WTMD Safeguards Public Security: EASTIMAGE MD3000 Deployed at Supervision Facilities Across Multiple Regions

WTMD: The "Invisible Guardian" of Public Safety

WTMD, short for Walk Through Metal Detector, is an indispensable security inspection device in the field of public safety. Its operating principle is based on electromagnetic induction: the internal transmitting coil generates a low-frequency alternating electromagnetic field. When a person carrying metal objects passes through, the metal induces eddy currents and forms a reverse electromagnetic field, which interferes with the original electromagnetic waves. The receiving coil detects this change and converts it into an electrical signal, which is then analyzed by the signal processing unit. If the signal intensity exceeds the preset threshold, an alarm will be triggered. Modern WTMDs mostly adopt multi-zone design; they can independently detect through coils in different zones to roughly determine the position of metal objects on the human body. They also have sensitivity adjustment function, which can selectively ignore small metal items such as coins and keys, and only alarm for dangerous items like knives and guns.

EASTIMAGE MD3000 Successfully Deployed at Multiple Supervision Facilities in Shanghai in Q4 2025

In the fourth quarter of 2025, good news came from the public security cooperation field — EASTIMAGE, a professional supplier of walk through metal detectors, has successively reached cooperation agreements with key public security venues including Shanghai No.4 Detention House and Songjiang Detention Center, relying on its high-quality security gate solutions. Its EI-MD3000 metal detector gate has been successfully installed, commissioned and put into use. Supervision facilities such as detention houses and detention centers have complex personnel flows and extremely high requirements for security inspection accuracy and efficiency. EASTIMAGE EI-MD3000 can efficiently screen out dangerous metal objects by virtue of its core advantages such as precise positioning and high sensitivity adjustment, effectively reducing potential safety hazards and has won high recognition from cooperating units.

EASTIMAGE Provides Solid Security Support

As a professional supplier of walk through metal detectors with over 10 years of experience in the security inspection equipment industry, Shanghai Eastimage Imaging Equipment Co., Ltd. (EASTIMAGE) is a national high-tech enterprise. Adhering to technological innovation as its core, the company has built a full-chain service system covering R&D, production and sales of security gates. With excellent product quality and rich project experience, EASTIMAGE's security inspection equipment is not only widely used in public security places such as detention houses, courts and police stations, but also deployed in transportation hubs like airports and railway stations. It has successfully provided security inspection support for major events such as the Beijing Olympic Games and Shanghai World Expo.

Conclusion

The deployment of EASTIMAGE EI-MD3000 security gates at multiple supervision facilities in Shanghai is another important achievement of the company's deep cultivation in the public security field. In the future, as a professional supplier of walk through metal detectors, EASTIMAGE will continue to focus on the R&D of security gate technology, optimize the performance of core products such as EI-MD3000, launch more walk through metal detector solutions adapted to different scenarios, provide more accurate and efficient security inspection support for various venues including detention houses, courts and airports, and contribute to the continuous upgrading of the national public security system.
