The document discusses three access control systems: 1) AxiomV Enterprise Edition, which integrates access control, alarm monitoring, and video surveillance into a building management and security system with a multi-server architecture and fail-over capabilities. 2) Integra32 Security Management System, which seamlessly integrates access control, intrusion alarms, elevator control, CCTV, biometric authentication and other systems through a .NET architecture designed for Windows. 3) IRC-2000 controllers, which allow control of two access control points and utilize flash firmware with fully distributed intelligence to make access decisions off-line without a computer.
