Product information summary

About the product
This Uniview 256 Channel NVR with 24x SATA Bays is designed for large-scale installs with demanding hardware requirements. High-speed miniSAS interfaces for rapid data transfers make the Uniview 256-channel NVR the ideal solution for 24/7 archival recording sites from hundreds of different devices.
Supports up to 256 individual IP devices, including generic ONVIF cameras in a variety of conformance profiles (including Profile S, G, C, Q, A and T), as well as hot swap functionality with RAID 0, 1, 5, 6, 10, 50 and 60 storage schemes for maximizing storage or for on-site redundancy. N+1 Hot Spare ensures recordings are automatically backed up to secondary drives in the event of a drive failure—ideal for high-security installs.
Supports 2-channel HDMI and 1-channel VGA out. HDMI supports up to 4K (3840 x 2160p) resolution output.
ANR technology and redundant power supply options ensure 100% uptime and admin alerting on network, power or storage failures. Supports major Uniview camera smart features, including facial detection, human/vehicles detection, temperature detection, people/traffic counting and metadata, and more.
