Security screening machine can detect what things

1, metal object detection: one of the most common functions of the security check machine is metal object detection. It can accurately identify metal objects carried on the body, such as knives, firearms, explosives and so on. Through the use of electromagnetic induction, X-ray and other technologies, security screening machines can quickly scan the body or luggage for metal objects, and issue an alarm to warn.

2, liquid and gas detection: In addition to metal items, the security machine can also detect liquids and gases. It can quickly detect the possible presence of liquid bombs, flammable and explosive substances, etc., as well as harmful gases such as poisonous and chemical gases through infrared, volatile substance detectors and other technologies. This capability plays a vital role in the security of public **** places such as airports and stations.

3, non-metallic items detection: security screening machines also have the ability to detect non-metallic items. It can scan and analyze luggage, parcels, etc. through imaging technology to discover possible dangerous goods, such as explosives and drugs. At the same time, the security machine is also capable of recognizing prohibited items, such as lighters, knives and scissors.

4, radioactive material detection: security machines also play an important role in security checks, namely, radioactive material detection. It can use equipment such as ray detectors, radiation detection of personnel and goods to ensure that the radiation level of the environment in the safe range. This is particularly important for the safety of public **** premises.

5, image recognition and face recognition: with the continuous progress of science and technology, some advanced security machines are also equipped with image recognition and face recognition technology. These machines are able to authenticate and check people through cameras and algorithms. This plays an important role in security and border control.
