Will it open magnetic door locks in, say, office buildings? What about a skillfully placed regular magnet?
Can of compressed air can often set-off the motion detector on the other side of the door that lets people out. That's according to the pen-test people at defcon.
really? does there HAVE to be dust or something? I mean what is MOTION detection anyway? Sight? Light? based? movement of AIR? motion, but WHAT is detected?
Some of them are temperature change motion. I think the myth busters used a glass sheet to defeat one.
I imagine the real world applications are varied.
Does it require a LARGE power consumption from some source?
I don't know.
Depends on the lock.
RFID cards/ID sends out a signal and requires a specific response.
The reader could be hardened to withstand some low level EMP attack, and a standard magnet would do very little - unless you were to oscillate it at a very high frequency to mimic an EMP.
