alarm system that doesnt let theives touch your car it will scare them off before they get close If you have trouble around your home with car thieves try this, this is what I have set up. I got a car battery, and a battery box to suit, fishing line 100lb you could go with a lighter weight, and a set of tri tone air horns. and a toggle switch ( get a plastic one ) should hear airhorns at 2am in the morning you'll also need 2 washers, and a small screw. make sure the washers slip over the top of the toggle switch. i'll run that list of things to get again Battery Battery box to suit toggle switch, get a plastic one with the flat toggle bit on it air horns fishing line 2 metal washers make sure they will fit over the toggle switch small screw ------- <- about as long as those dashes and some electrical wire and tape 1 four inch nail first thing take your toggle switch and at about 1/2 - 1 cm from the top drill a small hole through the switch for the small screw to screw into. now fit the switch to the top of the battery box. and screw the small screw in the hole you drilled only screw it in till the tip starts going through the switch put battery in box run some wire from positive terminal to one side of the switch ( put a fuse in there if you wish) then run a wire from the other terminal on the switch to the positive side of the air horns have it long enough to put the airhorns some where ( I had the air pump and horns screwed to my wall ) then run a wire from the negative side of air horns to battery ( make sure switch is in off position ) you may deafen yourself now for fishing line ( this is going to be a trip wire for the horns ) find a suitable spot for the fishing line to be postioned around the vehicle try and have it about a meter or so away from the car I have the fishing line tied to a fence, and it ran behind the car around a pole up the driveway beside the car around another pole and to the back door of the house where the battery box is, you can practically do endless running of the fishing line, but try to keep it simple, ( I had 3 lots of fishing line running off mine ) make sure you have the end of the fishing line thats not going to the switch on something solid, if you have to use a tree position it on a trunk not a branch, the wind will blow a branch and set your alarm off when you have found some where to run the fishing line tie one of the washers to the line then drive a nail into the position ( you may have to find other means of doing this)(you may have a metal fence ) etc therefor your on your own you'll work it out WARNING if you have dogs or cats around, make sure they can walk under the fishing line without setting it off. run your fishing line out and cut it when you reach your battery box ( have the battery box away from a wall about a foot or so, this allows adjustment for the fishing line and switch position and will save you trying to get the exact length of the fishing line) then tie the other washer to the end of the fishing line that will go on the switch you may want to test it with the airhorns unplugged or just have the air pump hooked up ( take the hose off the pump that runs to the airhorns) run your fishing line out and test away. mine was set off around 2am one morning, I heard people talking about hearing an alarm go off at 2am and that was 2 km away from my house the sound of air horns travels well in the silence of the night A carport would be the IDEAL place to use this setup just run the fishing line around the poles of the carport. anyway thats the basics of what I have setup, feel free to add bits to my info may take a bit to get all the fine tuning done but you'll get there. it workes very effectively for me as mine has been set off a few times now no it wasnt dogs or cats etc, cause the front gate was left swinging in the wind ( just wish I could get up quick enough to see the little bastards runnin out the gate, bet it scare **** outta them LOL. it seemed so effective my uncle asked me to set one up in his SHOP aound the cash registers I hope this works for you all oh yeah just a reminder try and remember where you run your fishing line, I have stumbled out of bed on many mornings and forget about it and set the horns off, it wakes you up in a hurry ok ok I am going to post this now have fun with it all, and I hope it saves you the broken quarter windows or busted locks on your cars ( as the theives can't get to you car )
how bout some picts? of course, not of your trip wires or where u put them, but maybe some picts of the set up? like how to conenct it all? pictures would really help! but great idea, i might have to try it myself....cant trust anything these days :cry:
sounds like a well thought out setup. But to go to those measures its just sad that people are willing to trepass on your property, and attempt to steal your pride and joy. very sad indeed :ranting:
it's unfortunate the lenghts you have to go to to protect your pride and joy these days. it's unfortunate that the more poeple that use this idea the more common the knowledge will be and therefor the little bastards will start looking for it. great idea though suggest maybe putting 240 volts on the gate latch at night, that'll deal to em good and proper.:thumbsup:
wow. that seems kinda complicated. I’d be inclined to lock any animals you have up and install a sensor light and in addition to the sensor light hook up a 12volt transformer to run your air horn and control when the alarm system is set with a master switch inside. or…….. get some really big dogs that eat people
You know in africa u can install flamethrowers on the side fo your ride? yes its true car jacking is that bad over there, takes a push of a button and toasty! Theres a video around somewhere.. Just a thought anyway, if they allowed stuff like that over here .. id say car theives would be no more.
