Classification of access control system

Abstract: With the rapid development of social science, technology and socioeconomic and social economy, information security, property security, and personal security are now more valued. So the safety and safety of the residential area
The humanization requirements of access control are getting higher and higher, the traditional [] ban system is constantly upgrading, and the smart [] forbidden system is now widely used. So, what is the working principle of the access control system?

What are the functions of the system? How to set the access control system? Let's take a look at the relevant knowledge of the forbidden system together.

Classification of a access control system
1. Swipe card 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 non -contact card (also known as sensor card, radio frequency card) access control system, contact card access control system
Because the cards that are in contact are easy to wear, the number of uses is not large, the card is easy to damage, etc. The range of use has become less and less.
The occasion of the level is used, and the non -contact IC card. Because of its advantages such as good durability and cost performance, fast reading speed, and high security, it is the mainstream of the current gate.
2. Password access control system
By entering the password, the system judge the password correctly, drive the electric lock, open the door to release, the password door] As long as the password is remembered, no other media is required, the cost is the most cost
Low, but this kind of access control system is slow, and the input password generally takes several seconds. If there are too many people entering and leaving, you need to line up. If you enter an error, you need to re -enter
It takes longer and has poor security. The people next to it are easy to remember the passwords of others through gestures, and the password is easy to forget or leak.
3. Biometric access control system
The access control system that recognizes the identity according to the different biological characteristics of the human body, common ones are: fingerprint access control system (the characteristics of each person's fingerprint lines are different), palm type
The controller control system (the bone shape of each person's palm is different), the iris door] prohibited system (each person's retina is different through optical scanning), face recognition
Mengchu system (each person's facial features and positions are different).
Biological identification doors] The prohibited system does not need to carry cards such as cards. Repeated banknotes are not easy to be copied, and safety is high, but this door] The cost of the prohibition system is high, and the comparison speed is compared with
Slowness is not conducive to too many people. Therefore, although the biological identification access control system is advanced and safe, the scope of application is limited, only in the number of people, and the safety requirements
High, do not worry about the application of a few areas such as high costs, not the mainstream of the current i] forbidden system.
