ORION™ 2.4 HX 


Orion 2.4HX NLJD.JPG

Locate Eavesdropping Devices

The ORION 2.4 HX Non-Linear Junction Detector (NLJD) detects electronic semi-conductor components in walls, floors, ceilings, fixtures, furniture, containers, or other surfaces. The ORION 2.4 HX NLJD is made to detect and locate hidden cameras, microphones, and other electronic devices regardless of whether the surveillance device is radiating, hard wired, or turned off.

Efficiency: shorter wavelength of the 2.4 GHz model does better at detecting modern, surface-mounted circuitry in normal office environments

Usability: multiple alert methods are available with a line-of-sight antenna mounted display to allow users to visualize target and display simultaneously

Portability: lightweight design is under three pounds and no assembly is required with an integrated telescoping pole


  • ORION 2.4  HX Touch Screen High Gain G model ** Restricted Model ( 6.6W)

  • ORION 2.4 HX Touch Screen ( 3.3W)

  • ORION 2.4 HX Keypad ( 3.3W)



  • Digitally modulated transmit signal, correlated 2nd & 3rd harmonic response, and adjustable DSP gain provide improved detection & minimize interference (patent pending)

  • Histogram graph displays continuous history of harmonic response and power adjustment (patent pending)

  • Spectrum View (HX models) shows 2nd and 3rd harmonic spectrum graphs in several display options

  • Touch screen displays the full RF spectrum for transmit, 2nd, or 3rd frequency ranges

  • 1.25 MHz-wide bandwidth transmit signal increases detection sensitivity

  • Alert tones and haptic (vibration) alert can be selected to alert when signal levels surpass the trip levels

  • Line-of-sight antenna mounted display and LED head lamp allows user to focus eyes on sweeping target and display at same time, even in dark areas

  • Small, lightweight design weighs only 2.8 lbs/1.3 kg

  • No pole or cable assembly required with integrated telescoping pole

  • A synthesized transceiver with frequency stability and agility to automatically search for clean operating frequencies (2.404 GHz - 2.472 GHz)

  • Circularly polarized transmit and receive antenna removes the risk of missing a threat due to incorrect antenna polarization
