How can detect sound recording devices in his room. They are the effective normal fault detectors for these too?

The normal fault detectors can find produces RF / wireless but what about the devices, such as a sound recordist on a feather, etc.?

Not only radio transmitters, but also video and / or audio recording devices are also using heterodyne technology, which requires a local oscillator. As transmitters, oscillators radiate radio frequency energy that can be collected by the fault detectors. Now here's the problem. You have so many devices in your home, such as cellular phones, cordless phones, television, stereo, CD player, DVD player, radio receiver, xbox or playstation, etc, etc, etc, an error detector that would be permanently detect these issues, too. To locate any real error, you would to disconnect and remove all power to all other electronic devices in the room. The question is, is it worth it? Why would anyone want to record the audio? One, we need a way to retrieve it. Wireless Broadcasters are a way, they just sit outside your house and let them forward. But it requires a team rather expensive, the power to issue more than a few meters, and hours and hours of sitting there, waiting for anything that might be interesting. Or you could use a recorder, but then it must be sufficiently hidden, hide the microphone as well, pointing out to somehow be able to keep it running during hours. That's quite an expense for small batteries of hours of recordings, or the requirement of large batteries for longer periods. And then someone still has to enter his house for the regular collections of recorded material. PLUS after you still have to sift through hours of recordings to find a few moments that might be interesting. A lot of work, not to mention expense, to almost no change is worthwhile. And somehow, of all people in the world, I really doubt that you are all that particularly interesting to eavesdrop.
