In addition to X-ray machines, metal detectors, intelligent security gates and other security devices, the Beijing railway system also applies other security devices to ensure the safety of passengers and trains.

Among them, representative security inspection equipment includes:
Handheld metal detector: This device is usually used to inspect passengers' personal belongings to discover hidden metal items.
Explosive detector: This type of equipment can detect explosives and other hazardous materials, usually installed in important areas of stations and on trains to ensure the safety of passengers.
Thermal imager: This device can detect dangerous items such as firearms and knives hidden in the human body through thermal sensing technology.
Drug detector: This device can detect prohibited substances such as drugs and is usually used to check the personal belongings of passengers.
Biometric technology: This technology can verify the identity of passengers through facial recognition, fingerprint recognition, and other technologies to prevent unidentified individuals from entering stations and trains. The widespread application of these security equipment can improve the efficiency and accuracy of security checks, ensuring the safety of passengers and trains. At the same time, the Beijing railway system is constantly upgrading and improving the application of security inspection equipment and technology to adapt to the constantly changing security environment and threats.
