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. -
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 inspections in all places ahead of time and strictly block them. Nonlinear Junction Detectors are used to detect eavesdroppers and secret photograph equipment, recording equipment, remote control explosive devices, and other illegal equipment to ensure the safety of the activity site. -
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 on, not recorded, or not monitored, to ensure the safety of business secret information. -
Cheating Prevention in Education Industry Examination
In places such as college entrance examinations, high school entrance examinations, civil servant examinations, 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 -
Privacy Protection Inspection of Personal Residence or Hotel Room
In order to ensure the safety of personal privacy, non-linear junction detectors can be used to detect the security of the surrounding environment in private spaces such as personal residences, Hotel rooms, shopping mall changing rooms, toilets, and entertainment places, to ensure that there are no hidden pinhole cameras, eavesdroppers, recording pens and other electronic devices to ensure the safety of personal privacy.
Product Characteristics
- Domestic substitution: Completely independent of intellectual property rights, not limited by foreign technology import can quickly customize features and optimize algorithms, with a great security guarantee
- smart ‘shutdown: The device will automatically shut down after 5 minutes of no movement or 5 seconds after the front end is folded, for saving power
- Stronger Semiconductor recognition ability: Built-in spectrum analyzer supporting second and third harmonic detection can quickly and effectively identify devices and devices containing semiconductors.
- High senSitivity: Built-in high-gain antenna, large detection distance, especially for SIM card devices with hint’ sensitivity, to ensure that secrets, mobile communications equipment can be quickly detected:
- lower falSe alarm rate: The built-in non-destructive detection algorithm greatly improves the detection ability, and the false alarm rate is very low.
- High safety and reliability: Th6 characteristics of the equipment meet the requirements of electromagnetic radiation and, are
- Flexible and simple operation: The interface is simple and intuitive, the keys are few and concise, and it is easy to operate manually.

Operation guide
1:Central Control Operating Area
2. Screen The screen interface mainly displays the battery power, alarm mode, transmitting power level, and received second and third harmonic signal strength. The detecting process and result are as below:
Battery status display
The audible alarm mode indicator
Indicates that an electronic product has been detected
Vibration alarm mode
The headphone mode indicator
Indicates that the device is in the process of detection
Transmitting power intensity indicator
Indicates the received second harmonic signal strength
Indicates the received third-order harmonic signal strength
When a suspicious electronic device is detected in the target area, the second
harmonic signal strength is significantly stronger than the third harmonic
signal strength, and the electronic product icon is displayed on the screen.
3. Charging instructions:
The device supports charging using the Type C interface. The indicator light
of the power button will always be orange when charging, and the battery icon
will be shown as charging status on screen if the device is on.
FAQ
Q: Can’t boot when I press the power key, how to deal with it?
A: Normal booting requires long press of the power key for more than 3s; if
you press and hold the power key for 3s, it still cannot be turned on. It may
be caused by the battery being exhausted. You need to connect the power
adapter to charge.
Q: How to detect target electronic products that are far away?
A: Increase the TX Power; or increase the RX Gain
Q: Electronic products have been detected but there is no sound alarm, how
to deal with?
A: 1. It is possible to set the machine to silent mode, and you need to exit
the silent mode to generate an audible alarm; 2. Turn up the sound; 3. Check
the horn for blockage.
Q: When the machine will auto shut down?
A:
- After the machine head is folded, it will auto shut down after 5 seconds;
- If the machine detects that it has not moved for 5 minutes, it will auto shutdown;
- When the battery power is lower than 10%, the machine will auto shut down.
0: After the box is transported or stored for a long time, there may be a
phenomenon that it cannot be opened or deformed. How to deal with it?
A: This situation is caused by the change of the air pressure difference
inside and outside the box. The pressure reducing valve can be rotated to make
the internal and external air pressures uniform, then the box can be opened,
and then the pressure reducing valve can be tightened to avoid water leakage.
