The Uniview NVR301-B-P-IQ Series is a 1-HDD PoE network video recorder offered in two sizes: NVR301-04B-P4-IQ (4-ch, 4-port PoE) and NVR301-08B-P8-IQ (8-ch, 8-port PoE). Both record cameras up to 12MP with Ultra 265 / H.265 / H.264 compression, output simultaneously over 4K HDMI and VGA, and include built-in Face Detection, Face Comparison and AcuSearch / AcuTrack smart search. One SATA bay takes a hard disk up to 24 TB; 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.
- Gigabit network uplink — the built-in network port is 10/100M (matched to this series' 80 Mbps bandwidth)
- A second hard disk or RAID — this series has a single SATA bay
- Serial PTZ control from the NVR itself — RS485 and RS232 are both listed N/A on this series
- Physical alarm input/output terminals — Alarm In and Alarm Out are both N/A on the rear panel
- Extra PoE budget for high-draw cameras — each port is capped at 30 W (standard PoE/PoE+, not PoE++ 60W+ devices)
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.
Cameras plug in. AI finds the moment.
Two real capabilities that define this series: built-in PoE and onboard AI search.
No separate PoE switch to buy
Each RJ45 port is independent PoE — up to 30 W per port, 50 W total on the 04B-P4-IQ or 75 W total on the 08B-P8-IQ (IEEE 802.3at/af) — plug cameras straight into the recorder.
Find the moment, not the footage
Built-in Face Detection, Face Comparison and Vehicle Detection (LPR) 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.
