Brand: Uniview

64 / 128-channel network video recorder — 16 hot-swap SATA bays with RAID 0/1/5/6/10/50/60, independent dual-HDMI plus VGA output, records cameras up to 12MP, with 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 — 64 channels covers most single large facilities; step up to the 128-ch if you're combining several buildings or a city-scale project. 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 & city-scale projects64 or 128 channels in one 3U box covers a large campus, industrial park or city-surveillance hub without stacking multiple recorders.

Storage that can't afford to fail16 hot-swap SATA bays with RAID 0/1/5/6/10/50/60 protect the footage — swap a failed disk while the recorder keeps running.

Long-term evidence retention at scale16 SATA bays, up to 16 TB each (up to 256 TB total), keep months of high-resolution footage online across a large camera count.

High camera counts on one network link384/512 Mbps incoming bandwidth over four Gigabit ports plus two SFP uplinks handles 64 or 128 higher-resolution streams without choking the network.

Independent multi-screen monitoringHDMI1, HDMI2 and VGA independent outputs let a control room show three different views at once — not just a mirrored screen.

Power resilienceRedundant power supply is available as an option, and Support N+1 Hot spare keeps recording after a single disk fails without waiting for a technician.

Deep VCA analytics & fast searchFace detection/comparison, vehicle detection, intrusion detection, temperature/fire detection and people counting run on the cameras; the recorder's VCA Search narrows a 64- or 128-channel deployment down to the exact clip.

Not the right pick if you need…

PoE ports — cameras need a separate PoE switch (this recorder has no built-in PoE ports)
A second power supply included out of the box — the Power Supply 2 slot is present but the AC power module is an optional accessory (PWR-300A-IN), sold separately
Compact or desktop placement — this is a 3U rack chassis (482 × 477 × 131 mm, ≤10 kg without HDDs) that needs a server rack, not a desk or shelf
A small or single-site deployment — 16-bay, 64/128-channel scale is built for large multi-building or city-level projects, not a shop with a handful of cameras
Built-in decoding cards out of the box — Decoding Card 1/2 slots exist on the rear panel but the cards themselves are optional add-ins, not included

16-bay RAID storage. Deep VCA analytics.

Two real capabilities that define this series: hot-swap RAID across 16 bays, and extensive camera-side VCA analytics with recorder-side search.

RAID 0/1/5/6/10/50/60

16 bays, hot-swap, and a disk can fail safely

16 independent SATA bays each take a disk up to 16 TB (up to 256 TB total) and support hot swap plus RAID 0/1/5/6/10/50/60 — mirroring or parity protection, and Support N+1 Hot spare keeps recording after a single drive failure without waiting for a technician.

SMART VCA

Face, vehicle and intrusion detection, built in

Face Detection, Face Comparison, Vehicle Detection, intrusion/line-crossing detection (SIP), Ultra Motion Detection, temperature and fire detection, and people counting run on up to 32 images/s across all channels, feeding VCA Search — Face Snapshot, Face Comparison, Motor/Non-Motor Vehicle, Human Body and General Search — so operators jump straight to the clip instead of scrubbing 64 or 128 channels of footage.
