At the end of September, according to the principle of voluntariness, the office's coordinator directed the owner of a rental house on Maosheng West Road in Xinmao Village to install a new generation of wireless intelligent access control systems. Subsequently, on the day of the incident, the coordinator recorded information on the rental of the people and found that the system had a red warning signal, indicating that there was a problem with the identity card information of the 207-room tenant Hwang. The office's coordinator immediately notified the police station in the area to the scene for verification. In the afternoon of the same day, the most wanted criminal was captured by the public security police in the absence of preparation.
Today's access control system not only stays in simple access control, attendance registration, but also becomes smarter as the use of access control systems becomes more widespread. In enterprises and cities, the emergence of smart access control systems has brought us Different life experience.
I believe that many office workers have problems with punching cards. They are afraid to miss the punch time at work. Sometimes they are already downstairs. However, when they get to work, many elevators are too late to get on, sometimes even before the punch machine. It is a lot of people, but it is impossible to fight. It is really anxious.
However, in a well-known brand food factory in Qingdao, Lao Wang, who is coming to work, is heading straight toward the workshop where he works. He knew that the voucher card in his pocket would be checked in automatically when he entered the factory.
Pharaoh discovered that since the smart access control system was installed in the factory, the card reader disappeared. He no longer has to crowd at the door of the workshop with his co-workers, eagerly awaiting punches to and from work every day. Therefore, on the way to work and home, Pharaoh and his workers are always a bit more relaxed than the workers in other factories.
Access gates throughout the factory gates, workshops, and other entrances not only save Lao Wang the trouble of punching cards, but also have other features that he enjoys.
Pharaoh pulled out his company’s voucher card from his pocket and said excitedly: “Don’t underestimate this card in my hand, but it's amazing! It can not only punch me, but the problem of overtime can also be managed!â€
According to Lao Wang's introduction, due to the consideration of the health of employees, the factory has defined the working hours of each employee in the intelligent access control system. Once an employee has worked continuously for more than 6 working days, or has accumulated more than 40 working hours per week, smart access control systems have a way to automatically "stop" the employee's work - employees who cannot enter the work area can only go home to rest.
The restrictions on working hours allowed Pharaoh and the workers to realize that overtime was not encouraged. Therefore, the phenomenon of “grinding foreign workers†disappeared. Working hours were fully utilized by everyone and work efficiency was virtually improved. The records linked to the database also make it easy to manage the monthly statistical work.
Page 2: The benefits of smart access control systems are more than that. The benefits of such intelligent access control systems are more than that.
In a large number of employees' factories, there are always hundreds of people who enter the factory at the same time during work hours. How to prevent foreigners from mixing in and out is a matter for companies to scratch their heads. Moreover, in large factories, it is usually not easy to prevent unauthorized personnel from entering key areas such as administrative offices and equipment materials.
However, the deployment of intelligent access control systems has made it easier for security personnel at the factory to work.
In the factory area, each employee's access area has specific restrictions in the voucher card. Those non-authorized personnel who do not have a voucher card in their pockets will be mercilessly rejected by the access control system. Therefore, irrelevant people have no chance at all to walk freely in the factory area.
Once a stranger breaks in, the system's built-in alarm interface can quickly notify the factory of fire, surveillance, security and other related systems. It is rude to say that the smart access control system installed in the factory has built a strong security barrier.
It seems that the wisdom of the access control is like "Transformers 4" inside the KIS Group's heavily guarded high-tech security. However, this kind of magical access control is not the unreal section of the movie, but it is actually present in the daily life of Lao Wang.
Urban Security Smart Access Control is the foundation As an important economic center city and a nationally famous tourist city on the eastern coast of China, the flow of people in Qingdao public transportation systems, commercial areas, gymnasiums and other public places has always been very large. Therefore, smart security is particularly important. In the smart security system, although the access control solution is only part of the "Smart City" system platform, it is the logistical support for the operation of the "Smart City" and the basis of the entire system.
Regarding the way the access control system operates in the "smart city", LID Yang, Product Solution Manager of HIDGlobal explained in detail: "The access control system is integrated with other systems such as surveillance, alarm, firefighting, etc., and will address the safety issue of urban construction." Post-event control "gradually changes to" pre-prevention ", and enhances the city's security and precise management. With the access control system, authorized management personnel can also monitor the entire management area in the data center and truly achieve intelligent security management."
For cities, the choice of “Smart City†partners must consider the security capabilities of products and solutions, while also taking into account other factors, such as smart access control systems and smart systems, intelligent access control systems and other systems. Integration and integration, as well as the ability to achieve security and linkage. Only by satisfying these requirements can the access control system truly meet the needs of the “Smart City†for security, openness, linkage, and expansion.
Page 3: Invisible Authentication
Invisible authentication In the solution of the entire access control system, security identification is the core technology. The operation of a "smart city" and the security of people, money, goods, and information must be protected by it.
For the enterprise, the identity authentication of the access control system can be expressed as a credential card that comes out of the old king's pocket. However, for "smart cities", it is not realistic to issue a physical credential for each person who enters the city to carry identity authentication technology.
Then, what are the ways to achieve the "smart city" identity authentication?
Speaking of this issue, Lu Yang mysteriously said: "The identity authentication technology has some "invisible" bearing methods that can fully meet the needs of building a "smart city." Among them, Near Field Communication (NFC) is a kind of Access control system technology."
Lu Yang's NFC technology is a short-range wireless communication technology that can exchange data with devices within a few centimeters. This technology can be completely embedded in mobile phones, making a portable identity card, so that the authentication method is no longer limited to traditional cards and readers.
An NFC-enabled mobile phone can send authentication information by means of a wireless function. When the mobile phone is near a card reading device, the smart gatekeeper will decide whether to release the line according to the system prompt.
For example, a library bathed in the morning sun, the students holding the self-study materials in their hands came one after another. As they approached the reader at the door, the authentication information on the phone was captured by the reader. At this time, the student's identity information and related materials were read by the system, and the library's sensor door was automatically opened.
Here, the mystery of Lv Yang's tone has not diminished. He continued: "In order to adapt to higher security, access control systems incorporating NFC technology can also use special measures to enhance security."
Lu Yang further explained that the intelligent access control system can use other information technologies to accept various types of keys. For example, we can send the password of a virtual credential card to a mobile phone through the configuration of the cloud or a mobile phone application. This can be a one-time dynamic password or a fixed password set for personal identities.
This configuration mode not only eliminates the risk of the credential being copied, but also enables the issuance of temporary credential cards and the cancellation of lost or stolen credential cards as needed. When necessary, this method can even monitor and modify the security parameters to meet the various services provided by future smart cities based on cloud computing.
Today, virtual credential card technology provides an ideal platform for security management and emerging applications. With the increasing popularity of NFC smart phones, a new generation of virtual credential card technology will usher in large-scale applications. The mobile device embedded with the virtual credential card can not only open access control, log on to the network, electronic payment, ticket service, but also can be widely used in event management.
