ZJSC-FX881 non-linear node detector

1. Product introduction:
Non-linear node detectors can detect any electronic devices hidden in walls, floors, ceilings, lamps, furniture or containers. Regardless of whether these electronic devices are emitting signals, whether they are turned on or not, they will use display, vibration and sound prompts, etc. A variety of ways to alert, so that the detection personnel can focus on the hidden target. 2.

Third, the use scenarios of nonlinear node detectors
 
1. Government Secret Unit
National government agencies such as public security, justice, prisons, education, troops, large state-owned enterprises, and confidentiality units have very strict requirements for information security and leakage prevention. Before major meetings, confidentiality departments must treat high-level conference rooms, heads’ meeting offices, and foreign guests. Security inspections are carried out in reception rooms, confidential places, etc., to prevent eavesdropping, secret shooting and other illegal equipment hidden in undesirable places, which will eventually lead to the leakage of meeting information, leading to major confidential information and technology leakage, and causing irreparable economic losses to the country and units .
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 all in advance Safety inspections and strict blockades are carried out on the premises. Non-linear node detectors are used to detect bugs, secret shooting equipment, recording equipment, remote explosive devices and other illegal equipment to ensure the safety of the event site.
3. Confidentiality Check of Commercial Organization
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 on internal high-level conference rooms, chairman‘s offices and business negotiation venues to prevent mobile phones and eavesdroppers. Hidden in the wall with other SIM card devices or corners that are not easily found, to ensure that they are not eavesdropped, secretly recorded, monitored, and ensure the security of commercial confidential information during important meetings, major business decisions, business negotiations and other activities. .
4. Anti-cheating inspection in education industry
In places such as college entrance examinations, middle school entrance examinations, civil service examinations, and college scoring, non-linear node detectors can be used at the entrance of the examination room to prevent cheating in the exam. The device can be hidden in the ears, glasses or other parts of the body to ensure the fairness and fairness of the public selection. Fairness.
5. Personal residence or hotel room privacy protection check
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, non-linear detectors can be used to safely detect the surrounding environment to ensure that there are no hidden pinhole cameras, eavesdroppers, and voice recorders. And other electronic equipment to ensure personal privacy and safety.
