There are devices made to detect the presence of semiconductors, and these
have been out for ages.
And now with the war on terror going on, you would not believe what kind of

Minor modifications of some of these units would not be very difficult to
detect a mere MP3 in someones pocket.
But then these would not be cheap either, if you can even get one.


Detecting electronics devices in general, is it useful? We
dont know the exact scenario, what the result would be of a
positive detection but as above, cell phones and pagers
would tend to be caught and are going to be far more common
and innocuous than a recording device, though in the former
case, the phone may have recording capability too.

Yes, which is one of the reasons why detection of these
won't help, unless ALL such devices are banned which is
unlikely... but again, we dont have the specific scenario to
consider.

I would believe you are taking a random unfounded
presumption that someone "could" be possible without
supporting evidence, nor consideration of what would be
necessary to distinguish this particular device.

Minor modifications of some of these units would not be very difficult to
detect a mere MP3 in someones pocket.

Unfounded speculation. "Maybe" it's easy enough to detect
the device when turned off. "Probably" if you were close
enough to the device you could even detect that it's turned
on. That's a far cry from identification as an MP3 player,
let alone one that is recording, vs another mode of
operation (like playback, wouldn't it be highly possible
someone who has an MP3 player, would have it to play MP3?)

But then these would not be cheap either, if you can even get one.

Establish that such a device exists at all, that can detect
an MP3 player recording, specifically discriminate it from
other devices. Nevermind if we can buy it or how much it
costs, establish that it can be done at all as so far you
have not.

Depends on the OP, his office can ban those items in the work place.
The point remains they are detectable.

Nope.

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. Rather, it is
your burden to be specific with the claim that it's possible
by showing even one reproducible example.

We have no reason to believe a scenario like the OP has (too
vaguely) posed, would allow identification of a device as an
MP3 player that is recording. 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.

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

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.

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.

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