Choose your size — two models on this page
Rule of thumb: count your cameras across the whole site, then leave room to grow — 32 channels covers most single campuses; step up to the 64E-R-IQ if you're combining several buildings or expect a large expansion. Highlighted rows in the spec table below show every difference between the two.

The Uniview NVR508-E-R-IQ Series is an 8-HDD network video recorder offered in two sizes: NVR508-32E-R-IQ (32-ch) and NVR508-64E-R-IQ (64-ch). Both record cameras up to 32MP with Ultra 265 / H.265 / H.264 compression, support RAID 0, 1, 5, 6 and 10 with Disk Group and Redundant Storage across eight independent SATA bays (up to 24 TB each), and include built-in Face Detection, Vehicle Detection (LPR), Temperature Detection and AcuSearch / AcuTrack smart search. Two independent HDMI+VGA output pairs support up to 4K/60Hz, 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 campuses32 or 64 channels in one box, with eight RAID-protected SATA bays, covers a full campus, data center or multi-story facility without stacking multiple recorders.
Uptime-critical storageDisk Group and Redundant Storage with RAID 0, 1, 5, 6 or 10 across eight hot-swappable bays, plus N+1 Hot spare and an optional redundant power supply module, mean a single failed drive, PSU — or even a failed recorder — doesn't take coverage offline.
Multi-room control centersTwo independent HDMI+VGA output pairs let one recorder drive two separate video walls or control-room monitors at once, each up to 4K/60Hz.
Growing camera countsBuy channels you don't use yet: the 64E-R-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.
Quick incident lookup across many channelsBuilt-in Face Detection, Vehicle Detection (LPR) and Temperature Detection feed AcuSearch, AcuTrack and Face Snapshot Search — jump straight to the clip you need instead of scrubbing hours of footage across 32 or 64 channels.
Not the right pick if you need…
- PoE ports — cameras need a separate PoE switch (this recorder has no built-in PoE ports)
- A ninth hard disk or more — this series tops out at 8 SATA bays (up to 192 TB total with eight 24 TB drives)
- Three or more independent monitor feeds — this series provides two independent HDMI+VGA output pairs (4 physical ports, 2 independent video feeds)
- Low-voltage DC 12V power input — this unit runs on AC 100–240V only, no DC power-brick option
- Running Face Recognition/AcuSearch and SIP/UMD analytics at the same time — Smart by NVR Analyzer Mode runs one mixed mode at a time, not both simultaneously

Eight bays, RAID protected. AI finds the moment.
Two real capabilities that define this series: RAID-protected multi-bay storage and onboard AI search.
8-BAY RAID STORAGE
Room to grow, protected against drive or unit failure
Eight independent, hot-swappable SATA bays each take a disk up to 24 TB — up to 192 TB in one recorder, with Disk Group and Redundant Storage supporting RAID 0, 1, 5, 6 or 10, plus N+1 Hot spare and an optional redundant power supply module, so a failed drive, a failed PSU — or a failed recorder — doesn't stop recording.
AI SEARCH
Find the moment, not the footage
Built-in Face Detection, Vehicle Detection (LPR) and Temperature Detection on the camera side (up to 16 images/s in total) 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 it goes and how to size it
Written for the NVR508-32E-R-IQ and 64E-R-IQ from the official datasheet: 32 or 64 IP channels, 384 or 512 Mbps incoming (200 Mbps with smart analysis on), 8 hot-swap SATA bays up to 24 TB each with RAID 0/1/5/6/10, optional redundant power supply, analysis by the recorder itself, no built-in PoE.
Which size suits which installation
- NVR508-32E-R-IQ: critical sites with up to 32 cameras — Up to 12 Mbps per camera with smart analysis off (384 Mbps ÷ 32), so 4K works on every channel; disks swap while recording and a second power supply can be added, for sites such as bank branches, hospitals or data rooms where downtime is not accepted.
- NVR508-64E-R-IQ: large sites up to 64 cameras — 512 Mbps with smart analysis off gives 8 Mbps per camera with all 64 used, enough for 64 4K cameras on H.265; with recorder analysis on, the 200 Mbps limit means about 3 Mbps per camera, so plan which cameras need analysis.
- Sites with ordinary cameras that need intrusion alarms — The recorder itself runs SIP on up to 8 channels of 2 MP and UMD on up to 16 channels of 2 MP from ordinary cameras, Uniview or third-party, so perimeter alarms can be added without replacing every camera.
