Deveillance also claims that the Specter can find nearby microphones through radio frequency (RF) detection, but critics say that finding a microphone via RF emissions is only effective if the sensor is right next to it.
“If you could detect and detect components via RF, as Specter claims, it would literally be a game-changer in technology,” Jordan wrote in a text to WIRED after building a device to test detecting RF signatures in microphones. “You could do radio astronomy in Manhattan.”
Deveillance is also looking at ways to integrate nonlinear connection detection (NLJD), a very high-frequency radio signal used by security professionals to find hidden microphones and bugs. NLJD detectors are expensive and are mainly used in professional contexts such as military operations.
Even if a device could detect the exact location of a microphone, objects in a room can change how frequencies propagate and interact. The emitted frequencies could also pose a problem. There is none…
