Rule of thumb: count your cameras across the whole site, then leave room to grow — 16 channels covers most single buildings; step up to the 32B-P16-IQ if you're combining several buildings or expect to add cameras later (note: only the first 16 channels have built-in PoE on either model). Highlighted rows in the spec table below show every difference between the two.

The Uniview NVR304-B-P16-IQ Series is a 16-port PoE, 4-HDD network video recorder offered in two sizes: NVR304-16B-P16-IQ (16-ch) and NVR304-32B-P16-IQ (32-ch), with 16 built-in PoE ports delivering up to 30 W per port (150 W total budget, IEEE 802.3at/af). 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, Vehicle Detection (LPR) and AcuSearch / AcuTrack smart search. Four independent 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.
Cameras plug in and power up — no switch needed16 built-in PoE ports (30 W per port, 150 W total budget, IEEE 802.3at/af) power and connect cameras with a single cable — most 16-camera installs need no separate PoE switch.
Large sites & multi-building campuses16 or 32 channels in one box covers a full warehouse, factory floor, or multi-story retail location without stacking multiple recorders.
Long-term evidence retentionFour SATA bays, up to 24 TB each (up to 96 TB total), keep months of footage online instead of overwriting after a few weeks.
Growing camera countsBuy channels you don't use yet: the 32B-P16-IQ lets you add cameras later without replacing the recorder (only the first 16 channels get built-in PoE — see the notes below).
Remote viewing on phoneP2P protocol built in — the manager checks every 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.
Longer video retention per driveUltra 265 roughly halves file size versus H.264 — the same 24 TB disk keeps weeks more footage.
Quick incident lookup across many channelsBuilt-in Face Detection, Face Comparison and Vehicle Detection (LPR) feed AcuSearch, AcuTrack and Face Snapshot Search — jump straight to the clip you need instead of scrubbing hours of footage across 16 or 32 channels.
Not the right pick if you need…
- Powering all 32 cameras via built-in PoE on the 32B-P16-IQ — this series has 16 PoE ports regardless of model; channels 17–32 on the 32-ch unit need a separate switch or injector
- A second/redundant network uplink — only one 10/100/1000M RJ45 network interface is provided (separate from the 16 PoE camera ports)
- RS232 serial connection — RS232 is listed N/A on this series (RS485 is provided, e.g. for PTZ control)
- A fifth hard disk or more — this series tops out at 4 SATA bays (up to 96 TB total with four 24 TB drives)
- Redundant/dual power input — it runs on a single AC 100–240 V power supply, no built-in PSU redundancy

16 ports of PoE. AI finds the moment.
Two real capabilities that define this series: built-in 16-port PoE and onboard AI search.
16-PORT POE
Cameras plug in and power up
16 independent PoE ports deliver up to 30 W per port (150 W total budget, IEEE 802.3at/af) — cameras get power and data over one cable, and most 16-camera installs skip a separate PoE switch entirely.
AI SEARCH
Find the moment, not the footage
Built-in Face Detection, Face Comparison and Vehicle Detection (LPR) on the camera side feed AcuSearch, AcuTrack, Face Snapshot Search and Human Body Search on the recorder — narrow hours of footage down to the exact clip.

Who uses it, where to install it and how to size it
Written for the NVR304-16B-P16-IQ and NVR304-32B-P16-IQ from the official datasheet: 16 or 32 channels, 16 built-in PoE ports (30 W per port, 150 W total), 160 Mbps incoming bandwidth, 4 SATA bays up to 24 TB each, 16 alarm inputs and 4 outputs.
Who it is for
- 16-camera sites that want one box (16B-P16-IQ) — Warehouses, supermarkets, hotels and factories: 16 cameras plug straight into the recorder for power and video, so there is no separate PoE switch to buy, power and maintain.
- Main building plus outbuildings (32B-P16-IQ) — The 16 PoE ports serve the main building; up to 16 more cameras in a second building or yard come in through a PoE switch on the gigabit network port, all on one recorder and one 32-screen live view.
- Sites with alarm sensors, sirens or PTZ keyboards — 16 alarm inputs, 4 alarm outputs and an RS485 port let door contacts, PIR detectors and sirens work with the video; the 2-bay and non-PoE NVR304 models have no alarm terminals.
- Projects that need months of evidence — Up to 96 TB on four disks: 16 cameras at 4 Mbps keep about 139 days. Retail chains also get POS overlay, People Counting Report and Heat Map with Uniview smart cameras.
Where and how to install
- Central spot, 100 m rule — Every camera on a built-in PoE port needs its own cable of at most 100 m (Cat5e/Cat6 copper), so place the recorder near the middle of the 16 cameras. Cameras farther away go on a PoE extender or a switch on the network port.
- Cabinet shelf, cable management — The case is 400 × 369 × 74 mm and about 4 kg without disks. Put it on a fixed shelf in a 19-inch cabinet or a solid desk in a locked room; label all 16 camera cables and use a patch panel so a camera can be swapped without tracing cables.
- Heat: PoE plus four disks — With 150 W of PoE and four drives inside, this recorder runs warm. The datasheet limits the environment to 40 °C when disks are in use (the unit itself is rated -10 °C to 55 °C), so keep the vents free and use an air-conditioned room or a cabinet with fans in hot climates.
- Power and UPS sizing — Power is AC 100–240 V through a single internal supply (no redundant input). Size the UPS for the full PoE load: up to 150 W for cameras plus ≤ 12 W for the recorder, plus the disks. On mains cut the UPS keeps all 16 PoE cameras alive, not only the recorder.
- Surge, alarm and RS485 wiring — For cameras on poles or outside walls, fit Ethernet surge protectors with a good earth so lightning does not reach the PoE ports. Run alarm and RS485 wires as separate low-voltage cables, away from mains cables, and label each input and output at the terminal.
Planning table: 16B-P16-IQ or 32B-P16-IQ
Both models have the same 16 PoE ports, 150 W budget, 160 Mbps bandwidth and 96 TB of disk space. The 32B-P16-IQ only adds 16 more channels for cameras connected through a switch on its network port, plus a 25/32-screen live view and 32 × D1 decoding. The 150 W budget averages about 9.4 W per port when all 16 ports are used.

