There are devices that can detect when electronic devices are being used. There are devices that can be made that can detect almost any known material If said mp3 player is made of that material it can be detected. Which is not entirely applicable, Sure it is Nope, not without the scenario. since plenty of non-recorders are made of circuit boards, ICs & other discretes, and some plastic. Cell phone and pager are two quite common ones. Yep, and all are detectable, and all have signatures. You have not established that the signature (difference) of such a device can be discriminated from a different device. The scenario has not been defined enough to know if the device will be turned on within the distance of the scanner/other detection device. Random ideas that "something" similar is possible is not same as application in a specific scenario. Detecting electronics devices in general, is it useful? Depends on who you ask The OP is not the only one who wants to ensure no one is able to record conversations, or hear conversations they should not be hearing. We dont know the exact scenario, He gave the scenario. No. A hint, but not a full scenario might include something like what happens if "something" is detected, both the full purpose and result. 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. True enough, but the technology is there to do what is being requested. Now if the OP can afford it, or even obtain it is a different issue. You have not established this. That some fields can be detected, that it can be known if something is running, is not same thing as knowing a digital recorder is running. This difference is quite important in many scenarios because OTHER types of devices are far more common in modern society than digital recorders. |
