The Uniview NVR824-R Series is a 24-HDD rack-mount network video recorder offered in two sizes: NVR824-128R (128-ch) and NVR824-256R (256-ch). Both record cameras up to 12MP with Ultra 265 / H.265 / H.264 compression, output independently over two HDMI ports (each up to 4K) plus one VGA port, and support hot-swappable SATA bays with RAID 0/1/5/6/10/50/60 and an optional second power supply for redundancy. Each of the 24 SATA bays takes a hard disk up to 24 TB, two miniSAS ports allow expansion to an external disk enclosure, and the local interface is available in 38 languages including Spanish (Latin America), Portuguese (Brazil) and French.
Is this the right recorder for you?
Plain-language guide for buyers and installers — based only on what this recorder actually does.
- A compact desktop unit — this is a large rack-mount chassis (484.6 × 533 × 175.5mm, about 12.5kg without HDDs), not a desktop recorder
- Built-in PoE ports — cameras need a separate PoE switch
- A second power supply included as standard — the redundant PSU (PWR-DC12-550A-IN) is an optional add-on, not included
- A small deployment — this series starts at 128 channels; a lower-channel Uniview NVR fits smaller sites better
- Full per-channel NVR-side smart analytics specs in this document — the detailed Smart-by-NVR feature and channel-count breakdown is published in a separate Smart Card datasheet, not in this general specification
Worried about counterfeits? Order under your own company name.
For corporate buyers: we support submitting the purchase order to Uniview under your company's real name — your company appears on the official order, so the origin of the goods can be verified directly with the manufacturer. Just provide your company name and pay by corporate bank transfer. Models carrying the anti-counterfeit label can also be self-verified on Uniview's official Anti-Counterfeiting Query page — enter the unit's SN plus the scratch-off code.
Using your own freight forwarder? No problem.
For small and mid-size orders, we deliver directly to your designated forwarder's warehouse in China (EXW / FOB Guangzhou). From hand-over onward, international shipping and destination-side arrangements are handled by your forwarder — the way you already work.
Key Features
Complete list from the official datasheet.
Twenty-four bays. Seven RAID levels. Zero downtime.
Two real capabilities from the datasheet that matter most on large, mission-critical sites: hot-swap storage redundancy and city-scale smart search.
24 bays, seven RAID levels, one live swap
24 hot-swap SATA bays with RAID 0/1/5/6/10/50/60 and N+1 hot spare — replace a failed disk without powering down, and expand further with two miniSAS ports to an external disk enclosure.
Find one face or one vehicle across 256 channels
VCA Search indexes face snapshots, face comparisons, motor and non-motor vehicles, human bodies and general search — combined with a vehicle picture library holding up to 25,000 images across 5 libraries, so investigators jump straight to the match instead of scrubbing footage channel by channel.