Simple... park your car in your garage at night... If you dont have one, build or buy one... If you rent... move to a house with one.
Can't see this as anything more than a disturbance to your neigboures/suburb (some poor piss head needs to do a piss behind a tree and bang, air horns go off). There are restrictions on the decible levels on alarms. Sounds like your pretty paranoid. Have you got insurance, i have this so that my neighbours and myself can sleep easly. Sound like you need an alert dog, as they will bark if someone is around, and don't require reseting at 3am in the morning. How will you charge your battery? Do you think you should use a relay, as its only a matter of time before the switch contacts get welded together, and you can't switch it off in a hurry.
long time offline. anyways this idea was well worth it because yes I was renting. Don't like dogs, it was a much cheaper and easier option than building a carport/garage or moving to a house with one. the idea of the trip wires is to prevent damage to locks and glass on the vehicle, yes I do have car insurance, putting the wires up is much less hassle than waiting for the insurance company to pay up, and is again a much cheaper option than having to pay excess on insurance, and having a higher premium next year. as for the pics requested I have now moved house and haven't yet set it back up. I could possibly draw a diagram and add that. as for charging the battery I have and $15 battery charger thats works fine, on average though I get approx 3 months battery life b4 charging is required. Switching off was relatively easy, as I ran a separate switch into the laundry of the house which was easily accessed. if some poor pissed bastard wants to piss in my yard I hope it scares hell out of him and he pisses down his leg. As for the contacts becoming welded together, I tested the compressor, and no welding occured after it had been running for 10 minutes. although after ten minutes battery was gettin slightly sluggish, oh well got the charger out and charged it. the more poeple that use this idea the more common the knowledge will be and therefor the little bastards will start looking for it. well I think in everyones application if it became common knowlege, the setup would be different. anyways it has worked for me in the past, I stated respones above to those who replied. I do believe everyone has right to their opinions, so I thank you all for your replies
Well mate, you did put in a lot of thought, you planned it, put in the work, and its a solution that works for you. Does seem like a lot of effort, certainly wouldnt work for anyone, but at least it shows you are capable of pulling off a working system. I was going to say, just get it insured and if your still wanting to keep it, put in a kill switch. The only problem there being, they can just break all sorts of parts on your car, and it wouldnt be worth going through insurance. Police wouldnt be too concerned. You have just about no chance of covering the damage financially without digging into your own wallet.
Did you move to a place with a garage? You still have not addresed the issue of being a pain in the ass to the neighbourhood. The switch will be fine if the compressor is running for ten minutes, contact welding will occur on a cold start up when the current will be at it's highest. Well, maybe your right about the piss head on your property, i should have said a stray cat or dog could have triggered it off.
.... As long as its not goin off everynight i'd be glad for my neighbour to hav one set up. Lets the whole street,block,suburb know theres a prowler around the area.
Sounds like a cool idea but I'm not quite sure how it would work in practice, surely you need to have one of the trip wires going across the width of the driveway as that is the most obvious way that someone is going to approach your car, but then it needs to be high enough that you can drive under it when you get home, but then it's at chest to neck height and would be a major annoyance any time you wanted to go get something out of your car, or is the system meant to be set up and dismantled every day
Are there any legal issues with having a system like this that could potentially cause injury to an unsuspecting fellon? I would guess if one were to injure themselves they could then attempt to get $ from you for causing them an injury.
