Explore the function and classification of access control looking for ordinary security
2016-05-03 00:00
When it comes to the function of the access control system, many readers may think: access control, it must be blocking people. So, let's take a look at what tasks today's access control systems have inadvertently accomplished?
Basic functionality
(1) For our ordinary residents, that is, familiar people can pass, and strangers cannot pass.
(2) For some places with higher security levels, it means more detailed divisions, such as what kind of people can pass, what level of people restrict access, and so on.
In general, setting permissions and distinguishing personnel are the main goals under the basic working ability of the access control system.
Real-time monitoring capabilities
Speaking of the implementation of monitoring functions, different access control equipment naturally has different access control monitoring effects. For some areas with video display, managers can view the entry and exit of personnel in each door area and the status of each door area in real time through the microcomputer, including the opening and closing of the door, various abnormal state alarms, etc. At the same time, in the event of an emergency, the initial control of the event can also be realized by adjusting the opening and closing of the gate. From these aspects, the application of access control is no longer just as simple as guarding.
In addition, the monitoring ability of the access control system is also reflected in the management of access control use, such as information query, recording, screening, etc. of all incoming and outgoing personnel, or the realization of some attendance management and other behaviors.
Swipe access control system
When it comes to swipe access control systems, it can be said that there is basically nothing unfamiliar to everyone. At present, because the password access card has become more and more difficult to meet our daily security needs, and the biometric access control system is often "too sensitive" to make us trust. Therefore, the swipe access control system has become the main force of our application.
At present, swipe access control systems are divided into two categories, namely contactless access cards and contact access cards. However, due to the high frequency of wear and fragility of contact access cards, the application field is gradually shrinking. It's just that some bank ATMs, or some simple internal control links, are still used in small quantities.
Non-contact IC cards occupy the mainstream of the current access control system with their durability, good cost performance, fast reading speed and high security. Therefore, at present, many people refer to the contactless IC card access control system as an access control system.
Biometric access control system
Speaking of biometrics, it is definitely a source of concern throughout the security field. Although technically there are still many links in the early stages of experimentation, this still does not shake everyone's interest in it. According to the different positions of the human body, biometric access control has also launched different recognition technologies, such as fingerprint access control to identify fingerprint differences, palm access control to identify bone differences, iris access control system to identify retinal and face recognition system to identify facial features.
The advantages of this type of system are low repetition rate, excellent work efficiency, and security.
RFID access control equipment
As access control equipment gradually presents in a systematic form, the security capabilities it embodies are more comprehensive and intelligent. Nowadays, in some advanced access control systems, there are good solutions to prevent illegal intrusion and prevent criminals from infiltrating with the help of time difference.
For example, through the analysis of the cardholder's trajectory, etc., determine the route he enters, and open the door permission that he may pass through to avoid illegal intrusion caused by card theft or other unexpected circumstances. Or in some access control, the coordination between the access control systems can be maintained to ensure that the second door can be opened when the other door is closed normally. There are also some access control systems that can use a special door opening method when the user is in danger, which not only ensures the personal safety of the passer, but also quietly completes the alarm.
Although in our daily use, the access control system with alarm function is still more in the more professional application field, but we still cannot ignore its important role in the self-improvement of simple civilian equipment.
epilogue
Today, the access control industry has been parallel to our lives for many years.
In these years of application, the access control itself has also continuously achieved self-improvement and updating, which has brought us more security technology applications. Although from the perspective of application fields, there is still a big gap between civil equipment and access control systems in some professional fields. However, their attempts in different environments are an indispensable and important process in the overall development of access control technology.
Therefore, in the face of these seemingly distant new technologies, we do not need to complain about their overmodernity and alienation from us, because perhaps at any inadvertent time, they that have been developed very well will quietly come to us and bring us more needed security and trust.
