Nonlinear Junction Detector

How is this Nonlinear Junction Detector work?

Nonlinear junction detector emits S-band fundamental wave to the target area or object, and the receiver captures the second and third harmonics generated by the target object. Artificial intelligence algorithm is used to analyze the harmonic law, so as to detect and identify the electronic equipment with non-linear junctions.

 

Where is this Nonlinear Junction Detector mostly used?

1. Government Bureaus

National government bureaus such as police, justice, prisons, education, troops, and confidentiality bureau have strict requirements for information security and leakage prevention. Before major meetings, confidentiality departments must check the high-level conference rooms, chief officer’s meeting room, and foreign guests reception room to prevent eavesdropping, secret shooting and other illegal equipment hidden in undesirable places which will lead to the confidential information, technology leakage, causing irreparable economic losses to the country.

 

2. Security inspections for large-scale events

At the large-scale international summits, business negotiations and other large-scale events initiated by the country and local municipal governments, in order to ensure the personal safety and information security of politicians, business leaders and participants in various countries, the organizing committee needs to appoint a professional security team to carry out safety inspection in advance and strict blockades are carried out on the premises. Nonlinear junction detectors are used to detect bugs, secret shooting equipment, recording equipment, remote-controlled explosive devices and other illegal equipment to ensure the safety of the event site.

 

3. Confidentiality inspection of commercial organizations

In order to ensure that trade secrets are not leaked, large commercial organizations such as listed companies, multinational companies, and industry associations need to conduct strict information security checks at internal high-level conference rooms, chairman’s offices and business negotiation venues to prevent mobile phones and eavesdroppers and other SIM card devices hidden in the wall or corners which are not easy to find out. With the Nonlinear Junction Detector to ensure that it will not be eavesdropped, recorded or monitored in the important meetings, major business decisions, business negotiations and other activities, to make sure the security of commercial confidential information.

 

4. Anti-cheating inspection in education industry

In places such as college entrance examinations, middle school entrance examinations, civil service examinations, and college scoring, the nonlinear junction detector can be equipped at the entrance of the examination room to prevent cheating in the exam which the device mostly will be hidden in the ears, glasses or other parts of the body, try to ensure the fairness and impartiality of public selection.

 

5. Personal residence or hotel room privacy protection inspection

In order to ensure personal privacy and security in private spaces such as personal residences, hotel rooms, shopping malls changing rooms, toilets, and entertainment venues, the nonlinear junction detector can be used to safely detect the surrounding environment to ensure that there are no hidden pinhole cameras, eavesdroppers, voice recorders, and other electronic equipment to ensure personal privacy and safety.
