choice
TOOLS
Hammer
Hacksaw
Drill
Screwdriver bit
Drill bit (diameter to match shotshell)
INSTRUCTIONS
Tack mousetrap to 2x4;
Mark point where the small bumping on the trap bail contacts the trap surface;
With the bail held back, drill through the trap and 2x4;
Cut the point off the 16 penny nail;
Using a spent shotshell, use JB Weld to bond nail point to the trap bail like a firing pin.
This device can now be used as a trip wire alarm or weapon, or it can be mounted to activate by jolt.
Many meth cookers, and the like would mount these on their doors. When Law Enforcement came pounding, the banging on the door would set them off.

I ended up with a few units set up for 22 blanks.

That's sure cheaper than using 12 gauge blanks. I wonder how loud the most powerful Ramset blanks would be? You should be able to find from power level 2 up to level 4 (yellow), 100 per box, just about anyplace that sells tools. Regular .22 blanks are harder to find in my experience.
