What is access control? What are the types of common access control systems at present? What are their advantages and disadvantages?
- Password access control system,
- card access control system,
- the biometric access control system
Password Access Control SystemThrough the input of the password, the system judges the correct password on the drive electric lock opens the door release. Advantage: just remember the password, no other media. Lowest cost. Disadvantages: slow speed, it usually takes several seconds to enter the password, if there are too many people in and out, you need to queue up. If you enter something wrong, you have to re-enter it, which takes longer. The security is poor, the person nearby is easy to remember the password of others by the gesture, the password is easy to forget or leak. Trend: password access control is used less and less, only in the low-security requirements, low cost, infrequent use of the occasion is still in use, for example, the safe.
Swipe Card Access Control SystemAccording to the type of the card is divided into contact card access control system (magnetic stripe card bar code card) and contactless card (also known as induction card, RF card) access control system. Contact card entrance guard system but due to the contact card is easy to wear and use, the card is easy to damage, etc., the scope of use has less and less, only in and bank CARDS, magnetic stripe CARDS) on occasion be used, for example, bank VIP channel entrance guard system, unattended ATM entrance guard system, and other areas of the local industry are still in use. Contactless IC card, due to its durability and cost performance, fast reading speed, the high-security advantage is the mainstream of the current access control system. So, at present, a lot of people will be a contactless IC card access control system referred to as the access control system.
Biometric Access Control SystemAn access control system that identifies people according to their biological characteristics. Common systems are fingerprint entrance guard system (each person's fingerprint texture features exist differences), palm instrument entrance guard system (everyone's hand bone shape differences) iris entrance guard system (each person's retina by optical scanning dissimilarity) as recognition entrance guard system (everyone's different features and location), etc. The advantages of biometric access control systems are: no need to carry CARDS and other media, the probability of repetition is small, not easy to be copied, high security. The downside: high cost. Because biometrics needs to compare many parameter characteristics, the comparison speed is slow, which is not conducive to the occasion with too many people. Biological characteristics of the human body will change along with the environment and the change of time, so prone to false reject rate (it is the man, but his biological characteristics have changed), for example, fingerprint varies because of the season and the dry humidity, palm change due to the growth of the age and the portrait, iris change due to eye disease, etc. Therefore, although the biometric access control system is advanced and safe, its application scope is limited, and it is only applied in a few fields with a small number of people, high-security requirements, and high cost. It is not the mainstream of the current access control system.
Most other existing access control and time attendance systems have a centralized operation system that requires an access controller that is installed at the door to be connected to a controller, and they tend to have complicated wiring structure.
Chiyu's access control solutions provide a variety of biometric and proximity verification access controllers installed at doors, functioning as its own intelligent controller, thereby providing better flexibility and security. In addition, the extension unit Secure I/O installed inside the door so that users can have an added security only a detachable structure can offer. Chiyu Technology provides users a variety of access controllers with different verification types such as biometric, RFID, facial recognition, and finger vein.
