The difference between the walk-through mobile phone detection door and an ordinary walk-through metal detector
Everyone knows a little about walk-through metal detector. The common walk-through metal detector on the market are generally ordinary metal detector security gates, also called archway metal detector. For example, the security gates we pass through by subway or high-speed rail are all walk-through metal detector, and walk-through metal detector will not only alarm when metal objects are detected, but also alarm items carried by the human body, which will cause misjudgment and delay time. The walk-through mobile phone detection door mainly detects mobile phones and electronic products with transmission functions. It does not alarm the human body's carry-on items such as necklaces and watches. So, can the walk-through mobile phone detection door also have the effect of security inspection? Let me take you to see the difference between an ordinary walk-through metal detector and a walk-through mobile phone detection door!
Ordinary walk-through metal detector, as long as there are metal objects on the passers' bodies, they will alarm, mainly for metal alarms, so they are also called metal detection security gates. Ordinary walk-through metal detector mainly use magneto-electric compatible dual detection source technology, which can generate an alarm when the human body carries metal objects. It can accurately detect the metal objects carried on the human body or in the body of the hand or the objects containing metal, such as belts, buttons, zippers, keys, controlled knives, weapons, metal products, electronic products, and other items containing metal, etc.
The walk-through mobile phone detection door is mainly used to detect whether the passer-by is carrying a mobile phone. If the passer-by carries electronic products such as mobile phones, notebooks, Pads, mobile hard drives, the mobile phone detection door will alarm, and at the same time, it can not alarm the metal objects carried by the human body. Only alarm for mobile phones and electronic products with the transmission function.
The walk-through mobile phone detection door is mainly detected by eddy current detection and electromagnetic identification induction, micro residual detection, precision filtering, finite element analysis, adaptive and other technologies. It is through comprehensive analysis of a variety of metal substances, plus algorithms Write the program, there are ten detection points on each side of the detection door, a total of 20 detection points, will not send out detection radiation sources to the tested persons, and will not harm the human body.
The walk-through mobile phone detection door is also called the Mobile phone detector security door, the mobile phone detection system and so on. Whether there are mobile phones, cameras, camcorders, laptops, mobile hard drives and other electronic products on the passers-by, whether the above products are on or off, even if the battery is removed or the SIM card is unplugged, it can alarm and display hiding position.
Generally speaking, the walk-through mobile phone detection door can filter out carry-on items, such as metal buttons, metal belt buckles, keys, coins, wallets, cards, lighters, pens and other carry-on items, without warning, including large umbrellas and cups. The walk-through metal detector is a security gate for metal detection. Since the mobile phone also contains metal, the walk-through metal detector can also detect the mobile phone. But for scenes that only want to detect mobile phones, the false alarm rate of walk-through metal detector is very high, almost reaching about 90%, so, compared with the false alarm rate of walk-through mobile phone detection door of about 2%, it is obvious that mobile phone detection doors are targeting mobile phones. It is more practical for mobile phone detection needs.
