A Door Controller is a central hardware component of an access control system that regulates and monitors entry through secured doors. It connects with devices such as RFID card readers, biometric scanners, keypads, electric locks, exit buttons, and alarm systems to manage authentication and door operations.
When a user presents valid credentials—such as a card, fingerprint, PIN, or facial recognition—the door controller verifies the information and grants or denies access accordingly. It also records entry and exit logs for monitoring and reporting purposes. Many modern door controllers support multi-door management, real-time monitoring, cloud connectivity, time-based access scheduling, and integration with CCTV and building management systems.
Door Controllers are widely used in offices, factories, data centers, schools, hospitals, and commercial buildings. By providing centralized control, enhanced security, and detailed activity tracking, they play a vital role in modern access management solutions.
