What is the Access control machine?
The so-called access control all-in-one machine is an access control product that integrates a card reader and a controller. There are independent and internet ones. Lower cost compared to internet access control system where card reader and controller are separated. However, because the control part is exposed and the security level is slightly lower, it is usually used for users who have only one access control point in some companies.
Most medium and large multi-access control systems will use network access control systems with separate readers and controllers to meet the needs of medium-sized and large-scale multi-access control systems. The stability and security needs of high-end access control users.
The All-in-one machine is usually equipped with a keyboard setting and an LCD display, which can meet the appearance requirements of some domestic customers. However, since the LCD is a vulnerable part, its stability and anti-interference are not as good as the Internet access control products in which the card reader and the controller are separated. Imported products (except for some Taiwanese products) usually adopt the separation method of card reader and controller.
Through the computer host is an input device that is analyzed and judged by the computer host (the motherboard CPU. Memory and hard disk are used for memory) to judge, and then display the printer through the speaker to respond and output, and also complete the intelligent behavior. Through network cards and protocols, computers form a computer network.
The same is true for the access control all-in-one machine.
The Card reader and the button door magnetic signal are composed of the card reader and the button door magnetic signal. The signal is sent to the controller. The CPU and memory on the controller analyze, compare and store, and then open the door through the electric lock action of the output device, and alarm through the alarm prompt.
Through the 485 communication converter TCP/IP communication equipment protocol, just like human language, a network is carried out and an access control group is formed.
