How detect if MP3 player is recording in your room? [OT]

Suppose someone visited your office or home and tried to make a voice recording using a hidden recorder. If they used a older-style dictation machine based on tape then you could detect the electromagnetic transmissions from the dictation machine when it was recording. But how would you detect if someone was secretly recording with an MP3 player that recorded to flash memory? Is there some transmission which could be detected? Perhaps some low power ultra high frequency from chip refresh cycles? WEll, you could just stick an antenna up next to the player and see. This is what a sandisk looks like playing mp3s. Can you tell which trace is of the sandisk? Reading the title is cheating... http://nm7u.tripod.com/homepage/nothin.jpg http://nm7u.tripod.com/homepage/sandisk.jpg mike |

How detect if MP3 player is recording in your room? [OT]
Can you also wrap sandisk in copper foil and do the same exercise?

I can clarify whatever you are unsure about if it helps. The specific scenario should have been, needed to be mentioned at the opening of the thread. Because it wasn't, the time spent on the thread wasn't very productive and many have lost interest. Actually it is only for those who need extra info that I can provide clarification. Most others here don't seem to have that need. |

Most others here don't seem to have that need. There are devices you can use that will detect devices that may be used to record your conversations. You will not be able to identify that it is an mp3 player until after a physical search. So by using this device that basically will tell you that the person has some form of electronic device on them, be it a cell phone or mp3 player. You can then use the knowledge of knowing they have this device to direct what you say or do not say You may want to spend a few bucks and talk with a local private investigator about your concerns. He may also know where to obtain these type of scanners. |

Even now you are withholding this info so we have to assume you don't really care. If for some reason you were overly paranoid about something, you would merely leave out any specifics that were identifying. |

If for some reason you were overly paranoid about something, you would merely leave out any specifics that were identifying. You've just been espionaged! (What a wonderful word!) Anybody who's been following this thread, and understands the general field, now has a pretty good idea of the state-of-the-art in surreptitiously recording spy-vs-spy. The initial conditions either weren't considered and were accidental, or were tailored exactly to get this state-of-the-art summary. The question is, WHO have you been espionaged by? Industrial spies? Terrorist spies? Government spies? Other categories of spies? An author writing a techno thriller? All of the above. Who would want to know that kind of information? (Just what seems to me an obvious paranoid possibility. It would be a lot more fun than asking on the writer's help boards.) Have a happy Halloween! |
