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.
Small shops with PoE camerasBuilt-in 4/8-port PoE switch — plug cameras straight into the recorder, no separate PoE switch or extra cabling to buy.
Growing businessesBuy channels you don't use yet: the 08B-P8-IQ lets you add PoE cameras later without replacing the recorder.
Remote viewing on phoneP2P protocol built in — the owner checks the shop from a phone app without a fixed IP or network skills.
Local-language interface38 GUI languages including Spanish (Latin America), Portuguese (Brazil) and French — your customer operates it in their own language.
Longer video retentionUltra 265 roughly halves file size versus H.264 — the same 24 TB disk keeps weeks more footage.
Quick incident lookupBuilt-in Face Detection and Face Comparison feed AcuSearch and Face Snapshot Search — jump straight to the clip you need instead of scrubbing hours of footage.
Not the right pick if you need…
- 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)

Two real capabilities that define this series: built-in PoE and onboard AI search.
PLUG & PLAY POE
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.

Who uses it, where it goes and how to install it
Written for the NVR301-04B-P4-IQ and 08B-P8-IQ from the official datasheet: 4 or 8 IP channels with the same number of built-in PoE ports (50 W or 75 W, 30 W per port), 80 Mbps incoming bandwidth, 1 SATA bay up to 24 TB, 4K HDMI plus VGA.
Which size suits which installation
- NVR301-04B-P4-IQ: shops, kiosks and homes — Up to 4 PoE cameras plugged straight into the recorder, 50 W shared between them, and each camera can use up to 20 Mbps, so 4K or 12 MP cameras record at full quality. The live view splits 1/4.
- NVR301-08B-P8-IQ: restaurants, clinics, offices — 8 PoE ports with 75 W in total for up to 8 fixed cameras, 10 Mbps per channel when all 8 are used, and face detection on up to 8 Uniview face-detection cameras.
- Retail stores using POS and traffic data — POS input on all channels lets cashier transactions be matched to video, and with Uniview smart cameras the recorder produces people counting reports and a heat map.
- Installers handing over to non-technical owners — Plug & Play PoE ports, P2P phone viewing without a fixed IP, and 38 interface languages including Spanish (Latin America), Portuguese (Brazil) and French.
Where and how to install the recorder
- Place it at the centre of the cable runs — Each camera cable goes straight to a PoE port on the recorder, so choose a spot where every run is under 100 m of Cat5e/Cat6 copper. Use solid copper cable, not copper-clad aluminium, so the cameras get full power at the far end.
- Shelf or 1U rack, locked away — The 260 × 222 × 47 mm case sits on a shelf, or in a 19-inch rack with the RM-1U-260 tray. Put it in a locked office or cabinet so the recorder and its disk cannot be taken during a break-in.
- Airflow and temperature — The recorder works from -10 °C to 55 °C, but large disks are rated only for rooms that do not exceed 40 °C, and the PoE ports add up to 75 W of load. Keep the vents clear and avoid hot ceilings, closed metal boxes and direct sun.
- Correct adapter and a UPS — Use the DC 48 V / 1.35 A adapter for the 04B-P4-IQ or DC 52 V / 1.8 A for the 08B-P8-IQ; a 12 V adapter cannot power the PoE ports. The cameras lose power whenever the recorder does, so one small UPS for the recorder and router keeps the whole system recording.
- Disk, LAN and monitor — Fit one 3.5-inch SATA surveillance-grade disk before power-on. Connect the 10/100 Mbps LAN port to the router for phone viewing, and use HDMI (up to 4K) and VGA together if you want a screen at the counter and one in the office.
Planning table: channels, bandwidth, disk and retention
The two sizes share the same 80 Mbps input, single SATA bay, outputs and 30 W per-port limit. The 08B-P8-IQ doubles the channels and ports but its total PoE budget grows only from 50 W to 75 W, so the average power per port is lower; retention also halves when twice as many cameras share one disk.

| Days on 24 TB, all channels at 4 Mbps | 138.9 | 69.4 |
- Pick the 04B-P4-IQ for up to 4 cameras, including 4K, white-light or small PTZ models: 12.5 W per port on average and 20 Mbps per channel.
- Pick the 08B-P8-IQ for 5–8 ordinary fixed cameras; with more than 5 cameras of about 13 W each, power some from their own adapter or a PoE switch.
Camera counts assume 13 W for a camera with strong white light or a small PTZ (a fixed IR camera is typically about 6 W, so all ports can be used); check each camera's real maximum draw. Retention assumes continuous recording at 4 Mbps per camera: days = TB × 10^12 ÷ (cameras × 4,000,000 ÷ 8 × 86,400). The 24 TB maximum applies only if the room stays at or below 40 °C.

