Advantages and disadvantages of seven types of gate lock
1. Non-network access control: one host corresponds to control and management of one door, which is directly controlled by controller and cannot be controlled by computer software. Advantages: low cost, ease of installation and maintenance. Cons: No entry and exit records. Scope of application: not suitable for places where number of doors is more than 5 sets, number of people is more than 50, or flow of personnel is large, and personnel enter and exit frequently.
2. 485 network access control: direct use of computer software for management and control, including card and event management. This access control can communicate with a computer. Advantages: centralized control, convenient management, viewing of records, analysis and processing of records for other purposes. Training is simple and additional services such as attendance can be provided. Disadvantages: high price, complexity of installation and maintenance. Scope of application: suitable for rooms with a large number of doors, a large number of people and a frequent flow of people.
3. TCP/IP Access Control: Also known as Ethernet Network Access Control, this is an access control system that can be networked by connecting computer and controller to network via a network cable. Advantages: In addition to all advantages of 485 network access control, it also has advantages of faster speed, easier installation, more networks, and inter-regional or long-distance network. Disadvantages: high price, requires professional network knowledge. Scope of application: Suitable for installation in large projects, with a large number of people, speed requirements, and inter-regional projects.
4. Fingerprint access control system: access control is done by fingerprint, not by card. Benefits: It has same features as Network Access Control 485, but with a higher level of security. Disadvantages: Fewer people can be controlled, and passing speed is slow.
5. Card access control system: According to type of card, it is divided into contact card access control system (magstripe bar code card) and contactless card (also called RF contactless card) access control system. barrier-free channel machine.
The contact card access control system is used less and less because contact card is easy to carry, frequency of use is low, and card is easy to damage. It is only used in cases related to bank cards (magstripe cards) Uses such as: bank VIP channel access control system, ATM unattended access control system and other local industries are still in use. Contactless IC cards, due to their durability, good economic performance, high reading speed and high securitysecurity, are main focus of modern access control system. Therefore, at present, many people simply call contactless access control system with IC card an access control system.
6. Password access control system: When you enter a password, system determines that password is correct, and then actuates electric lock to open door and release.
Benefits: Just remember password, no need to carry other media with you. The lowest cost.
Disadvantages: slow speed, it usually takes a few seconds to enter password, if there are too many people in and out, you have to queue. If you make a mistake, you need to re-login, which takes longer. Security is poor, people around you easily remember other people's passwords by gestures, and passwords are easy to forget or leak. Trend: There are fewer and fewer cases where password access control is used, and it is used only in cases with low security requirements, low cost and infrequent use. Example: secure.
7. Biometric Access Control System: An access control system that identifies a person based on various biological characteristics of human body.
The usual ones are: fingerprint access control system (the texture of fingerprint is different for everyone), palm-type device access control system (the shape of palm bone is different for everyone), iris access control system (the retina is scanned optically for everyone. There are differences) a portrait access control system with recognition (facial features and position are different for everyone), etc. The advantages of a biometric access control system: no need to carry cards and other media with you, less likelihood of duplication, copying complexity and high security. The disadvantage is: high cost. Since biometric identification requires comparison of many parameters and features, comparison speed is low, which does not contribute to cases with a large number of people.
