The Uniview NVR504-E-IQ Series is a 4-HDD network video recorder offered in three sizes: NVR504-16E-IQ (16-ch), NVR504-32E-IQ (32-ch) and NVR504-64E-IQ (64-ch). All three record cameras up to 32MP with Ultra 265 / H.265 / H.264 compression, support RAID 0, RAID 1 and RAID 5 with Disk Group and Redundant Storage across four independent SATA bays (up to 24 TB each), and include built-in Face Detection, Vehicle Detection (LPR), Temperature Detection and AcuSearch / AcuTrack smart search. Two independent HDMI/VGA output pairs (HDMI1+VGA1 and HDMI2+VGA2) run at the same time, and the local interface is available in 38 languages including Spanish (Latin America), Portuguese (Brazil) and French.
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 fifth hard disk or more — this series tops out at 4 SATA bays (up to 96 TB total with four 24 TB drives)
- RAID 6 or RAID 10 — the Disk Array Type on this series supports RAID 0, 1 and 5 only
- A single unified 4-way display — HDMI1/VGA1 and HDMI2/VGA2 are two independent output pairs, not four synced views of one layout
- DC-only power sites — this recorder runs on AC 100–240V mains, with no DC input option
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.
Four bays, RAID protected. AI finds the moment.
Two real capabilities that define this series: RAID-protected multi-bay storage and onboard AI search.
Room to grow, protected against drive failure
Four independent SATA bays each take a disk up to 24 TB — up to 96 TB in one recorder, with Disk Group and Redundant Storage supporting RAID 0, 1 or 5 so a single drive failure doesn't stop recording.
Find the moment, not the footage
Built-in Face Detection, Vehicle Detection (LPR) and Temperature Detection on the camera side feed AcuSearch, AcuTrack, Face Snapshot Search and Human Body Search on the recorder — narrow hours of footage down to the exact clip across up to 64 channels.
