The Uniview NVR301-B-IQ Series is a 1-HDD network video recorder offered in three sizes: NVR301-04B-IQ (4-ch), NVR301-08B-IQ (8-ch) and NVR301-16B-IQ (16-ch). All three record cameras up to 12MP with Ultra 265 / H.265 / H.264 compression, output simultaneously over 4K HDMI and VGA, and include built-in Smart Function covering face detection, face comparison, vehicle detection (LPR) and traffic monitoring. 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 & homesThe 4-ch 04B-IQ plus four cameras with built-in Smart Function is a complete kit — one disk, one screen, done.
Growing businessesBuy channels you don't use yet: the 08B-IQ/16B-IQ lets you add 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), French, Korean and Japanese — 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 months more footage even at 12MP.
Vehicle & people analyticsVehicle Detection (LPR), Motor/Non-Motor Vehicle Search, People Counting and Heat Map turn parking lots and storefronts into searchable, measurable traffic data.
Face-based quick searchFace Detection and Face Comparison feed Face Snapshot Search and Face Comparison Search — investigations that took hours now take minutes.
Not the right pick if you need…
- 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 even at 80 Mbps total bandwidth)
- Alarm in/out wiring for sirens or sensors — RS485/RS232 and alarm terminals are not present on this model
- Full Smart-feature channel counts with third-party cameras — deepest face/vehicle AI (up to 8-ch) requires Uniview cameras; normal/third-party cameras are limited to 1-ch face detection, 2-ch SIP or 4-ch UMD

Sharper footage. Smarter search.
Two real capabilities from the datasheet that matter every day: higher-resolution recording within a normal storage budget, and built-in AI search across faces, vehicles and people.
12MP RECORDING
Sharper footage, same efficient storage
Ultra 265 compression cuts recording size dramatically versus H.264 — on the same up-to-24 TB disk you can record at up to 12MP and still keep footage for weeks longer than older H.264 systems.
SMART SEARCH SUITE
Face, vehicle and people — all searchable
Built-in Face Detection, Face Comparison, Vehicle Detection (LPR) and People Counting/Heat Map feed AcuSearch, AcuTrack, Face Snapshot/Comparison Search and Vehicle Search — up to 8 channels with Uniview cameras — so an investigation that took hours now takes minutes.

Who uses it, where it goes and how to install it
Written for the NVR301-04B-IQ, 08B-IQ and 16B-IQ from the official datasheet: 4, 8 or 16 IP channels, 80 Mbps incoming bandwidth, 1 SATA bay up to 24 TB, 4K HDMI plus VGA, no built-in PoE.
Which size suits which installation
- NVR301-04B-IQ: shops, homes and small offices — Up to 4 cameras on one disk and one screen. With 80 Mbps shared by only 4 channels, each camera can use up to 20 Mbps, so even 12 MP or 4K cameras record at full quality.
- NVR301-08B-IQ: restaurants, clinics and growing businesses — 8 channels with face detection on up to 8 Uniview face-detection cameras; buy it when you have 4–6 cameras today and expect to add more without changing the recorder.
- NVR301-16B-IQ: warehouses, schools and multi-floor sites — 16 channels of 2–4 MP cameras fit comfortably in 80 Mbps (16 × 4 Mbps = 64 Mbps). With 16 cameras on one disk, plan the drive size carefully: see the retention rows below.
- Car parks, gates and retail with Uniview smart cameras — Vehicle detection (LPR) by the camera with up to 5 vehicle picture libraries / 25,000 pictures, plus people counting reports, heat map and POS overlay on all channels for stores.
Where and how to install the recorder
- Desk, shelf or 1U rack — The case is 260 × 222 × 47 mm (1U). Put it on a shelf in a locked office or cabinet, or in a 19-inch rack with the RM-1U-260 tray. Keep it out of reach of visitors so a thief cannot take the recorder with the evidence.
- Keep the disk cool — The recorder works from -10 °C to 55 °C, but the datasheet limits large disks to rooms that do not exceed 40 °C. Leave space around the vents, do not stack other equipment on top, and avoid hot roof spaces or closed metal boxes in the sun.
- Power and UPS — It runs from a DC 12 V / 2 A adapter and has no power switch, so it restarts by itself when power returns. Put the recorder, the PoE switch and the router on one small UPS: the cameras keep recording through short outages and the disk is not hit by sudden power cuts.
- Cameras through a separate PoE switch — There are no PoE ports: cameras plug into a PoE switch, and one cable runs from the switch to the recorder's single 10/100 Mbps RJ45 port. Keep each camera run within 100 m of Cat5e/Cat6 copper, and keep the total camera bitrate under the 80 Mbps incoming limit.
- Disk and screens — Fit one 3.5-inch SATA surveillance-grade disk (up to 24 TB) before powering on and format it in the recorder. HDMI (up to 4K) and VGA work at the same time, so you can drive a monitor at the counter and one in the office; use the rear USB 3.0 port for fast clip export.
Planning table: channels, bandwidth, disk and retention
All three share the same 80 Mbps input, single SATA bay and outputs; what changes is the channel count, how much bandwidth each channel gets when all are used, the decoding capacity and the face-detection channels. One disk holds all cameras, so retention drops as channels are added.

| Days on 24 TB, all channels at 4 Mbps | 138.9 | 69.4 | 34.7 |
- Pick the 04B-IQ for up to 4 cameras, including 4K or 12 MP: each channel can take up to 20 Mbps.
- Pick the 08B-IQ for 5–8 cameras or when you want face detection on all 8 channels with Uniview face cameras.
- Pick the 16B-IQ for 9–16 cameras of 2–4 MP; with 4K cameras on all 16 channels each must stay at or below 5 Mbps.
Retention assumes continuous 24-hour recording at 4 Mbps per camera (a typical H.265 main stream for a 4 MP camera): days = TB × 10^12 ÷ (cameras × 4,000,000 ÷ 8 × 86,400). Ultra 265, lower frame rates or event-only recording give more days; 8 MP cameras at about 8 Mbps give half. The 24 TB maximum applies only if the room stays at or below 40 °C.

