Choose your size — three models on this page
Rule of thumb: count your cameras across the whole site, then leave room to grow — a mid-size site runs happily on the 32E-R; pick the 64E-R or 128E-R for large multi-building deployments. Highlighted rows in the spec table below show every difference between the three.

The Uniview NVR508-E-R Series is an 8-bay 2U rack-mount network video recorder offered in three sizes: NVR508-32E-R (32-ch), NVR508-64E-R (64-ch) and NVR508-128E-R (128-ch). All three record cameras up to 32MP with Ultra 265 / H.265 / H.264 compression, support hot-swappable SATA drives (up to 24 TB each) configurable as RAID 0, 1, 5, 6 or 10, and accept an optional second power supply for redundancy. The recorder outputs over 2 HDMI and 2 VGA ports, includes Smart features such as face, vehicle (LPR) and temperature detection, and provides a 38-language local interface.
Is this the right recorder for you?
Plain-language guide for buyers and installers — based only on what this recorder actually does.
Large multi-building sites128 channels and 8 hot-swap HDD bays cover a large campus from one recorder — fewer boxes to manage across buildings.
Growing deploymentsBuy channels ahead: the 64E-R/128E-R lets you add cameras later without swapping the recorder.
Mission-critical, zero-downtime storageHot-swap RAID 0/1/5/6/10 across the 8 bays plus N+1 hot spare and an optional second power supply — a failed disk or PSU doesn't take the recorder down.
Unreliable network linksANR technology keeps recording locally when the network drops, then backfills the gap once the connection is restored.
Investigation & retrievalFace, face comparison, vehicle (LPR), human body, heat-map and people-counting search narrow hours of footage across up to 128 channels down to the right clip.
Two independent display zonesHDMI1/VGA1 and HDMI2/VGA2 output independently — a control room can show a live wall on one screen pair and playback on the other.
Multi-language deployments38 GUI languages including Spanish (Latin America), Portuguese (Brazil) and French — your customer operates it in their own language.
Not the right pick if you need…
- PoE ports — this recorder has no built-in PoE; cameras need a separate PoE switch
- A redundant power supply included as standard — the manual lists it as an optional add-on module (PWR-DC12-350A-IN), not pre-installed
- Full per-channel bandwidth headroom at 128 channels — 384 Mbps incoming bandwidth is shared across all channels, so plan the average bitrate per camera accordingly at the top model
- A dedicated two-way audio port — two-way audio reuses the shared RCA audio input/output jacks, not a separate connector
- More than one eSATA expansion port — only 1× eSATA is provided for external storage

