Enterprise-class, feature-rich S2 access control systems integrate credential-based access control, intrusion detection and video security applications for a unified management and administration experience. 100% web based, these IP networked systems require no software installation or client license fees. Flexible system architecture allows for a range of applications from single sites to globally distributed physical security management systems. S2 building access control systems also integrate with legacy access control systems, allowing for easy upgrades.

Our flagship access control product, S2 NetBox, was an industry first with its solid-state design, browser-delivered system management, intuitive user interface and ability to integrate with other best-of-breed manufacturers. The entire S2 access control product line continually benefits from our commitment to innovation, with over 20 software versions released since 2004.

S2 IP access control system architecture maintains a complete database on an S2 Network Controller and distributes the data to S2 Network Nodes (portals) supporting one or two readers, assuring that the access control capabilities function during network outages.
