You'd be surprised where people can hide things:

Sure, but I don't think the MP3 recorder would work very well in there, so
the point is moot.

Don't see why not - it's a solid state device. Disguise a little mic
as a labial piercing stud, run the wire up the folds, and it's very
unlikely anyone would inspect it closely enough to figure it out, even
if it were visible behind the bush.

Having the recorder embedded would help reduce what little detectable
EMI a low power device like that give off, and the mic wire would only
carry audio freqs, which don't transmit very far at those power
levels.

You just have to think outside the box a bit.

You mean the point you never made.

Electronic devices made the point.
They exist, you may not be aware of them, but that is your issue.

It's not my issue to claim detection of different devices
proves detection of an MP3 player recording.

I never said it can detect an MP3 player recording.
I said it can detect an MP3 player, or pretty much anything electronic.


We have no reason to believe a scenario like the OP has (too
vaguely) posed,

Actually what he needs is a device to scan for electronic devices, and they
exist already. How the OP handles the knowledge of such sweeps depends on
him.
He can either ask for the people to remove all electronic devices, or he can
watch what he says.


would allow identification of a device as an
MP3 player that is recording.

Not recording, but its existence. Its existence can be determined, and it
does not have to be on, as there are devices that look for semiconductor
junctions(pretty much any electronic device that has at least a diode in
it).

Identifying the existence of
"some" kind of device, then a search uncovering this device
and a physical examination to determine that it is recording
(looking at the screen or lights) is another matter.

True, but the OP would know there is some kind of elctronic device on the
person that may be capable of recording. How the OP uses that info is up to
him.

Yeah, good point. I never considered an external mic. I guess the nude
office will have to ban labial studs. They should also ban scrotal studs in
the interest of fairness.

What "it"?

Devices are being discriminated by their signature.
Various sensors are doing this.

Do you know how many MP3 players are out there?

Yeah, so what. There are devices that can detect semiconducter junctions.
MP3 players have semiconductor junctions, hence they can be detected.



No, you can detect semiconductor junctions then, but not the
identity, nor function, of what larger device you have
detected as having semiconductors.



Now how about the phones that can record?

They also have semiconductor junctions, hence they can also be detected.

Again, we are not merely trying to detect some arbitrary
substance, it has to be a complete detection that
discriminates a recording MP3 player. If all we cared about
was that "something" was there, we have no need to consider
semiconductor presence at all.


A theory about
what might be possible someday, is not same thing as what IS
being done today.

Semiconductor junctions can be detected today.

Again, it's pointless.




You seem to be vaguely claiming it's possible without really
considering EXACTLY what is necessary.

Hogwash.
You seem not to understand what can be done with electronics.

You seem unable to describe any way to discriminate the very
thing this thread is about.


There are some devices that use the priciples of a MRI and shrink it down to
a hand held sized device to scan for explosives.

Ok, but again, it doesn't tell us the purpose of common
items like plastic, or semiconductors. Explosives aren't
going to be used in practically everything that plugs into a
wall or takes a battery.

Since the compounds in
explosives give off a unique signature after being exposed to a strong
magnetic field, that signature is then stored in memory.

Maybe some, but not all will give off a magnetic field. It
doesn't matter though, there is nothing in particular in an
MP3 player that would discriminate it from a cell phone. Is
it not obvious to you that common items people are allowed
to have, can't be false detected? Perhaps whoever is
subject to this search is first told to empty all pockets of
such things, but as already written, we'd need to know such
a scenario to delve into this kinds of tangents.

Now your sensor
emits a magnetic field, and the reciever looks for the signature of the
explosives.

Great, if a recording MP3 player is made out of explosives.

You seem to have trouble distinguishing between random
non-applicable information and the crucial details necessary
to discriminate a recording MP3 player.


So it is only a matter of expanding your signature library, and your
receiver can be programmed to look for pretty much anything.

Nope, and you might as well stop pretending you know about
this stuff because you have pretty well given yourself away.
There is no one signature an MP3 player would have, it's not
made of one unique material and there are myriad different
players with different % of several materials, but
practically all of them are commonplace, unlike explosives.


This is only one of many new tools that are out.
The semiconductor junction detector has been out for around 30 years.

Show one recording MP3 player having been detected like
this, anyone who claims they have a specific device that
does it and can explain how- because it sure as heck isn't
using a signature like with explosives.

The thread is about detecting an MP3 player. Show us it can
be done, regardless of whether recording or not. It would
have to be discriminated from other devices, and DEPENDING
ON SCENARIO, from a fair distance and continuously, else the
person carrying it just turns it on when needed.

I have never claimed "electronic devices" can't be detected.
It's not enough, electronic devices are everywhere! It'll
have to discriminate, unless you're in a 3rd world country
where they can just go ahead and shoot anyone they suspect-
so there was no need for a scanner at all.

I can clarify whatever you are unsure about if it helps.

No problems.

Seriously though. There's very little in world that's so
important. I've worked with people that would *record* meetings
thinking they were of vital importance when in actual truth, no one
could care less.

I guess it would just cause people to be more careful about what
they say. I'm unable to view those videos you've supplied as this
is a development machine without any clutter on it.

eBay could be a good place to buy such things though. All sorts of
stuff comes out of the AsiaPac.


This is to document something quite serious.

Are you the trying to be the documenter, or trying to avoid being
the documentee? Or both?


I don't want to be recorded.

But I would like to know if I can be detected if I do attempt to make a
recording.
