CHOOSE YOUR SIZE — THREE MODELS ON THIS PAGE

Rule of thumb: count your cameras, then leave room to grow — a site with 9 cameras runs comfortably on the 09B; pick the 16B or 32B if you may add cameras later, or need the extra HDD bay for RAID 1 redundancy. Highlighted rows in the spec table below show every difference between the three.

The Uniview NVR502-B Series is a 2-HDD network video recorder offered in three sizes: NVR502-09B (9-ch), NVR502-16B (16-ch) and NVR502-32B (32-ch). All three record cameras up to 16MP with Ultra 265 / H.265 / H.264 compression, output simultaneously over 4K HDMI and VGA, and include built-in Smart by IPC detection (Face Detection, Face Comparison, Vehicle Detection, Temperature Detection) plus VCA search (face, vehicle, human body, people counting, heat map). Two SATA bays each take a hard disk up to 24 TB with RAID 1 mirroring support; 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.

Right-sized, room to growThe 9-ch 09B covers a compact site today; the 16B and 32B share the same 2-bay chassis so you can size up without learning a new interface.

Large sites need disk redundancyTwo SATA bays with RAID 1 mirroring mean a single disk failure doesn't wipe out your footage — worth it once a site runs 16 or 32 cameras.

AI-assisted monitoringBuilt-in Face Detection, Face Comparison, Vehicle Detection (LPR) and Temperature Detection flag real events across all channels — no more scrubbing hours of empty footage.

Search by event, not by scrubbingVCA Search finds a face, a vehicle, a person or a crowd spike in seconds — with People Counting Report and Heat Map for foot-traffic analysis.

Remote viewing on phoneP2P protocol built in — the owner checks the site from a phone app without a fixed IP or network skills.

Fast backup via USB 3.0Three USB ports total — one on the front for quick access, plus one USB 2.0 and one USB 3.0 on the rear — pulling recorded footage onto a drive is fast even with everything else plugged in.

Not the right pick if you need…

PoE ports — cameras need a separate PoE switch (we bundle one at combo price)
RS232 serial control — the port is N/A on this series (RS485 is present for PTZ control)
More than 2 hard disks or RAID 5/6/10 — this chassis has 2 SATA bays with RAID 1 (mirroring) only
Simultaneous local snapshot on more than 4 channels — Snapshot is capped at 4-ch (max. D1 resolution) regardless of model size
Full 32-channel synchronous local playback on the NVR502-32B — local playback tops out at 16-ch even though this model accepts 32 camera inputs

Protects your footage. Finds the moment.

Two real capabilities from the datasheet that matter every day: disk redundancy and built-in smart search.

RAID 1 MIRRORING

One disk fails, footage survives

Two SATA bays run in RAID 1 mirroring — if one disk fails, the second keeps recording and holds an identical copy, so a hardware failure doesn't mean lost evidence.

SMART BY IPC

Real alerts, not hours of nothing

Built-in Face Detection, Face Comparison, Vehicle Detection (LPR) and Temperature Detection run across all channels (up to 8 images/s total), feeding Face Snapshot Search, Motor/Non-Motor Vehicle Search, Human Body Search, People Counting Report and Heat Map — search by event, not by scrubbing the timeline.

9/16/32-Channel NVR FAQ — NVR502-B Series

How many IP cameras can I connect?

The NVR502-09B takes 9 IP cameras, the 16B 16 and the 32B 32, recording up to 16 MP per channel. Incoming bandwidth is 320 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.

What happens if a hard drive fails?

The two SATA bays (up to 24 TB each) support Disk Group and Redundant Storage with RAID 1 mirroring, so both disks hold an identical copy of critical footage. A single drive failure then doesn't stop recording or lose the protected footage — worth enabling on sites where video is evidence, such as shops, warehouses and residential compounds.

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.

Can I connect alarm sensors and sirens?

Yes — it has 8 alarm inputs and 2 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.

Does it support face detection and smart search?

Yes — with UNV smart cameras, every channel can report Face Detection, Face Comparison, Vehicle Detection (LPR) and Temperature Detection events (up to 8 images/s total). The NVR indexes these events for VCA Search — face snapshot/comparison, vehicle and human-body search — so you jump straight to the right clip instead of scrubbing hours of video.

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 160 Mbps.