| Retention on 96 TB, all channels at 8 Mbps (days) | ≈ 69 | — (256 Mbps > 160 Mbps) |
- Pick the 16B-P16-IQ when all cameras can reach the recorder within 100 m and you will not exceed 16 cameras: no external switch at all.
- Pick the 32B-P16-IQ when a second building or future expansion will add up to 16 more cameras through a PoE switch; keep the average near 5 Mbps per camera.
- Mixing PTZs? Add up the real draw: for example 12 IR cameras at 6 W plus 4 compact PTZs at 13 W use 124 W of the 150 W budget.
Retention = total disk TB × 10^12 ÷ (cameras × bitrate ÷ 8 × 86400 s), continuous recording on four 24 TB disks, no reserve. Assumptions: 4 Mbps per 4 MP H.265 camera, 8 Mbps per 8 MP camera, 6 W per IR camera, 13 W per compact PTZ. PoE, bandwidth and decoding values are from the official datasheet.

16-Port PoE AI NVR FAQ — NVR304-B-P16-IQ Series
How many cameras can the NVR304-16B-P16-IQ power directly?
Both models have 16 built-in PoE ports with a 150 W total budget; on the 32B-P16-IQ the other 16 cameras join via the LAN. Each PoE port delivers up to 30 W (IEEE 802.3at/af), so typical 4–12 W IP cameras plug straight into the recorder — power and video over one cable, no separate PoE switch needed.
How many IP cameras can I connect?
The NVR304-16B-P16-IQ records 16 IP cameras and the 32B-P16-IQ records 32, 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?
Four independent SATA bays, each taking a disk up to 24 TB — up to 96 TB in one recorder for long retention or high channel counts. 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.
Can I connect alarm sensors and sirens?
Yes — it has 16 alarm inputs and 4 alarm outputs plus an RS485 port, so PIR sensors, door contacts or sirens wire directly to the recorder and can trigger recording, snapshots or notifications alongside the video events.
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.
How do I connect cameras 17 to 32 on the NVR304-32B-P16-IQ?
Through a PoE switch connected to the recorder's single 10/100/1000 M network port, which also carries remote viewing. Use a switch with a gigabit uplink and enough PoE budget for those cameras, and keep each camera run under 100 m. All 32 cameras together still share the 160 Mbps incoming bandwidth, so plan about 5 Mbps per camera on average.
Can the NVR304-16B-P16-IQ power PTZ cameras from its PoE ports?
Yes, if each PTZ needs 30 W or less (IEEE 802.3at) and the total stays within 150 W. A compact PTZ at about 13 W is fine: 11 of them would use 143 W, or mix 12 IR cameras at 6 W with 4 such PTZs for 124 W. Large PTZs with heaters or long-range IR that need high-power PoE (802.3bt) or 24 V AC must have their own power supply, and you can still record them on any free channel.
A camera is 150 m from the NVR304 B-P16-IQ. Can I still use a built-in PoE port?
Not on a single cable: standard Ethernet with PoE is specified for 100 m of Cat5e/Cat6 copper, and beyond that video drops out or the camera reboots. Add a PoE extender in the middle of the run, put a small PoE switch near the camera fed from the recorder's network port, or use fibre for long distances. Use pure copper cable; copper-clad aluminium cable loses PoE power over long runs.
If one disk fails in the NVR304-16B-P16-IQ, do I lose everything?
No, only what was stored on that disk. RAID is not listed in the official datasheet for this series, so the four bays work as independent disks (up to 96 TB in total) and the others keep recording. Replace the failed drive and initialise the new one in the recorder. If footage must survive a disk failure, ask us about a RAID recorder such as the NVR504-16B-IQ / 32B-IQ with a separate PoE switch.
Can I plug Hikvision, Dahua or other third-party cameras into the NVR304 B-P16-IQ PoE ports?
Power will work with any IEEE 802.3af/at camera, but adding the video depends on the camera's protocol support, and ONVIF is not named in the datasheet protocol list. The datasheet does mention third-party cameras for recorder-side smart functions, limited to 1 channel of face detection, 2 of SIP and 4 of Ultra Motion Detection; AcuSearch and AcuTrack need Uniview cameras. Send us the camera models and we will confirm before you order.
