NVR304-16 / 32B-IQ

16 / 32-channel network video recorder — four SATA bays for large-capacity storage, Ultra 265 compression, 4K HDMI output, records cameras up to 12MP, with onboard Face Detection, Vehicle Detection (LPR) and AI smart search.

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-IQ if you're combining several buildings or expect to add cameras later. Highlighted rows in the spec table below show every difference between the two.

The Uniview NVR304-B-IQ Series is a 4-HDD network video recorder offered in two sizes: NVR304-16B-IQ (16-ch) and NVR304-32B-IQ (32-ch). 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.

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-IQ lets you add cameras later without replacing the recorder.
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…
  • PoE ports — cameras need a separate PoE switch (this recorder has no built-in PoE ports)
  • 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
  • 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 DC 12 V/5 A power supply, no built-in PSU redundancy

Four bays of storage. AI finds the moment.

Two real capabilities that define this series: large multi-bay storage and onboard AI search.

4-BAY STORAGE

Room to grow, in one box

Four independent SATA bays each take a disk up to 24 TB — up to 96 TB in one recorder, useful for high channel counts or long retention without an external storage array.

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.
