Deploy cloud-hosted access control without adding network complexity. The Keri Systems Borealis KB-2D-CTL is a 2-door cloud access controller built for integrators and facilities managers who need a secure, low-bandwidth solution for access control, security, and monitoring. With on-board TCP/IP Ethernet and an embedded MAC address, the KB-2D-CTL connects directly to your LAN/WAN while making routine access decisions locally to conserve bandwidth and maintain reliable operations. The controller supports up to 10,000 cardholders and a 10,000-event buffer for robust auditing and reporting. Expandable via RS-485 trunks, you can add up to two NXT 4x4 I/O boards per trunk to tie into alarms, door sensors, and building automation. Installer-friendly features include QR-code enrollment with the Borealis Connect app, quick-disconnect connectors, and a locking metal enclosure for secure mounting. Ideal for small-to-medium enterprises, multi-site deployments, or integration with surveillance and monitoring systems, the KB-2D-CTL delivers a balanced mix of cloud management and local intelligence. Add this Keri Systems controller to your next access control or security project to simplify provisioning and improve operational uptime.
