Posted by skrimace 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. |
Posted by MYSTERY-IS-IN-THE-AIR 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? |
Posted by AdventureDan 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. |
Posted by MYSTERY-IS-IN-THE-AIR 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!) |

Posted by Tcherno 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... |

Posted by giffomancer 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) |
