The Uniview NVR301-S3 Series is a 1-HDD network video recorder offered in three sizes: NVR301-04S3 (4-ch), NVR301-08S3 (8-ch) and NVR301-16S3 (16-ch). All three record cameras up to 8MP with Ultra 265 / H.265 / H.264 compression, output simultaneously over 4K HDMI and VGA, and carry ONVIF certification. 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.
- PoE ports — cameras need a separate PoE switch (we bundle one at combo price)
- A second hard disk or RAID — this series has a single SATA bay
- Gigabit uplink — the network port is 10/100M (fine for 16 cameras at 64 Mbps total)
- Alarm in/out wiring for sirens or sensors
- Audio input — it has a 3.5mm audio output only (camera-side mics still record)
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. Finds the moment.
Two real capabilities from the datasheet that matter every day: storage efficiency and fast retrieval.
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.
Find the moment, not the footage
Built-in face detection on up to 4 channels feeds Face Snapshot Search and Behavior Search — the recorder indexes up to 2 million face snapshots so you jump straight to the clip you need instead of scrubbing hours of footage.
