The difference between an access controller and an access control machine. Does the access controlle

The access controller is a circuit board with many binding posts, which are similar to the motherboard of a computer, and need to be connected to other devices before it can be used and operated. It's like a computer motherboard, you need to connect the graphics card to what memory, the access control machine. It includes the access control controller, but generally the single-door access control controller only controls one door, and the access control controller has 4 or more doors.

The access control machine can read the card and enter the password directly on the machine. Access controllers generally require a card to be registered via a computer. The following diagram is an access control system composed of access control machines.

Access control machine is a vague concept in language expression. This appellation is for access control systems.

Or a general term for the phenomenon of access control all-in-one machine and access control card reader.

To figure out the name, first have to judge who is using the word.

1. The user is Party A.

Or the tendering party is generally unprofessional, can not understand the various structures of access control is very professional, therefore, the general name of the access control equipment is "access control machine", "credit card machine", "magnetic card door", etc.;

Second, the supplier The supplier is generally a more professional company, but the first order.

Vague words such as "access control machine" are often deliberately used in the interior. What is the purpose? (1) I am afraid that too professional customers will not understand, so the title is simplified; (2) Deliberately creating vague concepts to make customers hallucinate... Thus, it is impossible to judge the specific value of this product;

3. Other ** that do not need to refine the name include security magazines, perception magazines, etc., because they do not need to be detailed.

Therefore, in a sense, the access control machine contains the access control component.

Hello dear and happy to answer your <>

The difference between the access control module and the access control controller is as follows: the access control controller is the main equipment indispensable in the access control system, which is mainly responsible for the input, output, storage and all the work of the mobile phone of the information data of the entire access control system, and is an important core data processing and storage part of the access control system. The access control controller is composed of a plurality of module units, which is the core of the whole system is the control unit, and the core of the control unit is that the controller is responsible for data processing and storage, and decodes and authenticates the information transmitted by the face, ***, and card swiping transmitted by the reading head, which is equivalent to the soul and heart of the access control system.

The access control module, also known as the entrance and exit control system, is an intelligent control system for the entry and exit of management personnel and goods. Common access control systems are: access control systems that use password authentication to pass, access control systems that use contactless IC card authentication, fingerprints, iris, palm shapes, and fingers.

The access control system can be divided into two categories: non-networked access control system and networked access control system, wherein non-networked access control system equipment includes access control power supply, access control host, door opening button or exit card reader, electric lock; Networked access control system equipment includes access control host, door opening button or exit card reader, card reader, electric lock, communication converter, computer host, access control power supply, professional access control management software.

Access Control System Application Requirements:

1. Reliability.

Access control systems are designed to prevent losses and crimes, so they must be extremely reliable. An access control system may not have an alarm during most of its operation, so the probability of an alarm that needs to be reported is very small, but if the alarm system fails within this very small probability, it often means that disaster has come. Therefore, in all stages of design, construction and use of access control and security systems, we must implement reliability design and reliability management to ensure the high reliability of products and systems.

2. Certification. In addition, in the design of the system, equipment selection, commissioning, installation and other aspects are strictly implemented in the relevant national or industry standards, as well as the requirements of the public security department on safety technology prevention, the product must go through a number of certifications, and has a large number of typical users, many years of normal operation.

3. Security.

The high safety mentioned here refers to the natural or quasi-natural attributes of the product or system, which should ensure the safety of the operation of the equipment and the system, and the safety of the operator, for example: the equipment and the system itself should be able to prevent high temperature, low temperature, warm heat, rain, and can prevent radiation, electromagnetic interference, drop, etc.; On the other hand, the access control and security lead delay system should also have the function of preventing vandalism, such as: anti-vandalism protective shell, anti-demolition alarm, anti-short circuit, etc.

4. Functionality.

The application of access control system is not limited to a single entrance and exit control, but also requires it to be applied not only to access control, attendance management, security alarm, parking lot control, elevator control, building automation, etc., but also to control a variety of control functions with other systems.