4/8 Channel PoE AI NVR FAQ — NVR301-B-P-IQ
How much power can the PoE ports deliver?
Each port is independent PoE at up to 30W (IEEE 802.3at/af). The NVR301-04B-P4-IQ has 4 ports with a 50W total budget and the 08B-P8-IQ has 8 ports with 75W total — cameras plug straight in and get power and video over one network cable, no separate PoE switch needed.
What AI does it run and how do I search recordings?
Face detection, face comparison, vehicle detection (LPR), SIP and UMD run camera-side on all channels, with NVR-side analysis as well. Search tools include AcuSearch, AcuTrack, face snapshot/comparison search, motor and non-motor vehicle search, human body search and search by image.
How many hard drives and what capacity?
One SATA bay, up to 24 TB per surveillance hard drive (usable maximum varies with ambient temperature and disk model). With Ultra 265 compression, a single large disk covers long retention even at 12MP recording — the maximum resolution this recorder supports per channel.
Will third-party cameras still get smart functions?
Partly, yes. The NVR itself analyses normal third-party cameras: face detection on 1 channel at 2MP, SIP on up to 2 channels at 2MP (or 1 at 4MP) and UMD on up to 4 channels at 2MP. For AcuSearch/AcuTrack across all channels, pair it with UNV SIP/UMD cameras.
What monitor and audio connections are on the back?
HDMI up to 4K (3840×2160) at 30 Hz, VGA up to 1920×1080 at 60 Hz, RCA audio in and out for 1-channel two-way audio, one 10/100M RJ45 uplink plus the 4 or 8 PoE camera ports, and USB 2.0 + USB 3.0 for backup to external drives.
How many people can connect remotely?
Up to 128 remote users, sharing 80 Mbps of outgoing bandwidth. Supported protocols include P2P, DDNS, HTTPS, RTSP, SNMP, IPv6 and 802.1x, and browser access works with Chrome 45+, Edge 79+, Firefox 52+ and IE10/11 via plugin. The GUI offers 38 languages.
Can I add a camera through the LAN port when all PoE ports on the NVR301-04B-P4-IQ are used?
No: the limit is the channel count, not the ports. The 04B-P4-IQ records 4 IP channels in total and the 08B-P8-IQ records 8, whether cameras sit on the PoE ports or come in over the LAN. You can mix (for example 3 cameras on PoE and 1 Wi-Fi or remote camera over the LAN), but for a fifth camera you need the 08B-P8-IQ.
How many 4K cameras can the NVR301-08B-P8-IQ record and show at the same time?
It can record all 8 as 4K as long as the total stays within 80 Mbps, which means up to 10 Mbps each; at a typical 8 Mbps per 4K camera, 8 cameras use 64 Mbps. For display, the decoder handles 2 streams at 4K@30 at full resolution (or 4 × 4MP and 8 × 1080P), so the 8-camera split screen shows lower-resolution streams and you open one camera full screen to see full detail.
Which hard drive should I fit in the NVR301-B-P-IQ and how many days will it record?
One 3.5-inch SATA surveillance-grade drive built for 24/7 writing, up to 24 TB if the room stays at or below 40 °C. Recording continuously at 4 Mbps per camera, a 4 TB drive keeps about 23.1 days with 4 cameras or 11.6 days with 8; a 24 TB drive keeps about 138.9 or 69.4 days. Event-based recording and Ultra 265 give more.
How far can a camera be from the NVR301-08B-P8-IQ PoE port?
Up to 100 m of Cat5e or Cat6 solid copper cable per port, the standard Ethernet/PoE limit; the ports are 10/100 Mbps and IEEE 802.3af/at. For a camera farther away, put a PoE switch or PoE extender within 100 m of it, or use fibre to a remote switch. Avoid copper-clad aluminium cable, which causes power drops and cameras that reboot at night when the IR turns on.
What is the difference between the NVR301-08B-P8-IQ and the NVR301-08B-LP8-IQ?
Recording, smart functions, 8 PoE ports and the 75 W budget are the same on both datasheets. The differences are physical: the 08B-P8-IQ is 260 × 222 × 47 mm, fits the RM-1U-260 rack tray, and allows the 24 TB disk in rooms up to 40 °C; the 08B-LP8-IQ is 270 × 212 × 46 mm and its datasheet sets 35 °C for the largest disk. The LP family also has a 16-channel model (16B-LP8-IQ) if you may grow past 8 cameras.