- Integrators who want the full redundancy set — Among the 8-bay AI recorders on our site this series adds hot-swap disks and an optional redundant power supply to RAID 0/1/5/6/10 and N+1 hot spare; the NVR508-E-IQ has the same AI but neither of those two.
Where and how to install the recorder
- 19-inch rack, 2U, front access — The case is 443 × 448 × 93 mm and up to 6.5 kg before disks, deeper than the 432 mm NVR508-E-IQ, so check the rack depth. Mount it with the FL-2U rack mount, supported underneath, and keep the front clear: hot-swap disks come out from the front.
- Two power supplies on two feeds — Power is AC 100–240 V, up to 35 W without disks. For redundancy add the PWR-DC12-350A-IN 350 W module and feed the two supplies from different sources, for example one from the UPS and one from a separate mains circuit.
- Cool room: 50 °C limit, 40 °C for large disks — This series is rated -10 °C to 50 °C, 5 °C lower than the NVR508-E-R without AI, and 24 TB disks need a room at or below 40 °C. With eight drives, use an air-conditioned equipment room or a ventilated rack and keep front and rear vents free.
- Gigabit camera network — There are no PoE ports. Cameras go to PoE switches (each copper run within 100 m) with gigabit uplinks to one of the two gigabit RJ45 ports. Spread 64 cameras over several access switches so no single uplink carries the full 512 Mbps plus other traffic.
- Disks, RAID and alarm wiring — Fit eight identical 3.5-inch SATA surveillance-grade drives, build RAID 6 or RAID 5 before recording (creating an array erases the disks) and keep one spare drive on site for hot swap. Wire door contacts, sirens and lights to the 16 alarm inputs and 10 alarm outputs; use USB 3.0 or eSATA for exports.
Planning table: channels, bandwidth, disks and retention
Both share the 2U hot-swap case, eight bays with RAID 0/1/5/6/10, the optional redundant PSU, 32 MP recording, the same top decoding and the 200 Mbps limit with smart analysis on. The 64E-R-IQ doubles the channels and raises the smart-off input from 384 to 512 Mbps; the RAID level decides how much of the 192 TB is usable.
| NVR508-32E-R-IQ | NVR508-64E-R-IQ | |
|---|---|---|
| IP camera channels | 32 | 64 |
| Incoming bandwidth (Smart Off / Smart On) | 384 / 200 Mbps | 512 / 200 Mbps |
| Bandwidth per camera, all channels used (Smart Off / Smart On) | 12 / 6.25 Mbps | 8 / 3.125 Mbps |
| 4K cameras at 8 Mbps (Smart Off / Smart On) | 32 / 25 | 64 / 25 |
| Hard disks | 8 × SATA hot-swap, ≤ 24 TB each (192 TB) | 8 × SATA hot-swap, ≤ 24 TB each (192 TB) |
| Usable on 8 × 24 TB: RAID 5 / RAID 6 / RAID 10 | 168 / 144 / 96 TB | 168 / 144 / 96 TB |
| Power supply | AC 100–240 V + optional PWR-DC12-350A-IN | AC 100–240 V + optional PWR-DC12-350A-IN |
| Largest split screen (HDMI1/VGA1 / HDMI2/VGA2) | 32 / 16 | 64 / 16 |
| Days in RAID 5 (168 TB), all channels at 4 Mbps | 121.5 | 60.8 * |
| Days in RAID 6 (144 TB), all channels at 4 Mbps | 104.2 | 52.1 * |
- Pick the 32E-R-IQ for up to 32 cameras, including all-4K sites (32 × 8 = 256 Mbps fits 384 Mbps with smart analysis off), when the recorder must keep running through a disk or PSU failure.
- Pick the 64E-R-IQ for 33–64 cameras; turn recorder analysis on only if the total camera bitrate stays under 200 Mbps, otherwise let Uniview smart cameras do the analytics.
- If you do not need hot swap or a redundant PSU, the NVR508-32E-IQ / 64E-IQ gives the same channels and AI in a lighter case; if you need 128 channels, look at the NVR508-128E-R.
Retention assumes continuous 24-hour recording at 4 Mbps per camera (a typical H.265 main stream for a 4 MP camera): days = TB × 10^12 ÷ (cameras × 4,000,000 ÷ 8 × 86,400). Usable space on eight equal 24 TB disks: RAID 5 = 7 disks (168 TB), RAID 6 = 6 disks (144 TB), RAID 10 = 4 disks (96 TB). * 64 cameras at 4 Mbps = 256 Mbps, which fits 512 Mbps with smart analysis off but not the 200 Mbps limit with it on. 8 Mbps per 4K camera is a typical H.265 value; 24 TB disks require a room at or below 40 °C.

