The Uniview NVR502-B-P-IQ Series is a 2-HDD PoE network video recorder offered in three sizes: NVR502-08B-P8-IQ (8-ch, 8 built-in PoE ports), NVR502-16B-P16-IQ (16-ch, 16 built-in PoE ports) and NVR502-32B-P16-IQ (32-ch, 16 built-in PoE ports). 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 Function covering face detection, face comparison, vehicle detection (LPR) and people counting / heat map analytics. Two SATA bays each take a hard disk up to 24 TB with RAID 1 support, 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 & mid-size sitesThe 8-ch 08B-P8-IQ plus eight PoE cameras is a complete kit — one box powers, records and runs Smart Function for the whole site.
No separate PoE switch needed8 or 16 built-in PoE ports mean cameras plug straight into the recorder — one cable per camera, no extra power supply on site.
Large sites needing headroomThe 32-ch 32B-P16-IQ covers parking lots, campuses and multi-building sites — 16 cameras run on built-in PoE, the rest connect over the network.
Redundant storageTwo SATA bays with RAID 1 mirroring protect footage from a single disk failure — important for sites that can't afford lost evidence.
Vehicle & people analyticsVehicle Detection (LPR), Motor/Non-Motor Vehicle Search, People Counting and Heat Map turn parking lots and storefronts into searchable, measurable traffic data.
Face-based quick searchFace Detection and Face Comparison feed Face Snapshot Search and Face Comparison Search — investigations that took hours now take minutes.
Not the right pick if you need…
  • RS232 serial control — this series has RS485 only, no RS232 port
  • RAID 0/5/6 arrays — the 2-bay Disk Array Type supports RAID 1 mirroring only, not striping or parity RAID
  • High-power PoE++ cameras — Max Power is capped at 30W per single port (IEEE 802.3at/af standard, not 60W+ PoE++)
  • Full 8-channel Smart AI with third-party cameras — the deepest face/vehicle AI (up to 8-ch) requires Uniview cameras; normal/third-party cameras are limited to 2-ch face detection, 4-ch SIP or 8-ch UMD
  • 4K @ 60Hz output — HDMI tops out at 4K (3840×2160)/30Hz; 60Hz refresh is only available at 1080p and below

Sharper footage. Smarter search.

Two real capabilities from the datasheet that matter every day: higher-resolution recording with mirrored dual-bay storage, and built-in AI search across faces, vehicles and people.

16MP RECORDING + RAID 1

Sharper footage, mirrored for safety

Ultra 265 compression keeps recording size efficient even at up to 16MP, and two SATA bays up to 24 TB each can mirror each other with RAID 1 — footage survives a single disk failure.

SMART SEARCH SUITE

Face, vehicle and people — all searchable

Built-in Face Detection, Face Comparison, Vehicle Detection (LPR) and People Counting/Heat Map feed AcuSearch, AcuTrack, Face Snapshot/Comparison Search and Vehicle Search — up to 8 channels with Uniview cameras — so an investigation that took hours now takes minutes.

Who uses it, where it goes and how to install it

Written for the NVR502-08B-P8-IQ, NVR502-16B-P16-IQ and NVR502-32B-P16-IQ from the official datasheet: 8, 16 or 32 channels, 8 or 16 PoE ports (130 W or 240 W), 320 Mbps input (160 Mbps with Smart on), face/SIP/UMD analysis in the recorder itself, 2 SATA bays up to 24 TB each with RAID 1.

Which size suits which installation

  • NVR502-08B-P8-IQ: small sites that want AI without AI cameras — Shops and offices with ordinary cameras: the recorder itself can run intrusion (SIP) on up to 4 channels of 2 MP cameras or motion classification (UMD) on up to 8, with 8 PoE ports and 130 W to power them.
  • NVR502-16B-P16-IQ: retail and hospitality with watch-lists — Supermarkets, hotels and clinics: face comparison on up to 8 channels with Uniview face-detection cameras, POS text on all channels and up to 16 IP speakers, all 16 cameras powered from 240 W of built-in PoE.
  • NVR502-32B-P16-IQ: car parks and campuses — Up to 32 cameras, 16 on built-in PoE and the rest through a switch; with Uniview LPR cameras it keeps up to 5 vehicle picture libraries (25,000 pictures). Plan bitrates carefully: with Smart on, 160 Mbps leaves 5 Mbps per camera.
  • Investigators who search instead of scroll — AcuSearch and AcuTrack (all channels with Uniview SIP/UMD cameras), search by image and records for 2 million face and 2 million vehicle snapshots make it fit for loss-prevention teams and security managers.

Where and how to install the recorder

  • Cooler spot than a basic NVR — The IQ version is rated -10 °C to 50 °C (the non-IQ NVR502-B-P goes to 55 °C), and the largest disks need the room at 40 °C or less. Mount it in a ventilated 19-inch cabinet with the RM-1U-380 kit (1U, 380 × 322 × 53 mm) or on an open shelf, away from the router's and switch's exhaust.
  • Mains supply, UPS and PoE load — The internal supply takes AC 100–240 V and has a power switch. Size the UPS for the recorder (≤ 12 W without disks), two disks and the PoE load — up to 130 W on the 08B-P8-IQ and 240 W on the 16B/32B models — so cameras and analysis keep running in a blackout.
  • Disks: RAID 1 and array alarms — Fit two identical surveillance-grade drives and decide at commissioning whether to mirror them (RAID 1, usable space of one disk). The IQ firmware adds Array Damaged and Array Degraded alerts — send them to the owner's phone or e-mail so a failed disk is replaced before the second one goes.
  • Aim the cameras for the analysis — Face detection and comparison only work on faces seen nearly head-on: mount entrance cameras at about 2.5–3.5 m, looking along the walking direction, not steeply down. For SIP/UMD keep trees, flags and headlights out of the detection area to cut false alarms.
  • PoE runs, extra switch and gigabit LAN — Each PoE port (10/100M, 802.3af/at, max 30 W) feeds one camera over Cat5e/Cat6 copper up to 100 m, with surge protection on outdoor runs. On the 32B-P16-IQ, cameras 17–32, IP speakers and POS devices join through a switch on the 10/100/1000M LAN port.

