Ubiquiti Enterprise NVR Core – 3U Surveillance Recorder for Enterprise Systems
Ubiquiti Enterprise NVR Core (ENVR-Core) is a network recorder designed to centralize and support extensive IP surveillance infrastructures and access control systems in corporate environments. The device's computing foundation is a 128-core ARM v8.2 processor (clocked at 2.6 GHz), supported by 64 GB of RAM. This hardware configuration allows for the smooth management and recording of video streams from up to 300 4K cameras, 400 2K cameras, or as many as 500 Full HD cameras. The recorder natively supports the UniFi Protect and UniFi Access platforms, enabling simultaneous operation of over 300 access controllers (Access Hubs).
The 3U design, designed for mounting in a standard 19" rack, offers 16 built-in bays for HDDs or SSDs in 2.5" and 3.5" formats. The device offers scalable data storage – thanks to the built-in two SFF-8644 expansion ports (with 24G bandwidth), administrators can connect external disk modules, increasing the total system capacity to 48 supported drives. Network connectivity is provided by two high-performance SFP28 interfaces (compatible with 25G/10G/1G standards) and one Gigabit Ethernet RJ45 port.
Power security is ensured by two Redundant 550W power supplies (CRPS standard), supporting hot-swap, allowing for their replacement without interruption to device operation. The housing is made of cold-rolled galvanized steel (SGCC) and certified for compliance with NDAA guidelines confirm the industrial nature of the solution, ready for deployment in high-security facilities.
