The Uniview NVR508-B Series is an 8-bay 2U rack-mount network video recorder offered in three sizes: NVR508-16B (16-ch), NVR508-32B (32-ch) and NVR508-64B (64-ch). All three record cameras up to 16MP with Ultra 265 / H.265 / H.264 compression, support RAID 1/5 across up to 8 SATA bays (24 TB each), and output VGA/HDMI independently, with the 64B model outputting both simultaneously by default. The recorder carries ONVIF certification and provides 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 (we bundle one at combo price)
- Hot-swap drive trays — the manual doesn't describe hot-swap bays; the 8 SATA drives mount inside the chassis
- A redundant/dual power supply — Power Supply is a single AC 100–240V input, not described as dual
- RAID 6 or RAID 10 — Disk Array Type supports only RAID 1 and RAID 5
- RS232 serial control — this series has no RS232 port (RS485 only)
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.
RAID-protected storage. Investigation-ready search.
Two real capabilities from the datasheet that matter on large sites: disk-failure protection and fast multi-channel search.
Protected against drive failure
8 SATA bays (up to 24 TB each) support RAID 1 and RAID 5 with N+1 hot spare — if one disk fails, recordings on the array keep working instead of disappearing with the drive.
Find the moment across 64 channels
Face, vehicle (LPR), human body and general VCA search plus Heat Map and People Counting turn hours of multi-channel footage into the exact clip you need.
