16 / 32 / 64-channel 2U rack-mount network video recorder — 8 SATA bays with RAID 1/5, records cameras up to 16MP, Ultra 265 compression, ONVIF certified for third-party IP cameras.
Sample quantities are welcome — testing one or two units first is the normal way to start.
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.
Plain-language guide for buyers and installers — based only on what this recorder actually does.
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.
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.
Complete list from the official datasheet.
Two real capabilities from the datasheet that matter on large sites: disk-failure protection and fast multi-channel search.
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.
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.
