NVR824-128R / 256R

Name: Uniview NVR824-128R / 256R
Brand: Uniview

128 / 256-channel network video recorder — 24 hot-swap SATA bays with RAID 0/1/5/6/10/50/60, two independent 4K HDMI outputs plus VGA, records cameras up to 12MP, with 768 Mbps incoming bandwidth and an optional redundant power supply.

CHOOSE YOUR SIZE — TWO MODELS ON THIS PAGE

Rule of thumb: count your cameras across the whole deployment, then leave room to grow — 128 channels covers a large single site; step up to the 256R for a multi-building campus or a central monitoring room aggregating several sites. Highlighted rows in the spec table below show every difference between the two.

Is this the right recorder for you?

Plain-language guide for buyers and installers — based only on what this recorder actually does.

Large campuses & enterprise sites128 or 256 channels in one recorder covers a major site or aggregates several buildings without stacking multiple recorders.

Storage that can't afford to fail24 hot-swap SATA bays with RAID 0/1/5/6/10/50/60 and N+1 hot spare protect footage — a failed disk swaps out live, without taking the recorder offline.

Long-term evidence at scale24 bays up to 24 TB each (up to 576 TB total), plus two miniSAS ports to add an external disk enclosure when you outgrow the internal bays.

Video walls & control roomsTwo independent HDMI outputs (4K each) plus VGA, and optional 4-ch/7-ch HDMI decoding cards in the four rear extension slots, drive multiple large-format displays from one unit.

Redundant power for critical sitesAn optional second power supply (PWR-DC12-550A-IN, 550W) keeps recording through a single PSU failure — order it alongside the recorder for sites that can't go dark.

City-scale vehicle & face searchVCA Search covers face snapshot, face comparison, motor and non-motor vehicle, human body and general search, plus a vehicle picture library for up to 25,000 vehicle images across 5 libraries.

Not the right pick if you need…

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.

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.

HOT-SWAP STORAGE

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.

SMART SEARCH AT SCALE

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.
