A Non-Linear Junction Detector (NLJD), such as the LORNET model, is a specialized electronic counter-surveillance device used to detect hidden electronic components, whether powered on or off. It works by transmitting a high-frequency radio signal; any semiconductor (found in listening devices, cameras, cell phones, or explosive circuitry) re-radiates harmonic frequencies, which the NLJD picks up. This makes it an essential tool for Technical Surveillance Counter-Measures (TSCM) sweeps to locate covert bugs, and by EOD teams to find electronic fuzing in Improvised Explosive Devices (IEDs), ensuring the security of sensitive facilities and personnel.

  • Detects hidden electronic devices by their semiconductor “signature,” even when off.

  • Critical for Technical Surveillance Counter-Measures (TSCM) and bug detection.

  • Used by EOD teams to locate electronic components in IEDs and booby traps.

  • The LORNET NLJD is a specific, professional-grade model known for its sensitivity.

  • A non-intrusive way to sweep rooms, vehicles, and objects for clandestine electronics.

  • A cornerstone tool for physical security and counter-terrorism operations.