4/8/16 Channel AI NVR FAQ — NVR301-B-IQ
What AI functions are built into this NVR?
Face detection, face comparison, vehicle detection (LPR), smart intrusion prevention (SIP) and Ultra Motion Detection — both camera-side on all channels and NVR-side. Results feed AcuSearch, AcuTrack, face snapshot/comparison search, motor and non-motor vehicle search, plus search by image. Up to 5 vehicle libraries hold 25,000 plates.
How many cameras and at what resolution?
4, 8 or 16 IP cameras depending on the model, recording at up to 12MP per channel with 80 Mbps of incoming bandwidth. With Smart mode off the decoder handles 2×12MP@30 or 2×4K@30 plus 4×4MP@30 for local display, and playback runs up to 16 channels concurrently.
How big a hard drive can I fit?
One SATA bay accepts a surveillance hard drive up to 24 TB (maximum usable capacity varies with ambient temperature and disk model). Combined with Ultra 265 compression, that single bay covers long retention even when recording 16 cameras at high resolution.
Do the AI functions work with third-party cameras?
Yes, within limits: NVR-side face detection runs on 1 channel at 2MP with a normal third-party camera, SIP on up to 2 channels at 2MP (or 1 at 4MP) and UMD on up to 4 channels at 2MP. Full-performance AcuSearch and AcuTrack need UNV SIP/UMD cameras.
Is it suitable for shops with POS systems?
Yes — POS integration is available on all channels, so till text can be tied to video. It also supports 16 IP speakers, 1-channel two-way audio over RCA, and event/schedule/FTP snapshots, which suits retail loss-prevention setups in busy stores.
What display outputs and languages does it support?
HDMI up to 4K (3840×2160) at 30 Hz and VGA up to 1920×1080 at 60 Hz. The GUI covers 38 languages, including Latin American Spanish and Brazilian Portuguese. Remote access supports 128 users over P2P, DDNS, HTTPS, RTSP, SNMP and 802.1x, with 80 Mbps outgoing.
How many 4K (8 MP) cameras can the NVR301-16B-IQ really record?
The limit is the 80 Mbps incoming bandwidth, not the channel count. At a typical 8 Mbps per 4K camera that is 10 cameras (10 × 8 = 80 Mbps); to put 4K on all 16 channels, each must be set to 5 Mbps or less with Ultra 265/H.265. For live view and playback the decoder handles 2 streams at 4K@30 at full resolution, so large split screens use lower-resolution streams.
Do I need a separate PoE switch with the NVR301-08B-IQ, and which one?
Yes. The B-IQ series has no PoE ports, only one 10/100 Mbps RJ45 port, so the cameras need a PoE switch with at least as many PoE ports as cameras (IEEE 802.3af gives up to 15.4 W per port, 802.3at up to 30 W). Connect one switch port to the recorder; a 100 Mbps link is enough because the recorder accepts at most 80 Mbps. If you need PoE in the recorder itself, look at the NVR301-04B-P4-IQ / 08B-P8-IQ or the LP4/LP8 versions.
Which hard drive should I buy for the NVR301-B-IQ, and how many days will it keep?
Use one 3.5-inch SATA surveillance-grade drive (made for 24/7 writing), up to 24 TB; the 24 TB limit assumes a room at or below 40 °C. At 4 Mbps per camera, continuous, a 4 TB drive keeps about 23.1 days for 4 cameras, 11.6 days for 8 and 5.8 days for 16; a 24 TB drive keeps about 138.9, 69.4 and 34.7 days. Motion or smart-event recording and Ultra 265 stretch this further.
Can I watch the NVR301-04B-IQ on my phone without a fixed IP address?
Yes. P2P is in the protocol list, so the recorder is added to the Uniview phone app by scanning its code, with no port forwarding or fixed IP; DDNS and UPnP are also listed for setups that need them. Up to 128 remote users and 80 Mbps outgoing are supported, but in practice the site's internet upload speed decides how many cameras you can watch smoothly at once. Firmware can also be updated over the cloud.
Can face recognition, intrusion detection and AcuSearch run at the same time on the NVR301-B-IQ?
Not when the recorder itself does the analysis. In NVR analyzer mode only one mode is active at a time: Face Recognition, SIP, UMD or AcuSearch/AcuTrack. If the cameras do the analysis (Smart by IPC with Uniview smart cameras), face, vehicle, SIP and UMD events from all channels are received together, up to 8 images per second in total, so for several functions on one site choose smart cameras.
Can I record Hikvision, Dahua or other non-Uniview cameras on the NVR301-B-IQ?
The datasheet expects third-party cameras: it gives smart limits for 'UNV and third-party brand' normal cameras (for example UMD on up to 4 channels of 2 MP). Third-party cameras are normally added over ONVIF, but ONVIF is not named in the datasheet's protocol list, so send us your camera models and we will confirm before you order. For mixed systems plan on basic recording and motion events from other brands, and full smart search from Uniview cameras.
