Recently, an innovative drone-mounted positioning device has been deployed for practical use by multiple emergency management and law enforcement agencies. The system utilizes a drone platform equipped with specialized positioning equipment to rapidly search for and locate mobile phone signals of target individuals in inaccessible areas, providing critical technical support for emergency rescue and law enforcement operations. In scenarios such as natural disaster response and counter-terrorism operations, traditional search and rescue methods are often limited by terrain, environmental conditions, and safety risks. The newly introduced drone-mounted positioning system effectively addresses these challenges. By accurately capturing mobile phone signal characteristics, the system enables rapid positioning within a kilometer-level range, even in areas without network coverage, delivering real-time data for mission decision-making. Core Features of the System: (1) Wide-Area Search: A single mission can cover signal scanning across a 10-square-kilometer area, with a maximum altitude of 500 meters. (2) Precise Positioning: Utilizing multi-technology fusion positioning, the system achieves positioning accuracy within 50 meters. (3) Rapid Response: From deployment to acquiring the first set of positioning data, the process takes no more than 15 minutes. (4) High Adaptability: Capable of operating in complex terrains and under harsh conditions such as rain, snow, and sandstorms. A staff member from a provincial emergency rescue team stated: "During a recent mountain rescue operation, the system successfully pinpointed the exact location of missing climbers, improving efficiency by more than five times compared to traditional search methods. Particularly in hazardous areas such as cliffs and flood zones, the drone-mounted equipment demonstrated irreplaceable value." The successful application of this device marks a significant breakthrough for our company in the field of mobile terminal positioning technology. In the future, we will continue to deepen collaborations with emergency management and public safety departments, promoting the intelligent advancement of drone-mounted systems and contributing technological strength to safeguarding public safety.

In a significant step toward enhancing security measures, a state-of-the-art Nonlinear Detection Device has been successfully deployed at a confidential facility in Singapore. This cutting-edge system is designed to detect unauthorized recording or surveillance devices, ensuring the utmost protection of sensitive information during high-stakes meetings and operations. The increasing sophistication of miniaturized espionage devices, such as hidden cameras and audio recorders, poses a serious threat to organizational security. Traditional methods of sweeps and physical inspections often fall short in identifying these covert tools. The newly implemented Nonlinear Detection System addresses this challenge by leveraging advanced semiconductor detection technology to identify electronic components commonly used in illicit recording devices. How It Works: The system emits low-power radio frequency signals that interact with semiconductor materials within electronic devices. When a suspicious device, such as a hidden camera or audio recorder, is present in the monitored area, the system captures the unique nonlinear responses generated by its semiconductors. This triggers an immediate alert, notifying security personnel to take action. Key Features and Benefits: (1) Precision Detection: Capable of identifying even the smallest semiconductor-based devices, including those that are powered off or in standby mode. (2) Real-Time Alerts: Instant notifications with location details enable swift response to potential threats. (3) Non-Intrusive Operation: The system works discreetly without disrupting ongoing activities or compromising the privacy of authorized personnel. (4) Adaptability: Customizable settings allow it to function effectively in diverse environments, from boardrooms to critical infrastructure facilities. The deployment of this system at a Singaporean confidential unit marks a milestone in the integration of technology and security. A representative from the facility praised the system, stating, "The Nonlinear Detection Device has revolutionized our security protocols. Its ability to detect covert devices with pinpoint accuracy provides unparalleled peace of mind during sensitive operations." This achievement underscores our commitment to delivering innovative solutions that address evolving security challenges globally. As threats to confidentiality become more advanced, our team continues to push the boundaries of technology to protect what matters most.

Recently, the intelligent security detection product independently developed by our company, the "Secret Guardian" system, has been deployed and officially put into operation in the core confidential meeting rooms of several key clients. With its precise and efficient ability to detect unauthorized of mobile phones, the system has garnered high recognition and unanimous praise from the security departments of client organizations, significantly enhancing their technical confidentiality capabilities. With the rapid development of mobile communication technology, the risk of information leakage posed by mobile terminals such as smartphones has become increasingly prominent. Especially in meeting rooms involving core secrets, strictly prohibiting the of mobile phones has become a fundamental confidentiality rule. However, traditional manual inspection methods suffer from inefficiency, susceptibility to oversight, and poor user experience. The emergence of the "Secret Guardian" system aims to address this issue by providing unmanned, round-the-clock, and intelligent technical control measures for high-level confidential spaces. The "Secret Guardian" system employs advanced radio frequency signal detection and identification technology to enable non-contact and imperceptible real-time monitoring of mobile phone signals within specific areas. Once a mobile phone is detected to be illegally brought into a protected confidential meeting room, the system immediately triggers a precise alarm. The core features and advantages of the system include: (1) Precise Identification: Not only can it detect the presence of mobile devices, but it also accurately captures and displays the International Mobile Subscriber Identity (IMSI) of the device, providing irrefutable technical evidence for post-incident tracing and accountability. (2) Real-Time Alerts: Alarm information (including trigger time, location, IMSI data, etc.) is instantly pushed to the security management platform and displayed through various forms such as sound, light, and pop-up notifications, enabling a response within seconds. (3) Discreet Deployment: Detection terminals can be flexibly and discreetly installed without affecting the overall environment or aesthetics of the meeting room. There is no need to change user behavior, greatly improving user experience and acceptance. (4) Stability and Reliability: After rigorous environmental testing and optimization, the system exhibits strong anti-interference capabilities, stable operation, and an extremely low false alarm rate, effectively ensuring the seriousness and security of confidential meetings. Since its deployment, the "Secret Guardian" system has become an indispensable "electronic sentry" for the confidentiality management of client organizations. A security  from one client : "This system is highly sensitive and intelligent, like having a tireless 'guardian spirit' for our confidential meeting rooms. It transforms our work from passive inspection to proactive , significantly improving management efficiency and security levels. It provides robust technical support for strictly upholding confidentiality bottom lines." The successful application of the "Secret Guardian" project fully demonstrates our company's profound technical expertise and innovation capabilities in the fields of information security and radio frequency identification. It is not merely a product but a perfect embodiment of our philosophy: "customer-centric, safeguarding security with technology." In the future, our company will continue to advance the development of the "Secret Guardian" system, expand its application scenarios, and strive to provide more diverse and advanced holistic confidentiality solutions for our clients, contributing to the protection of national and enterprise secrets with even greater impact.
