People screening can visually display information based on the doorpost lights on both sides of the area where the prohibited item belongs. People screening can conveniently and reasonably check the illegal equipment and electronic components such as controlled knives and firearms, copper, tin, zinc and other precious metals. People screening is used to ensure the safety maintenance of public places and corporate anti-theft.

Which metal can be detected by people screening?
We all know that public places, especially subways, stations, airports, and courts, must pass through people screening for inspection. So what items can the people screening detect?
Theoretically speaking, it is not allowed to carry except for luggage and clothing. The latest regulations on passengers are strictly prohibited from carrying:
l Explosive items: fireworks, explosives.
l Corrosive materials: waste batteries, sulfuric acid, sulfur.
l Toxic substances: pesticides, drugs, pesticides.
l Combustible gas: hair spray, pesticides, all compressed gas cylinders and plastic bottles.
l Flammable and explosive liquids: gasoline, paint, milk, alcohol.
l Radioactive materials: shafts, rings, lithium batteries.
l Control knives: daggers, bayonets, fruit knives, nail clippers, scissors.
So the above that people screening can detect are prohibited to carry, and some are prohibited items. Once the prohibited items are discovered, not only are you confiscated, you will also face the dilemma of fines or detention.
Some prohibited items that people screening can also detect include all explosives such as guns, ammunition, fireworks, detonators. The above listed are not allowed to appear in public transportation, as well as all corrosive acidic toxic gas liquids.
What performance can be used to value people screening?
Most countries are also paying more and more attention to security checks. The people screening plays a very important role in the entire security process. The problems of people screening mainly reflect in false alarms, which are due to insufficient sensitivity or poor anti-interference ability. In addition to the important indicators of false alarms, there are other technical performances to measure the advantages of a people screening, which are also important parameters.
Precise positioning: There are precise positioning lights on both sides of the people screening to visually display the position of the target, which is convenient for the operator to check further.
Prevent two kinds of metal induction cancellation function: Because the detection principle of the people screening is that when a metal object passes through, the original magnetic field is changed and it is detected. However, the induced magnetic fields generated by different types of metals may cancel each other out. The people screening must adopt special technology to prevent this from happening.
Sensitivity is adjustable: You can adjust the sensitivity of people screening to meet the security requirements, but too high sensitivity will reduce the anti-interference ability.
How to deal with the condition when people screening is interfered?
Mechanical interference: Revolve people screening. A distance of 10m should be maintained between the detector and the people screening. Please make sure that the people screening opens outwards. If there are two doors, then the detection door should be installed on one of the doors, and lock the other door tightly. If it is a metal door, cut off a corner of the metal door frame to isolate its metal ring. After the detector is installed, please turn the people screening back and forth to check the installation effect of the people screening.
Electronic interference: For moving objects, if the people screening is installed too close to the roadside, large vehicles passing by may affect its normal operation. If you want to reduce the false alarm rate, you have to find out the cause of the false alarm. Since the people screening uses bilateral transceiver technology, any electromagnetic source and electromagnetic radiation source should not be close to the people screening. Vibration of the floor, strong outdoor wind, and slight swinging of the door body will affect the normal operation of the people screening. Keep away from large metal objects and pay attention to the impact of rolling shutters, iron anti-theft doors and gate mesh iron doors on the people screening to avoid false alarms.
