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.
- 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

Key Features
Complete list from the official datasheet.
Eight bays, RAID protected. AI finds the moment.
Two real capabilities that define this series: RAID-protected multi-bay storage and onboard AI search.
Room to grow, protected against drive or unit failure
Eight independent 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 so a failed drive — or a failed recorder — doesn't stop recording.
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-IQ and 64E-IQ from the official datasheet: 32 or 64 IP channels, 384 or 512 Mbps incoming (200 Mbps with smart analysis on), 8 SATA bays up to 24 TB each with RAID 0/1/5/6/10 and N+1 hot spare, recording up to 32 MP, two independent HDMI/VGA output pairs, no built-in PoE.
Which size suits which installation
- NVR508-32E-IQ: campuses with high-resolution cameras — 32 channels share 384 Mbps, so each camera can use up to 12 Mbps with smart analysis off: enough for 4K and 8 MP cameras on every channel, with eight disks for long retention.
- NVR508-64E-IQ: large sites with 64 cameras, up to 4K — Unlike the 32E-IQ (384 Mbps), the 64E-IQ takes 512 Mbps with smart analysis off: 8 Mbps per camera when all 64 are used, enough for 64 4K cameras on H.265 with recorder smart analysis off.
- Sites that cannot lose footage — RAID 6 survives two failed disks at once and RAID 10 rebuilds faster; N+1 hot spare lets a standby recorder take over if a working recorder fails. Array Degraded and Array Damaged alarms warn before footage is at risk.
- Control rooms and retail chains — Two independent output pairs drive two separate screens or walls (HDMI up to 4K/60 Hz). POS input on all channels, people counting reports and heat maps from Uniview smart cameras help stores check tills and customer flow.
Where and how to install the recorder
- 19-inch rack, 2U — The case is 442 × 432 × 86 mm (2U), up to 5.5 kg before eight disks are added. Mount it with the FL-2U rack mount in a locked rack, supported underneath rather than by the front ears alone, and keep it in a room only staff can enter.
- Cool room: 50 °C limit, 40 °C for large disks — This series is rated -10 °C to 50 °C, 5 °C lower than the 4-bay NVR504-E-IQ, and 24 TB disks need a room at or below 40 °C. With eight drives running, use an air-conditioned equipment room or a ventilated rack, and keep the vents free.
- Mains power and UPS — Single AC 100–240 V supply, up to 35 W without disks; eight drives add their own load. Size the UPS for the recorder, the PoE switches and the router together, so recording continues through outages and the RAID array is not damaged by sudden power loss.
- Cameras through PoE switches — There are no PoE ports. Cameras go to PoE switches (each copper run within 100 m) with a gigabit uplink to one of the recorder's two gigabit RJ45 ports. At 512 Mbps the 64E-IQ needs more than one 100 Mbps link can carry, so every switch in the camera path must be gigabit.
- Disks, RAID and wiring before handover — Fit eight identical 3.5-inch SATA surveillance-grade drives and build the array before recording starts, because creating it erases the disks. Wire door contacts and sirens to the 16 alarm inputs and 10 alarm outputs, and keep a USB 3.0 drive or the eSATA port for exports.
Planning table: channels, bandwidth, disks and retention
Both share the 2U case, eight SATA bays with RAID 0/1/5/6/10, 32 MP recording, the same top decoding and the 200 Mbps limit with smart analysis on. The 64E-IQ adds 32 channels and raises the smart-off input from 384 to 512 Mbps; the RAID level you choose decides how much of the 192 TB you can actually use.

|---|---|---|
| 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 |

| Hard disks | 8 × SATA, ≤ 24 TB each (192 TB) | 8 × SATA, ≤ 24 TB each (192 TB) |
| Usable on 8 × 24 TB: RAID 5 / RAID 6 / RAID 10 | 168 / 144 / 96 TB | 168 / 144 / 96 TB |
| Decoding, Smart Off | 2×32MP, 8×4K, 16×4MP, 32×1080P @30 | same + 64×720P @30 |
| 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-IQ for up to 32 cameras, including all-4K sites (32 × 8 = 256 Mbps fits 384 Mbps with smart analysis off).
- Pick the 64E-IQ for 33–64 cameras; with recorder smart analysis on, the 200 Mbps limit means about 3 Mbps per camera, so let the cameras do the analytics on large 4K sites.
- Choose RAID 6 when the site is far from service or uses large disks with long rebuilds; RAID 5 when capacity matters most; RAID 10 for the fastest rebuild at half the capacity.
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 needs smart analysis off. 8 Mbps per 4K camera is a typical H.265 value. 24 TB disks require a room at or below 40 °C.