Planning table: channels, PoE, bandwidth, disk and retention

The key planning point for the IQ series: switching Smart (recorder-side analysis) on halves the incoming bandwidth from 320 to 160 Mbps and lowers decoding, so decide which mode the site runs before you set camera bitrates.

  • Pick the NVR502-08B-P8-IQ for up to 8 cameras when you want recorder-side SIP/UMD on ordinary cameras; even with Smart on, each camera still has 20 Mbps.
  • Pick the NVR502-16B-P16-IQ for 9–16 cameras on built-in PoE; with Smart on, keep each camera at 10 Mbps or less (4 MP H.265 at 4 Mbps fits easily).
  • Pick the NVR502-32B-P16-IQ for 17–32 cameras, but if Smart will be on, plan 5 Mbps or less per camera or move the analysis into Uniview AI cameras (Smart by IPC) and leave Smart off.

Bandwidth per camera = incoming bandwidth ÷ channels (Smart off 320 Mbps, Smart on 160 Mbps). Retention = usable TB × 10^12 ÷ (cameras × bitrate ÷ 8 × 86400 s), assuming 4 Mbps per camera (typical 4 MP H.265, 24 h). RAID 1 usable space = one disk. Other values: official datasheet.

PoE AI NVR FAQ — NVR502-B-P-IQ Series

Do the IQ models power the cameras too?
Yes — PoE is built in: the NVR502-08B-P8-IQ has 8 PoE ports and the 16B-P16-IQ and 32B-P16-IQ have 16, as the model suffix shows. Power and video run over one network cable, so most sites skip the separate PoE switch; ask us to match the PoE budget to your camera list.
How many IP cameras can I connect?
The NVR502-08B-P8-IQ records 8 IP cameras, the 16B-P16-IQ 16 and the 32B-P16-IQ 32, up to 16 MP per channel. Incoming bandwidth is 320 (160 with Smart mode on) 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.
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 2 with standard cameras, plus SIP on 4 and UMD on 8 standard channels. AcuSearch, AcuTrack and face/vehicle/human-body search make playback filterable.
Can I find a person from a photo?
Yes — Search by Image is supported: load a face picture and the recorder hunts for matches in its indexed snapshots. It keeps up to 2 million face snapshot records and 2 million vehicle records, so even busy commercial sites stay searchable months later.
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.
What changes on the NVR502-32B-P16-IQ when I switch Smart on?
Incoming bandwidth drops from 320 Mbps to 160 Mbps and decoding drops too (for example 4 × 4K@30 becomes 2 × 4K@30, and the 32-channel figure goes from 720P to D1). With 32 cameras that is 5 Mbps each on average, so set camera bitrates to fit before enabling the analysis. If your cameras are Uniview AI models, their own analysis (Smart by IPC) gives searchable events without using the recorder's Smart mode.
How many ordinary or third-party cameras can the NVR502-B-P-IQ analyse itself, and can it run several AI functions at once?
With normal cameras (Uniview or third-party) the datasheet allows face detection on 2 channels at 2 MP or 1 at 4 MP, SIP on 4 × 2 MP, 2 × 4 MP or 1 × 4K, and UMD on 8 × 2 MP, 4 × 4 MP or 2 × 4K. Only one analyzer mode can be active at a time (Face Recognition, SIP, UMD or AcuSearch/AcuTrack). Uniview face-detection cameras raise face analysis to 8 channels, and AcuSearch/AcuTrack need Uniview SIP/UMD cameras.
Does the NVR502-B-P-IQ read number plates by itself?
No. In the datasheet, Vehicle Detection (LPR) is listed under Smart by IPC, so plates are read by an LPR camera and the recorder stores and searches the results. The recorder's own analysis (Smart by NVR) covers face detection, face comparison, SIP and UMD only. With LPR cameras it keeps up to 5 vehicle picture libraries with 25,000 pictures in total and up to 2 million vehicle snapshot records.
Can the NVR502-16B-P16-IQ show cash-register (POS) data and play announcements through IP speakers?
The datasheet lists POS input on all channels and IP speakers on up to 16 channels as peripheral inputs, which the non-IQ NVR502-B-P does not have. Which POS systems and speaker models work is not detailed, so tell us your cash-register software and speaker model and we will confirm before ordering. Both devices connect over the network, through the LAN port or a switch.
What is the difference between the NVR502-16B-P16-IQ and the NVR502-16B-P16?
Same chassis, 16 PoE ports with 240 W, 2 disk bays with RAID 1, 8 alarm inputs / 2 outputs and 320 Mbps with Smart off. The IQ adds analysis in the recorder (face, SIP, UMD, AcuSearch/AcuTrack), search by image, POS and IP speaker inputs, 8 MP event snapshots and array alarms. In exchange its input falls to 160 Mbps with Smart on and its maximum working temperature is 50 °C instead of 55 °C.
How many face and vehicle snapshots does the NVR502-B-P-IQ keep?
The datasheet gives 2 million face snapshot records, 2 million vehicle snapshot records, 3 million SIP records and 2 million video metadata records. These records are what Face Snapshot Search, vehicle search and AcuSearch look through, separate from the video retention you size with the disks. A busy entrance can generate thousands of face snapshots a day, so expect the oldest records to be overwritten on long-running sites.
