Understanding Access Control Systems
Access control systems are designed to provide a multi-layered approach to security by combining various components, such as:
Credentials: These are the means by which individuals identify themselves to gain access, such as key cards, fobs, biometrics (e.g., fingerprints, facial recognition), or mobile credentials.
Readers: These devices are responsible for reading and authenticating the presented credentials, typically installed at entry points or access points.
Controllers: Acting as the brain of the system, controllers process the data received from readers and manage the access decisions based on predefined rules and permissions.
Access Points: These are the physical barriers, such as doors, gates, or turnstiles, that are controlled by the access control system, allowing or denying entry based on the authenticated credentials.
Software: Access control software provides the interface for managing and monitoring the system, configuring user permissions, generating reports, and integrating with other security systems.
Types of Access Control Systems
