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.
- 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

Key Features
Complete list from the official datasheet.
Four bays of storage. AI finds the moment.
Two real capabilities that define this series: large multi-bay storage and onboard AI search.
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.
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.
