Non-linear Junction Detector Orion 2.4

Orion 2.4 attempts to steal vital business or private information are becoming more and more frequent. It is hardly a surprise, since access to a company's strategy guidelines might translate to income measured in millions, while sensitive data might be used for blackmail. To deal with threats posed by advanced surveillance instruments, Research Electronics International constructed the non-linear junction detector Orion 2.4.

Orion 2.4 emits a 2.4 GHz signal, which stimulates non-linear junctions – semiconductor junctions present in every piece of electronic equipment. Junction stimulation creates electromagnetic harmonic waves, which are in turn picked up by the receiver. Strong response in 2nd harmonic frequency indicates presence of devices potentially used for surveillance. Harmonic waves are a phenomenon independent from operation of the device, meaning it does not have to be active or even powered (!) to be localised.

The non-linear junction detector is a perfect tool for inspection of vital spots in companies, banks, conference halls, house rooms, or correctional facilities.

Key features of Orion 2.4 detector

  • Wired wiretap

    Detecting surveillance devices of any kind

    Detects devices regardless of utilised technology, even concealed in building structure elements:

    • listening devices
    • cameras
    • mobile phones
    • chip cards
  • Zoom

    Detection of miniature listening devices

    The antennas of Orion 2.4 allow to sweep tight spaces and detect miniature surveillance devices.

  • Brightness regulation

    Pinpoint bug localisation

    Allows to determine the location of a surveillance device, whether it is active or not.

  • Able to locate even sim cards

    Able to locate even sim cards!

    The 2.4GHz work frequency allows to detect objects as SIM card.

  • Digital modulation and correlation

    Digital modulation and correlation

    Modulated transmit signal with correlated second and third harmonic response provides ensures improved detection and reduced interference.

  • Automatic frequency adjustment

    Automatic frequency adjustment of the non-linear junction detector

    Automatic seeking of optimal frequency in 2.404 – 2.473GHz range. The device selects the most favourable frequency, depending on external interference.

  • Circularly polarized transmit and receive antenna

    Circularly polarized transmit and receive antenna

    Reduces the risk of missing a potential listening device due to incorrect polarization of the antenna.

  • High detection sensitivity

    High detection sensitivity

    High sensitivity of detection – 1.25 MHz bandwidth.

  • Long range detection

    Long range detection

    Output power adjustment – up to 3.3 W. Manually adjusted or automatic.

  • Highly stable work frequency

    Highly stable work frequency

    Non-linear junction detector allows for uninterrupted and unhindered operation.

  • Receiver system

    Receiver system

    Very high sensitivity -140dBm for 2nd and 3rd harmonics.

  • Alarm


    USB 2.0 interface enabling communication with computer - in Pro version.

  • Colour display

    Colour display

    Bar display for 2nd and 3rd harmonic levels. The display remains in the operator's field of view during sweeping.

  • Telescoping pole

    Telescoping pole

    Lightweight and convenient, needs no additional tools or assembly.

  • Mobile construction

    Mobile construction

    The non-linear junction detector is powered with Li-Ion batteries. The set includes 2 batteries, each allowing for 5 hours of continuous operation.
