Motion detectors

I found this video that mythbusters did. The results are pretty interesting. You can get past a motion sensor by holding up a blanket to shield your body from being detected. I'm not sure which type of sensor they were using, but it seems legit. Do any of you guys know if this method works for all motion sensors or jus a specific type, and if it is case sensitive, then what conditions would it work under? Here's the link: http://youtu.be/x8vmd3DkzDg (sorry I don't know how to embed the video)

IMHO, bypassing motion detectors isn't really practical in a UE context. There are plenty of ways to bypass motion detectors, but you'd have to know exactly which motion detector you're trying to bypass to employ the right method. Some can be bypassed with a sheet of styrofoam or some other thermal insulator, some with a flash of UV light, some simply by walking very slowly, and others can't be bypassed at all. All depends on the specific device.

Sometimes you'll find a security firm that are really bad at their jobs and set up power supplies and comm links outside the perimeter. This is probably your best bet if you're desperate.

Oh, thanks for all of that information, I didn't know that. I guess it would be ridiculous to lug around all of the extra supplies you would need to bypass various motion detectors.

As for the power supplies and comm links, is there usually a specific area that they would be located, and if you know, how often would you say this happens?

Well around here, the only thing really in use is PIR (passive infrared) detectors. These measure infrared changes (in practicality, HEAT) between beams of passive rays emitted from the device. These are extremely easy to spot, and don't usually have a good range. A thermal emergency blanket does the trick if you spot them before they spot you. I used this with much success for our senior Prank in highschool. But i had the advantage of going to school there during the day and being able to write down the location of each one on the fire plan map i had.

The problem is they tend to be above door jams facing out. so unsuspecting individuals won't know they passed one till they are coming back. This is why i almost never walk through a doorway before first peeking up at the door jam above me on the opposite side.

But even so last week i did just that and walked right through one and then thought "I should check...." to my dismay i turned around to see a flashing red light indicating i had tripped the alarm. Luckily i recognized this and GTFO of dodge. I watched the place from the block over and sure enough here came the porker squad.

I couldn't tell ya. To speculate, I'd say probably not often these days what with wifi and more efficient batteries; the sensors probably all have their own rather than running wire to a central pack. The GSM link could be anywhere. I've seen a few photos in the forums of 'em people have found, one of which was just chillin' on the floor in an empty room.

Personally, I wouldn't fuck with it. I'm no lawyer, but I'd imagine bypassing and/or disabling electronic anti-intrusion measures stretches a bit beyond trespassing in the eyes of the law.

That's awesome thanks for the tip, but where can I get a thermal emergency blanket?

If you don't mind me asking, what did you do for your senior prank?

Do all of the alarms flash red when you trip the alarm? (Sorry for all the questions, this info is just too good!)

Should be able to get an emergency blanket at any Walmart or store that sells camping supplies. It looks like a block of tinfoil. And as far as I know they do flash red. It's how the people installing it know it's working properly without having it go off every time they test it.

However, like i said, I knew where every detector was before hand, so it was a bit different from an urban exploring setting. Also walking around with a tinfoil blanket in front of you, not being able to poke your head out to see is a bit impractical.

And for our senior prank we were going to do all sorts of stuff... like fill the principles office cubicle to the roof with beach balls, and hang blown up condoms from the cafeteria ceiling... I did a test run to see if i could get into the building at night and get past all the security and it worked. Unfortunately all my buds who were going to do it with me, chickened out and bailed so no prank was actually executed

Also that video of the mythbusters uses Sonar detectors. Hence the sheet. It absorbs the sound waves. However this probably won't work with infrared as the sheet won't hide your heat signature well enough. That's why you use a thermal blanket. I have yet to ever see a sonic motion detector in use.

Thanks for the tips!

Tried some of the Mythbusters techniques at home, but they don't work well.
Here in Europe, more and more locations are getting alarmed.. need to do some homework

Hate that blinking red light! That being said, I have yet to get caught by one of these. I have set a few off but either they were old or no one was paying attention. I sat around from a distance but the cops never came any of the 3 times..

I've seen loads of infrared detector in my explorations... Usually smashed on the floor, which is a good indication that the building isnt worth maintaining the alarm system anymore lol).

I also triggered some too, there is a thin line between that is sometime difficult to see, between abandonned and long long been unocupided.

That said, i had the chance to visit an abandonned provincial police station once, found many motion sensor on the floor. I picked one and checked in it... They were the microwave ones (police have budgets to spend lol) and i found that there were jumpers in it, to set the sensitivity, angles, a tampering remote detection but also... one to enable or disable the blinking light.

I used not to worry too much about motion detector that dont blink...

I've never encountered microwave alarms...sounds scary! Did you trigger the alarm immediately?
How do you tell if the alarm has actually been triggered?

The police station was long abandonned... the motion sensor was on the floor, no longer attached to its wires, so it didnt triggered LOL

But still intact, on the wall, in an active place where they actually want to catch intruders, you probably cant know if it trigger or not.

If a motion detector ring the alarm, "they" want you to go away, fast. If it stay silent, then it's broken, unconnected, or they are silently comming to catch you.

Common wisdom would recommand not to go where one suspect such trap ;-P

I wouldn't worry about motion detectors. They're not worth your time to bypass. (Although most PIR sensors can be bypassed with Tupperware...) Either avoid them or just ignore them.

If you do accidentally trigger them, consider the possibility that you are safer to stay inside the building, especially if there's a siren/sounder going off. Security or police will be looking for the guy running down the street, and will likely not notice the guy who decided that now would be a great time to go explore the basement or roof. Just try to avoid the area between the front door and the alarm panel unless you can run fast.

I have to discourage tampering with motion detectors, or alarm systems in general in a UE context. But if you're playing with your own equipment on your own property for educational purposes, I would say that tampering is best done at either the panel or the sounder/dialer. I might also tell you that alarm wires can be easily tampered with in such a way to render all sensors in that zone inoperable, and in some cases even power off the panel.

Have used the blanket technique with some others as already stated. Close your way in set off the alarm head for cover in a roof space or basement. IF you hit a redcare alarm(UK), these are directly linked to a police station. Who dispatch the nearest cars to the location we tested a system of this type. Police where on site in

1st time - 8 mins
2nd time - 6 mins
3rd time 4 -6 mins and in silence no lights or lights on foot and quite

There is another system we term the Daleks here who irritate the hell out of locals. The stations are bolted to the outside of the building and are wireless. the detect heat and motion fire the information back to the main robot and that contacts the security company. Pain in the ass broad Irish accent telling you police are on the way !!. you have to take a guess at the times limit to these.

every security system has week points !

I have few questions, Theres a locations i found thats rigged with motion alarms but i have no idea where they are, i figured there two sets one that goes off to scare intruders and the second is to alert the police, ill attach videos to what im talking about

even though the video duration is 2 mins from memory i was in there for at leat 10min and as you can see from the first video alarm went off after i triggered the water fountain

Part1
https://www.youtub...atch?v=roxJbUV9ghw

in the second video at same location i triggered multiple alarms as i was in this location for no more them 2 and a half hours, at 3:29 i set off the first alarm siren but continue to push forward and then at 5:18 setting off another low frequency alarm which i suspect alerted law enforcement or the caretaker in charge of the location.


part2
https://www.youtub...atch?v=oPlifG2NNQU

now in the basement morgue at 40:40 in the second video the alarm noise is VERY loud but on the right side wall there seems to be a electrical box i assume with switches, would that be where the on/ off switch fr the alarm is at?
