Detail

Made in CHINA

Brief introduction

It can detect any electronic equipment hidden in walls,floors,ceilings,lamps,furniture
or containers.Where these electronic devices are transmitting singers or not,they are alerted by display,vibration and sound prompts,so that the detectors can focus on hidden taigets.

Tusage scenarios of Nonlinear Junction Detector

1.    Government Secrecy Department

State government organs such as public security, justice, prisons, education, troops, large-scale central enterprises and secret-keeping units have very strict requirements on information security and leak prevention. Prior to the major meetings, the secret-keeping departments must conduct security tests on high-level conference rooms,head leader’s meeting offices, foreign guests; reception rooms and secret-keeping places, so as to prevent the hiding of illegal equipment such as eavesdropping and secret shooting from being inappropriate places. Findings eventually lead to the leakage of conference information, major confidential information and technology, and irreparable economic losses to the state and units.

2.    Security Inspection of Large-scale Activities

In order to ensure the personal safety and information security of politicians, business leaders and participants, the organizing committee needs to appoint a professional security inspection team to conduct security inspection in all places ahead of time and strictly block them. Nonlinear Junction Detectors are used to detect eavesdroppers and secret photographs equipments, recording equipments, remote control explosive devices and other illegal equipments   to ensure the safety of the activity site.

3.    Confidentiality Inspection of Commercial Organizations

Large commercial organizations such as listed companies, multinational corporations, trade associations and so on, in order to ensure that business secrets are not leaked, need to carry out strict information security checks on internal high-level conference rooms, chairman’s offices and business negotiation venues, to prevent mobile phones, eavesdroppers and other SIM card devices from hiding in the wall or hard-to-find corners, and to ensure that important meetings and meetings are being held. Big business decision-making, business negotiation and other activities are not eavesdropped, not recorded, not monitored, to ensure the safety of business secrets information.

4.   Cheating Prevention in Education Industry Examination

In places such as college entrance examination, high school entrance examination, civil servant examination and college marking, non-linear junction detectors can be used at the entrance of the examination room to prevent cheating devices from being brought into the examination room by hiding in the examinee’s ears, glasses or other parts of the body, so as to ensure the fairness and fairness of the open selection.
