Security Technology: Exploring the Comprehensive Development Trend of Access Control Technology

Access Control Technology Comprehensive Development Trend Access control has always been a big market in the field of security technology. Almost every company has its own access control. However, the access control applied in each place is not the same. There are simple, complex, fancy and practical. The world of access control is complex and the world of access control is very simple. So, what exactly is the world of access control? What is the trend of its future development? Today, we come to find out.

First of all, let's first understand what is the origin of the access control. The origin of the access control comes from the Northern Weizheng Tao Yuanshui: “Cao Tzu has taken the Imperial Street and made the entrance ban, which is considered to be thin.” In the modern sense, the access control pointed out that the door access door The prohibition of authority and guarding at the gate is a modern security management system. It integrates the automatic identification technology of the microcomputer and the modern security management measures. It involves many new technologies such as electronics, machinery, optics, computer technology, communication technology, and biotechnology. . It is an effective measure to solve the security management of the entrance and exit of important departments. Access control is widely used in modern society and can be seen in shopping malls, buildings and schools.

In the modern society, what kind of access control has begun to lead the trend?

Access control based on biometrics in modern society has begun to swept the world.

Biometrics technology advances rapidly Biometrics technology has advanced to a higher level Biometrics technology is based on the fact that human biometrics have the characteristics of “everyone is different, lives unchanged, carries around” and uses biometrics or behavioral characteristics to identify individuals. . It mainly includes identification technologies such as fingerprint recognition, face recognition, iris recognition, palmprint recognition, pulse recognition, and ear recognition. Among them, the most widely used is the fingerprint, facial, and iris recognition technologies.

Fingerprint recognition Fingerprint recognition is mainly through the backup of each individual's unique fingerprint, through the texture on the fingerprint to identify a person's identity. The advantages of this method of identification are simplicity, speed, and operability. Only a brief look at the identification version will immediately identify the identity. The general fingerprint recognition machine is compact, easy to install, and has a fast detection speed. It is ideally suited for places where rapid detection is required. For example, company attendance and school attendance are places where it can take advantage. The disadvantage is that the accuracy is not high, errors are easy to occur, and the machine is easily damaged. At present, fingerprint identification is the most widely used type of access control technology. Because of its characteristics, it is widely used for simple attendance.

Facial recognition Facial recognition refers to recognition by human facial features. The advantage of this recognition method is that the recognition speed is fast and the recognition effect is more intuitive. People only need to stand in front of the recognition machine. Your image will be displayed on the screen immediately. It will quickly identify your face and let you quickly pass through the access control. This identification method is very suitable for companies, financial and other fields. However, its shortcomings are very obvious at this stage. For example, in the most basic attendance access control, its price seems expensive. The technical immaturity has also made many customers discourage it. In addition, the large volume is also a big problem. The early face recognition machine was excessively pursuing the intuitive effect. The front monitor was too large and the environment to which it applied was too small. At present, facial recognition technology has been greatly improved in these aspects, and it is also considered by the industry as the best facial recognition technology in the future market. Now, facial recognition technology has begun to expand in building access control, and even in the financial sector, banks have used face recognition to find VIP customers in a timely manner to improve service quality. All these indicate that the market for facial recognition technology is further expanding and the prospects are clear.

Iris recognition Iris recognition is a technique that uses the unique iris in human eyes for recognition. It is currently considered to be the most secure and accurate identification technology. Its advantages are high accuracy and good security. The disadvantage is that the recognition is complex, the recognition speed is slow, and the price is slightly higher than other identification products. Due to the above characteristics, its application market is rather special. It is usually a large-scale secret unit and the critical department uses iris recognition. Access control at the grassroots level, such as schools and companies, is rarely used. However, the industry is still very optimistic about its development, the current iris recognition products have made considerable improvements in the recognition speed, but because the price has remained high, it can not completely occupy the low-end market.

Biometric technology has been wildly raging in the field of access control, but this does not mean that other technologies do nothing in the field of access control, and access control technology based on wireless intelligence is quietly emerging.

Wireless and intelligent leading access control wireless access control technology Wireless access control products from birth to the present, through the continuous evolution of technology has emerged through the FSK, GPRS, Bluetooth, and other transmission products. With the rise of Internet of Things technology, Internet of Things access control products have received widespread attention in the security industry. At present, wireless access control needs to solve the channel problem. As with wireless network surveillance cameras, none of the devices that transmit over the air will be criticized for the signal's vulnerability. In large companies and schools, excessive electromagnetic interference caused by computer appliances will be a major weakness in wireless access control. How to solve this problem will become the bottleneck of its development.

It is true that the major trend in the field of access control today is smart identification as the main direction of development. The traditional card access control seems to be increasingly marginalized. However, it is not willing to be forgotten by people and uses its own innovation to re-awaken people's attention to it. Maybe the company you work for is wired or wireless, and you don't care much, but for the purpose of your access control card, you must be interested. At present, the industry has introduced a mobile phone card mode, which is to make the traditional punch card access control break through in the new environment.

Mobile phone card technology eye-catching mobile phone card has long been applied to other industries. We often see McDonald's customers use mobile phone code to buy food is a mode of mobile phone card. At present, China Mobile's newly introduced mobile phone card integrates internal consumption, attendance, and access control systems, and when the mobile phone is used as an access control card, it truly realizes a multi-purpose card. This not only facilitates the user but also greatly saves resources. It is a good idea in terms of user experience. However, the biggest difficulty of mobile phone cards is system integration. It must have a strong public platform to integrate multiple functions. However, this difficulty is difficult to down the current technology, in the past, China Mobile has launched a new project, can be parking management, water control and other more application subsystems developed, combined with access control attendance, so that mobile phone card The application is more extensive. These sub-functions are extremely attractive for people attending work attendance. Many people who work for parking can use the mobile phone to manage the parking lot in advance and reserve parking spaces. When paying parking fees, you can pay by mobile phone. This saves time, improves efficiency, and improves user experience. This is a fatal temptation for working people.

We know that security system integration is the trend of the entire security industry. The traditional access control system took this focus and advocated innovation. This would be a way to survive in the face of adversity, whether it is a combination of wireless and one-card features, or a traditional access control that focuses on one of them.

to sum up:

The times are always improving, and science and technology will develop a lot of high-tech products centering on people's real needs. In the future, whether it is traditional access control or intelligent access control, only the access control developed around the real needs of humanity will be a good access control. However, the integration of functions and intelligence will certainly be the future direction of development of access control systems.
