Product Description

Product Description

 

Technical Principle

The enhanced nonlinear junction detector emits a fundamental frequency in the S-band from its transmission end. The receiving end captures the second and third harmonics generated by the target object. Using artificial intelligence algorithms to analyze harmonic patterns, it can detect and identify whether there are suspicious electronic products or metal junctions in the detection area. Differential detection principles are also utilized to exclude interference from distant signal sources, allowing for the detection of nearby wireless signals.

Application Scenarios

This device can be widely applied in various fields, including government, public security, prisons, judiciary, commercial security, and personal privacy protection:

• Corporate Confidentiality Protection: Detect unauthorized electronic devices hidden in important meeting rooms or confidential offices, such as listening devices, mobile phones, and devices equipped with SIM cards.
• Police Special Forces Explosive Disposal: Detect electronic detonation devices and remote controls in dangerous areas.
• Personal Privacy Protection: Detect hidden recording and video equipment in residential or hotel environments, such as dictaphones and cameras.

Product Highlights

• Fully Domestic Device: Complete intellectual property rights, not subject to foreign technology import restrictions, with customizable features and optimized algorithms ensuring high security.
• Strong Semiconductor Identification Capabilities: Supports the detection of second and third harmonics, enabling rapid and effective identification of devices containing semiconductors.
• High Wireless Signal Recognition: Can detect and display warnings for wireless signals, including 2.6 GHz, 3.5 GHz, and 4.9 GHz 5G signals.
• High Sensitivity: Built-in high-gain antenna allows for long detection distances, particularly sensitive to SIM card devices, ensuring that secret recording and mobile communication devices can be quickly detected.
• Low False Alarm Rate: The nonlinear  junction detector includes a non-destructive detection algorithm that significantly enhances detection capabilities and reduces false alarms. The wireless signal detection can shield downlink frequencies of communication base stations to avoid interfering with normal signal detection.
• Flexible Operation: Compact size, flexible and simple operation, and excellent user experience.
• High Cost-Effectiveness: Offers good value for money, saving costs while maintaining excellent performance.
