People's security awareness is gradually improving, and the access control system is gradually becoming intelligent. Compared with security methods such as monitoring and alarming, the access control system is passive to active, and the hidden dangers are directly excluded from the control channel. How should people choose an intelligent access control system?
According to different application fields, the requirements in terms of security and applicability are different, and the access control system is classified according to the needs and development:
1. According to the different identification methods, it is divided into: password identification, credit card identification, biometric identification, two-dimensional code identification
1. Password identification
It is to identify and verify the entry and exit authority by entering the password is correct. Disadvantages: The password is easily leaked or forgotten, and the sensitivity of the keys is reduced after prolonged use.
2. Card identification
The access authority is identified through the card reader or card reading encryption. The card is divided into magnetic card and radio frequency card. ① The magnetic card has low cost, one person and one card can be connected to the computer, and there is a door opening record. The disadvantage is that the card equipment will be worn, and the card is easy to If it is copied, the card is also invalid due to the external magnetic field. ② UHF card, the card device does not need to be contacted and does not open the door. It is simple and convenient. There is a record of opening the door.
It is to identify the entry and exit authority by detecting the biometric features of the personnel, such as fingerprint recognition, face recognition, etc., with high security, no need to carry cards or remember passwords, the disadvantage is high cost, and has requirements for the use environment.
4. QR code identification
It is to register and log in through the mobile APP or applet to generate a QR code to identify the access authority.
2. According to the design principle, it is divided into an integrated access control machine and an access control controller (with its own reading head) (separate from the card reader)
1. All-in-one access control machine
It is a device that integrates display screen, key swipe card recognition, and biometric recognition.
2. Access controller
The controller comes with a card reader. The access controller must be installed outside the door. The controller is separated from the card reader. Only the line of the card reader is outside the door, and other control lines are inside the door. The card reader transmits digital signals. , if no one can enter the door with an invalid card or password,
Three, according to the communication method is divided into
1. Unconnected access control
3. TCP/IP network access control
