Rule of thumb: count your cameras, then leave room to grow — a 9-camera site runs happily on the 09B-IQ; pick the 16B-IQ or 32B-IQ if you may add cameras later. One detail worth knowing: on the 32B-IQ, local synchronous playback is limited to 16 channels at a time even though it records all 32 — highlighted rows in the spec table below show every other difference.

The Uniview NVR302-B-IQ Series is a 2-HDD network video recorder offered in three sizes: NVR302-09B-IQ (9-ch), NVR302-16B-IQ (16-ch) and NVR302-32B-IQ (32-ch). All three record cameras up to 12MP with Ultra 265 / H.265 / H.264 compression, run built-in face detection, face comparison and vehicle detection (LPR), and output simultaneously over 4K HDMI and VGA. Two SATA bays each take a hard disk up to 24 TB, and 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-to-mid installationsThe 9-ch 09B-IQ plus nine cameras is a complete kit — two disks, one screen, real face-detection search built in.
Growing or multi-building projectsBuy channels you don't use yet: the 16B-IQ or 32B-IQ lets you add cameras later without replacing the recorder.
Remote viewing on phoneP2P protocol built in — the owner checks the site 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.
Retail loss-prevention & analyticsFace Snapshot Search, People Counting Report and Heat Map turn hours of footage into a store-traffic report — plus POS overlay on every channel to match transactions to video.
Longer video retentionUltra 265 roughly halves file size versus H.264 — two 24 TB disks keep months more footage than a single-bay recorder.
Vehicles & gate / parking projectsVehicle Detection (LPR) plus Motor and Non-Motor Vehicle Search, with a library for up to 25,000 vehicle pictures — useful for gates, parking lots and logistics yards.
Not the right pick if you need…
- PoE ports — cameras need a separate PoE switch (we bundle one at combo price)
- RS-485 / RS-232 serial control ports — both are not present on this series
- Alarm in/out wiring for sirens or sensors — the physical interface list shows none on this series
- Full Smart-feature channel counts with third-party cameras — deepest face 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

Who uses it, where to install it and how to size it
Written for the NVR302-09B-IQ, NVR302-16B-IQ and NVR302-32B-IQ from the official datasheet: 9, 16 or 32 channels, 160 Mbps incoming bandwidth, 2 SATA bays up to 24 TB each, recording up to 12 MP, no built-in PoE.
Who it is for
- Shops, offices and schools with up to 9 cameras (09B-IQ) — Nine channels with 160 Mbps of bandwidth leave about 17.8 Mbps per camera, enough for 8 MP or 12 MP cameras, and two disks give long retention for a small site.
- Mid-size sites and multi-building projects (16B-IQ, 32B-IQ) — Warehouses, hotels, factories and campuses: the cameras connect through your own PoE switches over the 2 gigabit ports, and the 32B-IQ shows up to 32 cameras on one screen.
- Retail chains and loss prevention — People Counting Report and Heat Map show store traffic, POS text can be overlaid on all channels to match a sale to the video, and Face Snapshot Search finds a person without watching hours of footage.
- Gates, parking and logistics yards — With Uniview LPR cameras, Vehicle Detection plus Motor and Non-Motor Vehicle Search work on the recorder, with up to 5 vehicle picture libraries and 25,000 vehicle pictures in total for allow and block lists.
Where and how to install
- Rack or shelf, locked away — The unit is 380 × 315 × 53 mm and about 2 kg without disks. For a 19-inch cabinet order the RM-1U-380 2-HDD 1U rack mount; otherwise use a solid shelf. Install it in a locked room or cabinet so nobody can remove the recorder and the disks.
- Keep the disks below 40 °C — The recorder itself runs from -10 °C to 55 °C, but the datasheet says the environment should not exceed 40 °C when the disks are in use. Leave free air around the case, do not stack it under a hot switch, and in hot climates use an air-conditioned room or a ventilated cabinet with fans.
- PoE switch and cabling — There are no PoE ports, so plan a PoE switch with enough ports and PoE budget for your cameras and a gigabit uplink to one of the recorder's 2 gigabit RJ45 ports (1000 M). Keep every copper run from switch to camera under 100 m; use a fibre SFP link or a second switch for buildings farther away.
- Power and UPS — The recorder uses a DC 12 V / 3 A adapter and draws ≤ 12 W without disks. Put the recorder, its disks and the PoE switch on the same UPS: if the switch loses power the cameras go dark even while the recorder keeps running.
- Monitor, audio and USB — Connect the main monitor by HDMI (up to 4K) and a second one by VGA if needed: both outputs work at the same time. The RCA audio in and out give 1-channel two-way audio, and the front USB 2.0 port is handy for a mouse or for exporting clips to a USB drive.
Planning table: 09B-IQ, 16B-IQ or 32B-IQ
All three share 160 Mbps of incoming bandwidth and two 24 TB bays, so the extra channels of the bigger models come with less bandwidth and fewer days per camera. Whatever the model, a recorder running at the full 160 Mbps fills 48 TB in about 27.8 days.

