Advantages and disadvantages of access control machine

Compared with the networked access control system with separate card reader and controller, the cost of access control machine is lower, but because the control part is exposed and the security level is slightly lower, it is often used for users with only one access point in some companies. Most large and medium-sized multi-door access control systems will adopt networked access control system with card reader and controller separated to meet the stability and security requirements of middle and high-end access control users.

Access control machines are often equipped with keyboard settings and LCD display, which can meet the appearance requirements of some domestic customers. However, because LCD is a fragile accessory, its stability and anti-interference will not be as good as the networked access control products with separated card reader and controller. Imported products (except some products from Taiwan Province Province) generally adopt the mode of separating card reader and controller.
