PACS Overview
- Physical access control systems (PACS) monitor and secure physical spaces, much like logical access control systems manage digital identities.
- PACS authenticate, authorize, and audit access, often using cards, mobile phones, or biometrics.
Authentication, Authorization, and Control Points
- Authentication verifies identity, while authorization determines access privileges.
- Control points are physical devices, like door strikes or gates, controlled by the PACS.
PACS Components
- PACS components include credentials, readers, access control panels, and host software.
- Panels store access rules and control physical access points, often with backup power.
