Classification of access control systems and their applications

As the name implies, the access control system is a system for regulating the entrance and exit channels. It is developed on the basis of traditional door locks. Common access control systems include: password recognition access control system, credit card recognition access control system, biometric access control system and so on.

Password recognition access control system

The access rights are identified by verifying that the entered password is correct. These products are divided into two categories, one is the ordinary type, the other is the out-of-order keyboard type (the number on the keyboard is not fixed, and it changes automatically from time to time). The advantage of password recognition is that it is easy to operate, does not need to carry a card, and has a low cost. The disadvantage is that the security is poor and easy to leak, only one-way control, no door opening record, the button is easy to damage, failure.

　 Swipe identification access control system

According to the type of card, it can be divided into contact card access control system (magnetic stripe card, barcode card) and contactless card (also called proximity card, radio frequency card) access control system. Contact cards are easy to wear due to contact and the information is easy to copy, easy to be disturbed by external magnetic fields, and the use scene is less, generally only used in the case of magnetic stripe cards. The contactless card has the advantages of convenient use, strong durability, fast reading speed and high safety.

Biometric access control system

In and out is identified by examining the biometrics of the person. There are fingerprint type, palm shape, iris type, face recognition type, finger vein type and so on. Its advantage is that it will not be lost, will not be stolen, no memory password burden, safe and convenient. However, the stability and accuracy of biometric identification are still further improved, and the price of products is also higher than the previous two categories. The applicable scenarios also have certain limitations.

New access control system

In recent years, new forms of access control systems such as QR code, Bluetooth, and WIFI have emerged. After the household has verified the identity through the APP, the APP can be opened near the access control machine, and the resident can also generate a QR code image for authorizing the visitor to open the door and share it with the visitor. The visitor's QR code has time and number of opening times.

After more than 20 years of development, the access control system has gradually become a complete access management system. With the continuous development of the security industry, traditional password recognition and card recognition have been difficult to meet market demand. The development and rise of Internet of Things, cloud computing and smart mobile devices have prompted enterprises to develop new products and technologies to gain greater market space. And product profit margins.

What are the applications of the access control system?

1. Application of access control system in office buildings

The installation of access control in the company can effectively prevent foreign sales personnel and other idle personnel, ensure the safety of the company and employees' property, and enhance the corporate image. The attendance management software can be used to improve the efficiency of the personnel department, and the staff level or part of the authority can be flexibly arranged.

2. Application of access control system in community management

The installation of the access control system in the cell can effectively prevent the idle personnel from entering the cell and perform closed management on the cell. Effectively improve community security and reduce security risks. The safe and scientific access control system can improve the grade of the property and facilitate the promotion of real estate. The access control system can also be used in conjunction with building intercom systems, visual intercom systems, and with on-site parking management.

3. Application of access control system in government office

It can effectively regulate the office order, prevent illegal personnel from attacking the government office, and protect the personal safety of the leadership. Sometimes there are more and more people in the office, and the access control system can prevent criminals from stealing information and property. The access control system can also control the entry and exit of the management personnel in different situations through the timed task function, such as the rest time of the Civil Affairs Bureau office hall, the office hall of the Public Security Bureau, and the access control of the working hours.

4. Application of access control system in education and medical care

The installation of an access control system in schools can prevent lawless elements from entering the campus and ensure the safety of students; record student leave and absences. The installation of an access control system in the hospital prevents outsiders from entering the infected area and the precision instrument room, preventing emotional personnel from bringing bacteria into sterile places such as the operating room.

5. Application of access control system in communication base station

The communication base station and the power supply station substation have a wide distribution range and large system capacity. Some places are unattended and require the central control room to mobilize the staff at any time.

6. Application of access control system in elevator control

The access control system is connected to the elevator control and can only be used by authorized users: call and floor; many intelligent communities have increasingly used related equipment, and control circuits are specially designed for elevator control to form a proprietary elevator access control. Control System.

The development trend of access control systems

In recent years, due to the popularity of the Internet and smart mobile devices, the application of the Internet of Things in the field of access control has expanded rapidly. The concept of “smart home” began to slowly enter people's vision. In the stage of diversified development, the company spares no effort to develop products with core competitiveness. The access control system not only has the basic functions of controlling personnel access, but also begins. Integration with other systems, such as video surveillance, building intercom, WIFI probe, security prediction, emergency alarm and other functions. At the same time, in order to meet the needs of customers in different scenarios, major companies began to introduce customized products and services. From the popular access control needs, it has gradually evolved into an access control solution for specific industries.
