The advantage of a bungee cord as a trip wire is its springiness. Think of it as a rubber band on steroids. In fact, the interior of a bungee cord is just that. Long strands of rubber encased in a flexible fabric braid. Tie a line to the ring on the firing washer, then lift the firing pin a little and slide the notched side of the washer into the grove. Not yet. We are very close to getting our product available to to the rest of the world. Due to the nature of our product, it takes more time to get approved. Also, if it’s any lower than 6 inches, every random squirrel, raccoon, possum or most any other rodent could trip your wire repeatedly. If that happens enough, you may take to ignoring the trip wire noise while assuming it’s just another passing rabbit when it’s the intruder you were so worried about in the first place.Once the rule is created and named, use "Draw Rule" to place your Tripwire line and under the "Direction drop down define in which direction, if only one, crossing is prohibited. In this example crossing from B -> A is prohibited. Wrap the one end of the wire around a tree trunk, branch, sapling or stake. Choose a color that matches best with the surroundings.

The first thing you will need to do to set up your simple tripwire is locate the area in which you hope to set up your system. This should be in an area that you feel is vulnerable, or an area through which, you are worried that an intruder might be able to access your home. You need to have two anchor points. These points could be trees, bushes, lawn light fixtures, or for a much better system, you could use hidden stakes that you drive into the ground. Next you will stretch the fishing line tautly between the two anchor points. On one side, you will need to tie the fishing line around the stake. On the other side you will twist the line around the stake, and you can tie it as well, but be sure not to cut the line, as you will be running the line up to a bell that you anchor in a tree near a window, or on the window ledge itself. Make sure the bell is loud enough that you will be able to hear it from inside your house.You don’t want to test your popper trip wire or you’ll have to retie another one. If you want to test the distance and whether or not you’ll hear it, have someone in camp or in the house listen while you pull a spare popper. If they don’t hear it, move the trip wire closer. Don’t be tempted to add multiple poppers to the same trip wire. What will most likely happen is that one popper will trip, leaving any others unexploded. This device causes a loud bang and flash when used with a 12 bore saluting blank, all necessary steps must be taken to ensure safe deployment and use. Select the drop-down menu next to Direction to choose if the IVS alarm is triggered in both directions (Both) or just one direction ("A To B" or "B To A") The resistor R1 acts as a pull-up resistor for pin 2. It helps to prevent false triggering from static electricity. This can be any value. In many cases it can be left off without causing any problems.

Laser Tripwire Alarm : 9 Steps (with Pictures) - Instructables

If it makes noise, it’ll work on a trip wire. The only challenge is figuring out how to trigger the noise. Things like sirens need power, but if you’re handy with a little wiring, you can make a trip-switch to set off the siren. So what does this little anecdote have to do with a trip wire alarm system? Honestly, more than you'd think. My brother had figured out a system (albeit using his body rather than a real wire) that has been around for over a hundred years now. He was using his body to topple me over, thus incapacitating me and making it difficult for me to get up right after I fell. All he was missing was an alarm. Although he probably didn’t want an alarm, or he would have gotten in trouble with mom. A single tripwire beam works but with the addition of a few mirrors, you can have the laser crisscrossing all over the room making it impossible for someone to avoid detection.

There are solar powered motion detectors that will illuminate an area. These are best hung high in a tree out of sight and out of reach. It’s a variation on the trip wire concept, and it’s usually used to dissuade animals. It could also deter an intruder, but if you’re using something to trip an alarm that will notify you of an intrusion, a light in the night will do little good if you don’t see it while you’re sleeping or otherwise occupied.