32/64-Channel AI Hot-Swap NVR FAQ — NVR508-E-R-IQ
How many cameras does the NVR508-E-R-IQ take, and what changes with AI on?
The 32E-R-IQ records 32 IP cameras and the 64E-R-IQ records 64, at up to 32 MP per channel. Incoming bandwidth is 384 Mbps (32E-R-IQ) or 512 Mbps (64E-R-IQ) with smart functions off, and 200 Mbps with NVR-side analytics running — size your camera bitrates to that figure.
Which AI features run on the recorder, and do third-party cameras work?
The NVR runs Face Detection/Comparison, Smart Intrusion Prevention (SIP) and Ultra Motion Detection (UMD), one analyzer mode at a time. Face recognition: up to 16 channels with UNV face cameras or 4 channels with normal cameras. SIP handles up to 8 channels and UMD up to 16 channels of 2 MP cameras, UNV or third-party.
How is storage handled — can I swap disks while it runs?
Eight hot-swap SATA bays each take a drive up to 24 TB — 192 TB total — with RAID 0, 1, 5, 6 and 10, disk group and redundant storage. Hot swap means a failed disk is replaced without powering down, so recording continues during maintenance.
Can it drive two monitors with different content?
Yes. Two HDMI and two VGA outputs are provided; HDMI1/VGA1 and HDMI2/VGA2 display independent content, with HDMI up to 4K at 60 Hz. The 64E-R-IQ splits the main screen into up to 64 windows, corridor mode is available, and POS overlay works on all channels.
Can I monitor the system remotely?
Yes. The recorder supports P2P, HTTP/HTTPS and RTSP with up to 128 simultaneous remote users, from Chrome 45+, Edge 79+, Firefox 52+ or IE10/11. Outgoing bandwidth is 384 Mbps (32E-R-IQ) or 512 Mbps (64E-R-IQ) with smart off, 200 Mbps with smart on.
NVR508-64E-R-IQ or NVR508-64E-IQ: what do I get for choosing the R-IQ?
The channels, 512/200 Mbps bandwidth, RAID 0/1/5/6/10, N+1 hot spare and recorder-side AI are the same. The R-IQ adds hot-swap disk bays, so a failed disk is replaced while the recorder keeps recording, and a slot for an optional redundant power supply (PWR-DC12-350A-IN). In exchange it is larger and heavier: 443 × 448 × 93 mm and up to 6.5 kg, against 442 × 432 × 86 mm and 5.5 kg.
How many days will the NVR508-E-R-IQ keep in RAID 6, and is RAID 6 worth the lost space?
With eight 24 TB disks, RAID 6 leaves about 144 TB: at 4 Mbps per camera, continuous, that is about 104.2 days for 32 cameras and 52.1 days for 64, against about 121.5 and 60.8 days in RAID 5. RAID 6 survives two failed disks at once, which matters with 24 TB drives because a rebuild takes many hours and a second disk can fail meanwhile. With hot swap and a spare disk on site, RAID 6 is the safe default; choose RAID 5 only when every terabyte counts.
Which analyzer mode should I pick on the NVR508-E-R-IQ: Face Recognition + AcuSearch or SIP + UMD?
Only one mixed mode runs on the recorder at a time, so choose by the main risk. Face Recognition + AcuSearch suits entrances and reception desks (face by the recorder on up to 16 channels with Uniview face detection cameras, or 4 channels of 2 MP ordinary cameras). SIP + UMD suits fences, yards and after-hours areas (up to 8 or 16 channels of 2 MP ordinary cameras). If you need both, use Uniview smart cameras for one of them, because analysis done by the cameras arrives on all channels in either mode.
Is the redundant power supply for the NVR508-E-R-IQ included?
No. The datasheet lists redundant power supply as supported and the PWR-DC12-350A-IN 350 W power module as an accessory, so order it together with the recorder if you want two supplies. Then feed the two supplies from separate sources, such as the UPS and a different mains circuit; on one socket strip the second supply protects only against a failed module, not against a lost feed.
What network switches do I need between the cameras and the NVR508-64E-R-IQ?
PoE switches for the cameras, because the recorder has no PoE ports, each with a gigabit uplink: up to 512 Mbps of camera video can arrive, far more than a 100 Mbps link can carry. Connect the camera switches, or a gigabit core switch that aggregates them, to one of the recorder's two gigabit RJ45 ports, keep each camera run within 100 m of Cat5e/Cat6, and size each switch's PoE budget for the cameras on it.
