Maintaining corporate security is a complex challenge. And, as electronic eavesdropping devices become smaller, their microphone and camera quality increase, their form factors evolve, and more devices are built to reserve power with inactive or switched off capabilities, maintaining corporate security from the threat of electronic eavesdropping is increasingly difficult. The JJN Digital EDD-24XT Non-Linear Junction Detector NLJD provides detection capability for active, passive and switched off devices in your corporate environment. It’s an important tool in your effort to maintain corporate security!
The EDD-24XT is a powerful, sensitive, high quality, yet lightweight non-linear junction detector for professional TSCM applications. It features an intuitive user-friendly interface, adjustable sensitivity, probability indicator, audio confirmation (via loudspeaker or earphones) and demodulation. The EDD-24XT also features an extension pole and the adjustable head can be set to one of five positions over a 90-degree angle at the push of a button. It makes searching for threats easier and faster for the technical operator.
How Does it Work? It detects semiconductor circuits used in all modern electronic devices, such as mobile phones, tracking devices, listening devices, covert cameras, digital voice recorders, SIM cards, etc. The EDD-24XT NLJD transmits a focused directional signal on 2.4 GHz (ISM Band Type 😎. It receives on 4.8 GHz (Second Harmonic) and 7.2 GHz (Third Harmonic). The highly sensitive receiver will respond to any signals produced on the 2nd Harmonic by even the smallest piece of Silicon, such as that used in SIM Cards, Mobile Phones, Bugging Devices, Voice Recorders, Covert Video cameras etc. And, those devices do not have to be in use, in standby or even have any power connected to them to be detected.