| Retention on 48 TB, all channels at 8 Mbps (days) | ≈ 62 | ≈ 35 | — (256 Mbps > 160 Mbps) |
- Pick the 09B-IQ for up to 9 cameras: even at 8 Mbps each, two 24 TB disks keep about 62 days.
- Pick the 16B-IQ for 10 to 16 cameras; 16 cameras at 4 Mbps keep about 69 days on 48 TB.
- Pick the 32B-IQ for 17 to 32 cameras, but plan about 5 Mbps per camera on average (4 MP in H.265 or Ultra 265) to stay within 160 Mbps.
Retention = total disk TB × 10^12 ÷ (cameras × bitrate ÷ 8 × 86400 s), continuous recording on both disks filled to 24 TB, no reserve. 4 Mbps is an assumed average for a 4 MP H.265 camera, 8 Mbps for an 8 MP camera. Decoding figures are @30 fps from the official datasheet; live view of many cameras uses sub-streams.

9/16/32-Channel AI NVR FAQ — NVR302-B-IQ Series
How many IP cameras can I connect?
The NVR302-09B-IQ takes 9 IP cameras, the 16B-IQ 16 and the 32B-IQ 32, recording up to 12 MP per channel. Incoming bandwidth is 160 Mbps, so size camera bitrates to stay inside that figure, and pick the channel count that leaves room to add cameras as the site grows.
How many hard drives fit and what is the maximum capacity?
Two independent SATA bays, each taking a cctv hdd up to 24 TB — up to 48 TB of local storage without RAID complexity. Use surveillance-rated hard drives; real retention depends on camera count, resolution and bitrate, and Ultra 265 keeps files smaller than H.264 at the same image quality, stretching every terabyte further.
What AI functions are built into the recorder itself?
The NVR runs Face Detection, Face Comparison, Smart Intrusion Prevention (SIP) and Ultra Motion Detection on board: up to 8 face channels with UNV face-detection cameras or 1 with standard cameras, plus SIP on 2 and UMD on 4 standard channels. AcuSearch, AcuTrack and face/vehicle/human-body search make playback filterable.
Does it have built-in PoE ports?
No — this series has no PoE ports. It connects through two gigabit RJ45 interfaces, and cameras are powered by an external PoE switch on the LAN. That layout suits projects where cameras are spread across floors or buildings rather than home-run to the recorder.
How much storage does Ultra 265 save compared with H.264?
Roughly half the storage for the same image: Ultra 265 cuts recording size dramatically versus H.264, so the same 24 TB disk keeps footage for weeks longer — or records more cameras at higher resolution. H.265 and H.264 are also supported for mixed camera fleets.
Can I view live video remotely?
Yes — up to 128 remote users can connect. The recorder supports P2P, DDNS, HTTP/HTTPS and RTSP and works in a browser (IE10/11, Chrome 45+, Edge 79+, Firefox 52+), so an integrator can check several client sites from one office. Outgoing bandwidth for remote streams is 128 Mbps.
Which smart functions still work on the NVR302-16B-IQ if I use Hikvision, Dahua or other third-party cameras?
With normal cameras (Uniview or third-party) the recorder itself analyses only a few channels: face detection on 1 channel (2 MP), SIP intrusion/line rules on up to 2 channels (2 × 2 MP or 1 × 4 MP) and Ultra Motion Detection on up to 4 channels (4 × 2 MP, 2 × 4 MP or 1 × 4K). AcuSearch and AcuTrack on all channels and face detection on up to 8 channels need Uniview cameras with those functions. ONVIF is not named in the datasheet protocol list, so send us your camera models and we will confirm they can be added before you order.
Do the two disks in the NVR302 B-IQ mirror each other (RAID)?
No. RAID is not listed for this series: the two SATA bays add up, so two 24 TB disks give 48 TB of recording space. If one disk fails, the footage stored on that disk is lost, but the recorder keeps recording on the other. If the video must survive a disk failure, look at the NVR504-16B-IQ / NVR504-32B-IQ, which is a 4-HDD RAID recorder.
How many 4K or 12 MP cameras can the NVR302-32B-IQ handle?
The limit is the 160 Mbps incoming bandwidth, not the 32 channels: at 8 Mbps per 4K camera that is 20 cameras, at 5 Mbps average it is all 32. Live view and playback are limited by decoding: 2 × 12 MP or 2 × 4K streams at full resolution, so a 16- or 32-screen view shows sub-streams, and local synchronous playback is 16 channels at a time. For many 4K cameras with longer retention, a larger recorder such as the NVR304 or NVR504 series is the better fit.
What does ANR on the NVR302 B-IQ do if the network goes down?
ANR (automatic network replenishment) fills the gap in the recording after a network break. While the link between camera and recorder is down, a camera with a microSD card keeps recording locally; when the link comes back, the recorder copies the missing part from the card. It only works with cameras that support ANR and have a card fitted, so it is worth using on cameras at the end of long or outdoor links.
Which hard drives should I install in the NVR302 B-IQ?
Use 3.5-inch SATA drives made for surveillance (rated for 24/7 writing), up to 24 TB each in the 2 bays. The datasheet notes that the maximum usable capacity depends on drive size and ambient temperature, and that the environment should not exceed 40 °C during use, so in hot rooms choose ventilation first. Two disks of the same size make retention easier to predict; you can start with one disk and add the second later.
