The Uniview NVR301-S3-P Series is a 1-HDD PoE network video recorder offered in two sizes: NVR301-04S3-P4 (4-ch, 4 built-in PoE ports) and NVR301-08S3-P8 (8-ch, 8 built-in PoE ports). Both record cameras up to 8MP with Ultra 265 / H.265 / H.264 compression and output simultaneously over 4K HDMI and VGA. One SATA bay takes a hard disk up to 10 TB; the local interface is available in 21 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.
- A second hard disk or RAID — this series has a single SATA bay
- Gigabit uplink — the network port is 10/100M
- Alarm in/out wiring for sirens or sensors — this series has no physical alarm terminals
- Audio input — it has an RCA audio output only (camera-side mics still record)
- High-power PoE devices beyond budget — each port is capped at 30 W, and total PoE budget is 54 W (04S3-P4) or 75 W (08S3-P8)
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.
Saves your disk. Catches what matters.
Two real capabilities from the datasheet that matter every day: storage efficiency and smart detection.
Half the storage, same image
Ultra 265 compression cuts recording size dramatically versus H.264 — on the same 10 TB disk you keep footage for weeks longer, or record more cameras at higher resolution.
Catches intrusions, not just motion
Built-in Face Detection plus SIP smart rules (Intrusion Detection, Cross Line Detection, Enter/Leave Area) and Ultra Motion Detection on up to 4 channels — backed by Face Snapshot Search and Behavior Search to jump straight to the right clip.
