 |  |  | Bypassing Shake Sensors
< on 1/8/2006 5:27 PM >
|  | | | So, me and my friends were over at Vulcan trying to find a way to bypass the miles of chain-link, barbed wire topped fence when we stumbled across what appeared to be a gate for trains to enter. I say this because a) there was train rail leading trough a gate. and b) The place was built in 1941 when trains were one of the most reliable systems of supply.
Now, we were going to jump it when we saw this funny metal box. It appeared to have a hinged face plate on the opposite side and a small chain dangling below. Now, this could be a number of things but I think it is a shake sensor. I didnt get a photo of it but it is roughly 1' by 6"
It had no wires going anywhere nor any visible antennae. However, it is a good chance it is a remote shake sensor for ADS security. I say this because the gate that it is mounted on is not barbed wire topped and very low so it is easy to close and open for trains.
Does anyone have any ideas on how to get past this without getting beaten by a rentacop? Or should I just vault it and hide hoping the secofs will think it was wind or something? Anything would be helpful. I'll try to get a pic.

|  | | | I'm not 100% on how these work. But from what I gather when the fence shakes the chain hits some magnets inside or whatever and that trips the sensor. My recommendation would be to hang a heavy weight from it and then make some supports that will attach to the fence and prop the line holding the weight a fixed distance from the fence. Thus keeping the weightline from swaying and keeping the chain tight.
Again, I don't know a lot about these sensors that's just a rough idea of how I would assume one would bypass such a device.

| | | | Shake the fence. Then go and hide somewhere legal that you can still see the fence. If someone shows up you know that it is a shake box. Wait until they leave then shake it again. Do this a few days in a row and they will get tired of responding and shut it off or just ignore it. This method of operation is similar to what car thieves do for car alarms.
Senstar Stellar is a major manufacturer of fence disturbance sensors. Images of their products and data should give an idea what to look for, and how they operate. http://www.senstarstellar.com/index.cfm

| | | | I like the second idea. The sensor is not like any of those in that link. It was huge and a weird flat alloy strung to the fence. Not anything with cables running anywhere. I think it may be out of order seeing as the original train tracks that lead inside are actually twisted together like some absurd twisty tie. Kinda reminds me of Sherman's Total War.
Thank you guys and I will post a picture as soon as I get one.
Also, the chain was hanging about 1 inch away from the link fencing.
Should I just send my guys over as quick as possible and hide (the place is huge, check the LDB link in my original post, it has to be at least a few square miles) hoping the secofs think it's just wind or animals or something?

| | | | if you want to set the shake sensor off just toss something at the fence from a distance. Like a rock, provided you're accurate enough.

| | | | Tyler Durden, i really didn't understand that device you described, but i would be willing to try it if i understood it. if you feel like re-describing it that would be much appreciated.
oh, and there's a foundry salvage place right next to the fence, but the fence is twice as tall there- however, junk laying around there could be used to make a makeshift ladder to jump over the fence.
and also, there was a gap underneath the fence around back next to The Projects that i think we could crawl through. the area was very dark and full of hiding places, too. oh, and the nearest "shake sensor" was a good ten yards away.
Anyone have any idea as to how far shaking on the fence would travel?

| | | | ok, let's see if I can describe it better:
The sensor works on the premiss that the chain shakes and hits the sides of the box. what you need to do is keep the chain from shaking in order to do that you have to first make the chain taught. So attach a weight to some fishing line and a some kind of hook and hang that on the chain. That will pull the chain tight.
Now you need to keep the weight from moving too much, so using some stiff wire, like piano wire make spacers that will push the line out from the fence. By doing this the weight holds the chain tight and the chain can't move.

| | | | oh, i see, thanks much.
couldn't you also use a strong magnet on the underside of the box to keep the chain pulled taught downward, if the chain was enclosed inside the box?

| | | | Personally I'd get a better look and find out exactly what it is.. you could be holding up good exploration time by looking at some box/chain that got stuck on a fence when some wacky teen bastids tried to throw it over.. I'd say if it doesn't make sence and things don't add up with it, just give'er a mighty poke with a stick then find cover for a while.. if you have multiple people have them look at the major entrances as well to see if security of types show up..
And for those of you that want any further understanding of how these work go rent 'The Rock' the thing they set off in the shower room is a small one but it works on the same idea (i'm sure there are different types, but in the end I would think they all use the same 'basic' ideas)
Also look along the wall to see if there are more of them.. walk the fence and check.. If theres only one just hop somewhere else then come around from inside to get a better look..

| | | | If it is some kinda sensor and there are no wires than chances are the batteries are dead... For it to work its gotta send out a signal. Simply be careful and wrap the box with a material that blocks radio waves or make a jammer

from my understanding (and correct me if I am wrong) the place is active..
Depending how paranoid they are they could have some beatoff rentacop walk the grounds at some point and knock the fence to make sure everything is working (at least that would make sence to me, which means I doubt they would..)
Not sure what this place does, but is asking for a tour for a 'school project' an option? Yer pretty young right?

| | | | My gut tells me that if it was a shake sensor, it wouldn't have the chain hanging out.. it would be entirely self-sustained triggering mechanism and the only external bit would be the power source wire.

About Stealth-Flex
The Stealth-Flex Fence Protection System consists of a sensitive cable, using state of the art microphonic technology to provide detection of intruders' attempts to climb or cut the fence. The cable is resistant to false alarms from environmental influences and unaffected by heat, UV light and moisture.
Stealth-Flex microphonic cable is attached to the fence, using simple cable ties. The analyzer is available in a NEMA standard environmental housing for attachment directly to a fence post or in a sturdy metal can for indoor installation. On detecting an alarm condition, the analyzer activates a Form C relay which can be connected to any alarm panel, cellular transmitter or other device.
The analyzer's sophisticated electronics allow simple but precise adjustment of sensitivity to meet the requirements of any installation. The Stealth-Flex system is ideal for high security applications, while its low cost and simplicity of installation allow its use in a variety of locations not previously considered for this kind of protection.
Simple to Install
The Stealth-Flex is available as a complete kit, protecting 500 feet (SF-500),1000 feet (SF-1000) or 2000 feet (SF-2000). The kit includes cable, analyzer(s) and end-of-line termination kit. The cable is easily fixed to the fence, using cable ties, permitting a much faster installation than shock sensor based systems. Sensitivity and pulse count adjustment is facilitated by a bar display.
High Security
Stealth-Flex detects attempts to climb, cut or otherwise damage the fence. Cutting the cable itself will generate a tamper or intruder alarm.
Tried and Tested
Stealth-Flex microphonic cable protects many high security locations, both government and commercial around the world.

I've been reading this and just waiting for someone to bring this up. If you don't think wind can catch a chain link fence you've never seen one after a hurricane. I’ve seen one that used a wire attached to a chain link fence but never a bell type object with a swinging pendulum on an outdoor fence.
It would cause more swing.

2 for 2. To many 'you should' ideas put forth by people who have never actually tried them. You want to test your theories than go buy pieces of an alarm system and play around with them at home. Don't tell someone it'll work and you've never tried it.

| | | | Hahaha you suck TDK. Anyways, I'm reasonably certain now that it is not infact a (working) shake sensor. It looks alot like that thing Spooky dan posted but with no running cables anywhere.
I'm thinking, we'll take our chances and RLH then hide to see if it is really a shake sensor. I guess I'll leave the rest of my guys outside with radios to give me a heads up if some secofs arrive.
