NetBox Extreme

Flexible, scalable system supporting up to 128 portals

The browser-based NetBox™ Extreme access control and event monitoring system supports up to 128 portals. Optional system partitioning allows the entire database to be separated into multiple smaller systems for entities such as field offices or tenants. Features such as person record and cardholder management, event and alarm monitoring, threat level escalation and reporting are accessible from any web browser. There is no software to install.

The solid-state NetBox Extreme appliance is fast and reliable. The system works with existing infrastructure and peripheral devices, making it easy to deploy. Flexible and scalable, the NetBox Extreme system supports up to 64 LenelS2 Nodes. In addition, it tightly integrates with LenelS2 VRx™ and NetVR™ video management systems, providing unified system management and administration. Integration with third-party video management systems is also supported.

The NetBox Extreme system is well suited for mid-scale deployments. As organizations grow, migration to a NetBox Enterprise system is seamless. Large, distributed organizations can centrally manage multiple NetBox controllers with a NetBox Global server, allowing for virtually unlimited scalability.
