An article to interpret the access control system

What is an access control system?

The access control system, as its name suggests, is a system that regulates the entrance and exit passages. It is based on traditional door locks. Common access control systems include: password identification access control systems, swipe identification access control systems, and biometric access control systems.

Password recognition access control system

The entry authority is identified by verifying that the entered password is correct. These products are divided into two categories, one is the common type, and the other is the out-of-order keyboard type (the numbers on the keyboard are not fixed and change automatically from time to time). The advantage of password recognition is that it is easy to operate, no need to carry the card, and the cost is lower. The disadvantage is that the safety is poor and it is easy to leak. It can only be controlled unidirectionally. There is no record of opening the door, and the keys are easily damaged and malfunction.

Card recognition access control system

According to the type of card can be divided into contact card access control system (magnetic stripe card, barcode card) and non-contact card (also called proximity card, radio frequency card) access control system. The contact-used cards of contact products are prone to wear and the information is easily copied and easily damaged due to external magnetic fields. The use scenarios are relatively few. Generally, they are used only in occasions related to bank cards (magnetic stripe cards). Non-contact cards have the advantages of ease of use, strong durability, fast read speed, and high security.

Biometric access control system

Incoming and outgoing are identified by examining the biometrics of personnel. There are fingerprint type, palm shape, iris type, facial recognition type, finger vein type and so on. Its advantages are that it will not be lost, it will not be stolen, it will not be burdened with a memory password, and it is safe and convenient. However, the stability and accuracy of biometrics are still being further improved. The price of the product is also higher than the previous two categories, and the application scenario has certain limitations.

New type of access control system

In recent years, new forms of access control systems such as two-dimensional codes, Bluetooth and WIFI have opened. After the resident verifies his/her identity through the mobile phone APP, he can use the mobile phone APP to open the door near the access control device. At the same time, the resident can also generate the QR code picture for the authorized visitor to open the door and share it with the visitor. The QR code of the visitor has time and the number of opening times is limited. .

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 identification have been difficult to meet market demand. The development and emergence of the Internet of Things, cloud computing, and smart mobile devices have prompted companies to develop new products and new technologies to gain greater market space. And product profitability.

What are the applications of the access control system?

Application of Access Control System in Office Building

The installation of the company's access control can effectively prevent foreign salespeople and other miscellaneous personnel, ensure the safety of the company and its employees, and enhance corporate image. You can use the attendance management software to improve the efficiency of the personnel department, and you can flexibly arrange the level of the company staff or part of the authority to open.

Application of Access Control System in Community Management

The installation of the access control system in the community can effectively prevent miscellaneous personnel from entering the community and conduct closed management of the community. Effectively improve the security of the community and reduce security risks. 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 integration with the management of parking lots in the community.

Application of Access Control System in Government Office

It can effectively standardize office order, prevent unscrupulous personnel from impacting government offices, and protect the personal safety of leaders. Sometimes the number of people visiting the office is more complicated, and the access control system can prevent lawbreakers from stealing data and property. The access control system can also use the scheduled task function to control the access of management personnel in different situations, such as the access control of personnel at break time and working hours, such as the Office of the Civil Affairs Bureau, the Public Security Bureau office lobby.

Application of Access Control System in Education and Medical Treatment

The installation of an access control system in schools can prevent lawbreakers from entering the campus and ensure the safety of students; it records student leave and absenteeism. Installing the access control system in a hospital can prevent outsiders from entering the contaminated area and precision equipment rooms, and prevent emotional personnel from bringing bacteria into sterile places such as operating rooms.

Application of Access Control System in Communication Base Stations

Communication base stations and power supply substations have a wide range of distribution and large system capacity. Some areas are unattended and require central control rooms to mobilize staff at any time.

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 elevators and floor presses; many intelligent communities have increasingly used related equipment, and specifically designed control circuits for elevator control to form proprietary elevator access control systems. Control System.

The development trend of access control system

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 minds. In the stage of diversified development, enterprises have spared no effort to develop products with core competitiveness. The access control system not only has the basic functions of controlling personnel, but has begun to 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 demand for access control, it gradually evolved into access control solutions for specific industries.

However, at this stage, the access control systems developed by most companies are different and independent. In general, these systems cannot share information. Therefore, consumers need to use or download different software or hardware according to different systems. For this issue, the author thinks that the product line is extended. It will be one of the company's future development directions.
