 |  | Motion Detectors in sites
< on 4/3/2005 9:15 PM >
|  | | | A few friends and i had driven up to an asylum that has been abandoned since 1995, and after trudging through about 2/3mi of farmland soaked from the days rain, made it to the lot the asylum was sitting on. There were cameras on the outside of the building but we didn't worry about them. After we got inside, my friend walked out of the room and into a hallway and immediately froze. He motioned my other friend over, and slowly pointed to the end of the hallway. Sure enough there was a motion detector sitting on the wall at the end of the hallway. We decided to abandon our exploration for the night, and try to figure out more about these detectors before going back.
We found the company that installed the system (still in business). turns out these motion detectors are infrared sensing. Problem is, we are unsure if the signal is part of a local security system, or if the signal is routed to the company. After putting some thought into it we decided it was more than likely a security system based in the building, due to the risk of patients getting out of their rooms at night. Before we go back we're trying to find out how to disable or 'blind' these detectors without destroying them, just in case the signals are routed to the security company. any ideas?

| | | | Chances are if the building is really abandoned, then it has no electricity anymore, cause who wants to pay for electricity in an old, useless building? No electricity means no working sensors, or cameras. Try a light switch, if it doesn't work, I'd say your in pretty good shape.

| | | | Since no one's asked the obvious question... did you get a red light on the detector when you moved?
Also, here's an old thread about the subject. Make sure you read it all as there's a lot of misinformation in it too:

| | | | Yes, the system was active. The sensor showed a yellow color when there was nobody in front of it, and when we waved a hand, etc. the indicator turned red.

| | | | I would try setting them off, then hiding. Wait a while, if no one shows up don't worry about them.

The next question should be: Is the security system even activated?
Those motion detectors are obviously powered, and will continue firing happily all day long, but they don't make the call as to whether to set off alarms or call the cops.
IF the main computer is disabled (or removed, for that matter), there's nothing to worry about.
So, when you tripped the motion detectors, did the army show up? No? Then I think you're ok.

| | | | Thats what we figured, but a couple of our group members (read: NEVER ue with friends' friends..) thought we were going to get arrested and refused to go back in. Thanks for the info, next trip is planned for 2 weeks from now.

| | | | Another way to check is to see if there are any open windows in the area. If there is a window open, more then likely the sensor is not functional. With a window open, there would be pigeons and racoons setting off any functional detectors on a daily basis, and as a result, any open windows would end up getting sealed off to prevent false alarms.

Not really true.These houses I explored were alarmed, and the alarms were monitored (which I know from watching the security arrive after setting the motion detector off), and all of the houses had at least one open or broken window on the upper levels.

| | | | i think home motion sensors are made to only notice motion of objects of a certain mass (over 50lbs or something) to prevent people's cats and hamsters and such from setting alarms off.

Motion sensors are oblivious to weight.....

| | | | Motion detectors can be set to certain sensitivities though. I know people that have them in their house, and are set so the dog doesn't trigger them. Not sure if it's a height setting or what, but it is possible to have them allow some movement in the area. I don't know any specifics about that other than it can be done somehow.

| | | | For reference, in the future we are all going to encounter more motion detectors:
I work in the construction field. Due to high energy costs motion detectors are being incorporated into many building automation systems. (Depending on the building, an automation system is replaced every 10 years or so)
The motion detector is used to determine occupany of a room for multiple reasons. Either to turn on the lights, start exhaust fans (bathrooms) or start the rooms associated air handler to heat or cool the room. As of now I have not seen these motion detectors incorporated into security protection. But it would be relatively inexpensive to do so.
The majority of buildings I have seen this in are public. Both Schools and City halls use them extensively

One of the bathrooms at my work has a PIR-controlled air freshener...
Just walk by and voila: Morning Meadow.
So far, the lamest and most superfluous use of motion-detecting technology I've yet encountered.

Hopefully by the time that buildings that have gone up recently are abandoned some smart UE type folk will have thought of a way to get around motion detectors.
Say, how long does a motion detector battery last?

| | | | Just locate the main phone line that exits the building and cut it. No phone line, no way for the computer to call the alarm company. It will send a "trouble" signal, and they will likely send out a tech in the near future. Usually within a few days though, because phone lines do go down on their own and restore again.

Yeah, that's a great idea.
And leave your address, too, so the property owner can forward you the bill for repairing it.
