Access Controller Overview The traditional mechanical door lock is just a simple mechanical device. No matter how reasonable the structural design and how strong the material is, people can always open it by various means. The management of the keys in a lot of access (like the office, hotel room) is very troublesome. The key and the replacement of the key must be replaced with the key. In order to solve these problems, electronic magnetic card locks and electronic code locks have emerged. The emergence of these two kinds of locks has improved the management of the entrance and exit channels to a certain extent, and the channel management has entered the electronic age, but with these two types. The continuous application of electronic locks, their own defects are gradually exposed, the problem of magnetic card lock is that information is easy to copy, the card and the card reader have large wear, high failure rate and low safety factor. The problem with the password lock is that the password is easy to leak, and there is no way to check it, and the safety factor is very low. At the same time, most of the products in this period are installed outside the door with the card reading part (password input) and the control part, and it is easy to be opened by the person outdoors. The access control system of this period still stayed in the early immature stage, so the access control system at that time was often called electronic locks, and the application was not extensive.
