Access Monitoring System

SENTINEL™ AXS is designed to detect open and close events at critical access points—such as lock boxes, maintenance holes, handholes, and other enclosures—where a verified open or closed state is essential for security and compliance.
Leveraging next-generation technology, SENTINEL AXS reduces both cost and complexity. Its universal, plug-and-play sensors can be deployed virtually anywhere without the need for customized hardware. The system uses passive sensors, requiring no power in the field, which enhances reliability and simplifies installation—especially in remote or difficult-to-access locations.
Fully integrated with INSIGHT™ software, SENTINEL AXS delivers centralized visibility, real-time alerting, and automated event logging to streamline monitoring and response. It supports single-mode fiber and is available in 1-, 2-, and 4-port models, allowing for scalable deployment across small or large infrastructure environments.
Whether you're upgrading an existing Alarmed PDS or implementing a new secure infrastructure, SENTINEL AXS ensures reliable monitoring of access points across any environment—including manholes and handholes spread over long distances. With its scalable architecture and field-proven fiber optic technology, SENTINEL AXS delivers dependable coverage, event tracking, and rapid response across the full span of your network.
