The Uniview NVR516 Series is a 16-bay rack-mount network video recorder offered in two channel counts: NVR516-64 (64-ch) and NVR516-128 (128-ch). Both record cameras up to 12MP with Ultra 265 / H.265 / H.264 compression, output independently over two HDMI ports plus VGA, and support hot-swap RAID 0/1/5/6/10/50/60 across 16 SATA bays holding up to 16 TB each. The recorder also runs extensive on-camera VCA analytics — face detection and comparison, vehicle detection, intrusion and line-crossing detection, temperature/fire detection and people counting — with a 38-language local interface.
Is this the right recorder for you?
Plain-language guide for buyers and installers — based only on what this recorder actually does.
- 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
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.
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.
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.
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.
