Description: A remote access control system is a technological solution that allows managing and restricting access to physical or digital spaces from a distant location. These systems use embedded components, such as microcontrollers and communication modules, to authenticate users and grant or deny access based on predefined credentials. The main feature of these systems is their ability to operate autonomously and connect to networks, enabling administrators to monitor and control access in real-time. Additionally, they often include functionalities such as event logging, security alerts, and the ability to integrate multiple authentication methods, such as RFID cards, biometrics, or passwords. The relevance of remote access control systems lies in their ability to enhance security and resource management in various environments, providing a level of control that is difficult to achieve with traditional methods. These systems are particularly useful in situations where security is critical, such as in government facilities, data centers, and commercial buildings, where access must be carefully regulated and monitored.
