Hefei Metro has launched long-distance detectors, marking a new chapter in intelligent security checks

On April 18, 2025, Hefei Huayuan Metro Station announced the successful commissioning and trial use of the first long-distance detector in China, marking that metro security checks have officially entered a new stage of intelligence and precision. This equipment was developed by Chengdu Taibolai Technology Co., LTD. (” Chengdu Taibolai “). Its highly efficient non-contact detection capability and anti-interference performance provide a brand-new solution for the safe operation of urban rail transit.

During the trial period, this device can quickly identify and locate suspected dangerous objects in the densely populated areas of Hefei Metro, improving the efficiency of traditional security checks by 70%, achieving a “double acceleration” for passenger passage and safety guarantee. Long-distance detectors: Technology empowers Metro safety.

The portable long-range detector tested this time integrates multiple innovative technologies and has the following core advantages:

Super strong detection capability: With a detection range of 5 to 10 meters, it can detect metal dangerous goods hidden in clothes and is suitable for security checks in complex environments with large passenger flows (such as subway stations, etc.).
Strong intelligent recognition capability: Combined with the camera-assisted recognition system, the device can capture the face of a person as they pass by and determine the suspicious nature of the object they are carrying. The response time for face location is controlled within seconds, effectively cooperating with the subsequent alarm judgment process and performing outstandingly.
Easy to deploy and low usage threshold: The entire device adopts a modular design, supporting plug-and-play, and the deployment process does not require complex construction or additional supporting facilities.
Security and efficiency: Supports switching alarm modes between headphones and speakers to meet the flexible needs of security check scenarios; The lithium battery has a battery life of up to 3400mAh, ensuring continuous operation. It has strong continuous operation capacity, does not require frequent charging and maintenance, and reduces the burden on staff.
