Why need to be installed security screening and detection equipment?
From applications:
Customs ports: There are a large number of cargo turnover and personnel movements every day at seaports and land borders crossings. The goods are turned around at various border crossings around the world, which promotes the development of global trade and economy. Checking for prohibited items or dangerous goods hidden in cargos has always been the biggest trouble and urgently needed to be solved. Combating smuggling and detecting dangerous goods are important for protecting legitimate trade and safeguarding national security.
Civil Aviation: Since the "9.11" incident in the United States, airport security inspections have been upgraded to the highest security level, how to quickly and effectively screening and detection for contraband and threats hidden in air cargo, passenger luggage and the body, for public safety and maintenance of the country safety is very important.
Rail transit: There are a large number of passengers and cargo turnovers every day in major railways (train stations), highways, and metro stations. Due to the closed space and the large passenger flow, urban rail transit is more likely to cause terrorist attack. Prevent dangerous goods or threats enter from being carried in advance, it's effectively control the occurrence of vicious incidents.
Public Security and Law Division: With the increasingly prominent social contradictions, the anti-terrorism situation is becoming increasingly serious. Public security agencies, courts, procuratorates, prisons and other government departments frequently violent crimes and illegal acts, resulting in huge personal and property losses. In order to prevent and stop the violent incidents such as explosions, shootings, and murders, the number of security screening equipments needs to be installed in time.
Large-scale events: big games, plays or concerts, accommodating hundreds or thousands of people in a limited space. Intensive population, any dangerous goods or violent incidents may cause panic and stampede in a large number of people. It is very important to strictly scan and check people and items at the entrance.
Special places: hotels, churches, museums, scenic areas, banks, shopping malls, embassies, government buildings, etc. Due to the special sensitivity of the site, the complexity of visitors, the violent crimes and threats are constantly changing. Demanding for a comprehensive security screening and inspection solution is becoming more and more urgent.
Postal Logistics: The logistics system delivers different sizes of parcels and cargos every day, including hidden dangerous goods such as flammable and explosive batteries, smuggled goods or drugs. A large number of parcels cannot be checked out one by one, and only a security scanning system can be faster and more efficient and check whether each parcel is safe.
Which kinds of security screening and detection equipments are available in the market?
From solutions:
Safe of person: Except the way to check personal ID card or Passport whether the person had engaged in illegal criminal activities, it is necessary to confirm whether the person has hidden dangerous goods to enter into a public place with a large flow of people. Most dangerous goods consist of ferrous metals and non-ferrous metals, such as guns, knives, and explosives. Passing through the walk through metal detector (also named: door frame metal detector) security door and the accurate inspection of the body parts by hand held metal detector(also named: portable super scanner, security wand), it’s a effectively way to prevent and stop the entry of personnel carrying dangerous metal articles.
Safe of baggage or parcel: Baggage x-ray scanner machine (also named: security screening system, security x-ray inspection system, x-ray baggage scanner, x-ray baggage detector) penetrates the baggage by emitting X-rays to obtain a clear scanned image. Judging whether the dangerous objects and suspected explosives and drugs are hidden from checking the shape and color of the objects in the scanned image. At the same time, suspicious baggage or parcels can be re-inspected with explosives and narcotics detectors (also named: bomb detector). If a person has been exposed to explosives or drugs, the body and clothing will leave molecules, and the Nanogram-class explosive detector can be traced the molecules. Effective prevention of human bomb explosions. If we found some unknown solids, powder and liquids, such as narcotics, explosives, threat chemicals and so forth. Based on Raman spectroscopy of molecular identification, handheld chemical identifier provides a reliable and precise result with a large and extensible database.
Safe of vehicle/car: car bombs or smuggling or escapes, usually choose to hide items and people in the chassis (under vehicle). The traditional inspection method works with under vehicle inspection mirror or under vehicle search camera to check the vehicle undercarriage or beneath of vehicle step by step. Efficient inspection method adopt under vehicle surveillance system (also named: under vehicle monitoring system, under vehicle inspection system, under vehicle scanning system, UVSS,UVIS), get the complete vehicle chassis image in one second, and the high-definition picture can be enlarged for detailed viewing.
