About Us 公司介绍
Who We Are
Zhongshan Jinshijie Electronic Technology Co., Ltd. is based in Zhongshan, Guangdong, China. We specialize in the R&D, manufacturing, and sales of information security products, delivering professional security solutions to our clients. Our business covers three core areas: anti-recording protection, anti-spy-camera / electromagnetic security, and OEM customization.
Manufacturing Capability
We operate a modern, highly self-controlled production facility equipped with SMT workshops, DIP assembly lines, SPI and AOI inspection equipment. This allows us to handle both standardized bulk production and customized orders, with centralized quality control from raw materials to finished products — smart manufacturing, rigorous testing.
Anti-Recording Solutions
Our anti-recording products mask voice while minimizing impact on normal conversation and office environments. They protect business secrets and personal privacy in meeting rooms, offices, and research labs. The core technology uses ultrasonic frequency (>20kHz) directional sound, dynamic random noise generation, and nonlinear acoustic mixing — precisely controlled by algorithm so that recording devices cannot filter or reverse-engineer the interference. Ultrasonic signals are imperceptible to the human ear.
Anti-Spy-Camera / RF Detection
We provide comprehensive technical services based on radio frequency (RF) detection, optical auxiliary inspection, and physical surveys. This service locates and identifies hidden unauthorized cameras in hotel rooms, changing rooms, and meeting spaces. Detection methods include wireless RF signal detection, near-field electromagnetic probing, and optical reflection detection — a professional security audit integrating radio engineering, electromagnetism, and information security.
OEM Customization
We offer flexible OEM services: custom design, development, production, and private-label manufacturing based on client requirements. We tailor functions and appearance to meet specific application scenarios — not just a manufacturer, but a strategic partner.
关于我们
中山市金士界电子技术有限公司位于中国广东省中山市，专注于信息安全产品的研发、生产与销售，为客户提供专业的安全信息解决方案。业务涵盖三大板块：防录音安全、防偷拍电磁安全、OEM定制。
生产实力
我司拥有现代化且高度自主可控的生产实力，配备SMT车间、DIP装配部，以及SPI和AOI等检测设备，可满足客户标准化批量生产及定制化服务需求。从原材料到成品实现集中管控、智慧化生产、高标准检测。
防录音安全服务
在实现声音掩蔽的同时，尽量减少对正常交流和办公环境的影响。既可保护商业秘密，也可防止个人隐私被窃听，广泛应用于会议室、办公室、研究实验室等需要保护语音隐私的场所。核心原理采用超声频段（>20kHz）定向声技术，结合动态随机噪声生成技术与非线性声学混频技术，干扰信号的频率和强度由算法精准控制，避免被录音设备反向过滤或破解。超声波对人耳无感知。
防偷拍电磁安全服务
基于无线电频率（RF）探测、光学辅助检测与物理勘查的综合专业技术服务，核心目标是探测、定位并识别未经授权的隐藏式摄像设备，保护个人隐私和商业机密。主要手段包括：无线射频信号探测、电磁场近场探测、光学反射探测，融合无线电工程、电磁学、信息安全及现场勘查技术，提供技术可靠、流程规范、结果可信的主动防御解决方案。
OEM定制服务
根据客户提出的具体需求，提供人性化设计、开发、生产和贴牌制造合作模式，灵活定制，实现功能差异化。我们不仅是制造商，更是您值得信赖的战略合作伙伴，将您的创意和品牌转化为具有市场竞争力的优质产品。
