Keri Systems KB-4D-SRTR-KIT Borealis KB Cloud Access Controller 4-Door Starter Kit

Simplify cloud-hosted access control and strengthen site security with the Keri Systems Borealis KB Cloud Access Controller 4-Door Starter Kit. This access control panel kit delivers a turnkey solution for facilities that need reliable, low-latency decision-making and centralized monitoring without heavy network overhead. The 4-door controller includes on-board TCP/IP connectivity—no additional network adapters required—and supports up to 10,000 cardholders and a 10,000-event buffer to meet demanding enterprise needs.

Designed for installers and IT teams, the Borealis KB minimizes bandwidth use by making intelligent local access decisions while securely syncing configuration and logs to the cloud. Easy commissioning with QR-code enrollment and an embedded MAC address speeds deployment across LAN/WAN networks. Expandability via RS-485 trunks allows installation of NXT-4x4 I/O boards to add inputs/outputs as projects grow. Housed in a locking metal enclosure with quick-disconnect connectors, it provides a durable foundation for security, surveillance, and access monitoring across commercial, education, and healthcare sites.
