Motion detector?

[AfterRain]

I was looking at this place , and there is a motion detector in the corner of this place to the left , but about 10 to the left is a wall , pane of glass, and shit, im just goin' to draw it out..

Well i want to know is will the pulse sent from the bottom left sensor, bounce off the window? I think it does Because that little room on the bottom right is a 24hr ATM, in order to get into that room you must insert your atm to a reader , and then the doors will open, they have them electromagnetic locks , and from the outside its locked, but when your done with the atm it unlocks, also explained in NBK's post. there are 2 sets of doors , first set it for the 24hr atm , then the next set it for the store during work hours. Well i want to know if i got a pane of glass my height and width, could i hold that up wit a suction cup and it walked right through the area were the pulse's are being sent? ALRIGHT THANKS

no you couldnt

[Mick]

are you fucking kidding?
a 615kb BMP image.

would a mod please remove the image url.

Then how does the alarm not trip ? Is it that section of the alarm shut down untill they leave? If not, There is nothing from stoping the sensor to pulse into that room area, there is nothing blocking it at all, when iam in this room , i can see the sensor with nothing blocking it, and is it possible to shut down just that section, or would you need to bring down the whole alarm, for say a set time, then reactivate it?

about the image, i'll make it smaller now

alarms are in sections, you deactivate individual sections depending on where you want to go.
the sensor is probably controlled by the door swipe.

either that or the sensors FOV doesn't cover the ATM room.
(just cause you can see it doesn't mean it can see you.)

[pyromaniac_guy]

there are 1001 reasons why your plan might not work, a few, in no particular order...

(alot of this depend on what type of motion detector your talking about, there are active ir, passive ir, microwave, and ultrasonic to name a few)

-the motion detector may be set to register motion in a range not exceeding the placment of the window
-there may be a mecanism that detects the door has been opened, and shuts off that motion detector until lthe door is opened again for the person to leave
-the motion detector may be on a timer that shuts it down after each entry into the atm area
-the motion detector may be a fake purposly put into plain view
-the glass may inhibit the sensing beam from the motion detector in an active sensor (not likely as it's near ir) HOWEVER the glass window isnt moving, now is it!!!!!!!? if you held up a piece of glass to sheild your movments, would the motion detector not detect the motion of the glass you held? you might as well hide behind a peice of cardboard box...
-passive detectors rely on a moving change of temperture from ambient. the human body is normally alot higher than ambient temperture, but if you were to take a large piece of glass, unless it happened to have the exact same temp as the room you were in, it's much larger physics size would make up for the fact that it only had a small teperture differential from the room....

Alright, thanks man, Has anyone been to the Theif Forum... And if so, what needs to be added, As you'll see i have B&E,Auto Theft,Id Theft, and Misc section which will be little petty shit.. ALRIGHT THANKS

pyromaniac_guy, about what you said, would'nt it just reflect the pulse away and no to the sensor?
altho the glass is not moving, but people in that room would be, But im guessing it just shuts down either timer or when you enter

learn to spell

[kingspaz]

auzquad, learn to spell correctly and use punctuation such as full stops. your native language is english, as you are from australia, so you have no excuse for poor english.

Would putting a piece of aluminum tape on the sensor (during business hours) work?

[stanfield]

yeah, put an opaque plastic piece during the business hour and the sensor won't work anymore. Don't be caught...

[nbk2000]

It'd be quickly noticed that the door announcer wasn't working. And be quickly removed.

Only if you did it IMMEDIATELY prior to sneaking in would it be useful.

[green beret]

If you have a can of spray-on clear laquer you can use that as a substitute for the tape, just spray a few layers over the sensor.

Do you mean PIR's?

DREAM- In a certain high school, there appears motion detectors resembling this one in every room <a href="http://www.smarthome.com/7481.html" target="_blank">http://www.smarthome.com/7481.html</a>
Now in the room I'm interested in, there is one attached to the wall with a wire leading up and into the ceiling.

My first thought was to just go into the room a couple days in advance of entering through a window and snip the wire right where it comes out of the detector, but I figured this would signal faculty that it was disabled. Is this so, or it it dependant on the security system brand?
I do have access to this room, so I would be able sneak in and paint the lens gloss white with a small model paint brush. I'm not sure if a layer of paint would block IR radiation. This appears to be a cheap model because no small light or LED comes on when you walk past it, which would help to see if it detects after I paint it.

What could I do to disable this motion detector without alerting administration? Once the detector is out of the equation, I would have all night to "stock up." The room is the second story up, there is all kinds of shit laying around including a ladder that would make it simple to get to the window, once through the window (with duffel bags), I'm in heaven, and I can pick the lock to a certain kind of storage closet. The window is not visable to surrounding houses either. :)