Who uses it, where it goes and how to size it
Written for the NVR508-32E-R, 64E-R and 128E-R from the official datasheet: 32, 64 or 128 IP channels sharing 384 Mbps, 8 hot-swap SATA bays up to 24 TB each with RAID 0/1/5/6/10, optional redundant power supply (PWR-DC12-350A-IN), recording up to 32 MP, two independent HDMI/VGA output pairs, no built-in PoE.
Which size suits which installation
- NVR508-32E-R: mid-size sites that cannot stop recording — 32 cameras at up to 12 Mbps each, so 4K on every channel is possible (32 × 8 = 256 Mbps). Hot-swap disks and the optional second power supply mean a failed disk or PSU is replaced while the recorder keeps running.
- NVR508-64E-R: large sites and control rooms — 64 cameras at 6 Mbps each when all are used, suited to 4–5 MP cameras on H.265. Both output pairs show large layouts: up to 64 tiles on HDMI1/VGA1 and 36 on HDMI2/VGA2, more than the 16 of the NVR508-E-IQ second output.
- NVR508-128E-R: campuses with many 2 MP cameras — 128 channels in one 2U box, but they share the same 384 Mbps: 3 Mbps per camera when all are used. It suits 1080P and 2 MP cameras, or a mix where only some channels carry 4K.
- Projects built on Uniview smart cameras — The E-R series does no analytics itself: face, LPR, SIP and UMD events come from Uniview smart cameras on all channels (up to 16 images/s in total) and are searched on the recorder, with up to 5 vehicle libraries of 25,000 pictures for car parks.
Where and how to install the recorder
- 19-inch rack, 2U, front access — The case is 442 × 448 × 93 mm and up to 6 kg before disks. Mount it with the FL-2U rack mount, supported underneath, and leave the front free: hot-swap disks are pulled from the front, so do not block it with a fixed shelf or cables.
- Two power supplies on two circuits — Power is AC 100–240 V, up to 35 W without disks. A second supply is optional: order the PWR-DC12-350A-IN 350 W module. Connect the two supplies to different circuits or to a UPS and the mains, so one tripped breaker or failed UPS does not stop recording.
- Cooling for eight disks — The recorder is rated -10 °C to 55 °C, but 24 TB disks need a room at or below 40 °C. Keep front and rear vents clear, leave a gap above and below in the rack, and use an air-conditioned equipment room in hot climates.
- 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; 384 Mbps cannot pass through a 100 Mbps uplink. With 128 cameras, spread them over several access switches and set each camera's bitrate so the total stays under 384 Mbps.
- Build the array, keep a spare disk — Fit eight identical 3.5-inch SATA surveillance-grade drives and build RAID 5 or RAID 6 before recording starts, because creating an array erases the disks. Keep one identical drive on site: with hot swap, the failed disk is pulled and replaced while the recorder keeps running and the array rebuilds.
Planning table: channels, bandwidth, disks and retention
All three share the 2U case, 384 Mbps input and output, eight hot-swap bays with RAID 0/1/5/6/10, the optional redundant PSU and the same top decoding (2 × 32 MP or 8 × 4K at 30 fps). What changes is the channel count, so the bandwidth per camera drops from 12 to 6 to 3 Mbps when every channel is used, and the same disks are shared by more cameras.

| Days in RAID 6 (144 TB), all channels at 3 Mbps | 138.9 | 69.4 | 34.7 |
- Pick the 32E-R for up to 32 cameras, including all-4K sites, when hot-swap disks and a redundant PSU matter more than channel count.
- Pick the 64E-R for 33–64 cameras at about 6 Mbps or less each, or when you need large layouts on both screen pairs.
- Pick the 128E-R for 65–128 cameras of 1080P/2 MP at about 3 Mbps; for recorder-side face or intrusion analysis, look at the NVR508-32E-R-IQ / 64E-R-IQ.
Retention assumes continuous 24-hour recording at 3 Mbps per camera (a typical H.265 main stream for a 2 MP camera, and the most each of 128 channels can use: 384 ÷ 128): days = TB × 10^12 ÷ (cameras × 3,000,000 ÷ 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). 8 Mbps per 4K camera is a typical H.265 value. 24 TB disks require a room at or below 40 °C.

32/64/128-Channel Hot-Swap RAID NVR FAQ — NVR508-E-R
How many IP cameras can the NVR508-E-R series record?
32, 64 or 128 IP cameras depending on the model, all with 384 Mbps incoming and 384 Mbps outgoing bandwidth. Recording resolution reaches 32 MP per channel, and decoding covers up to 8x 4K at 30 fps or 32x 1080P at 30 fps for live view and playback.
Can I replace a failed hard drive without stopping the recorder?
Yes. The 8 SATA bays are hot-swappable and support RAID 0, 1, 5, 6 and 10 with N+1 hot spare — you pull the failed drive and insert a new one while the array and the recordings keep working. Each bay accepts up to 24 TB, 192 TB total.
Does the NVR508-E-R have PoE ports for the cameras?
No PoE ports — this is a central rack recorder with two gigabit RJ45 interfaces, one eSATA port and a 12 V power output. Feed the cameras from PoE switches in the field and bring the streams back to the NVR over the network.
What smart search can I run across 128 channels?
The recorder receives AI metadata from the cameras (Smart by IPC, up to 16 images/s in total): face detection and comparison, vehicle detection with LPR and temperature detection. You then run face snapshot, vehicle, human body and general VCA searches, plus heat map and people counting, with up to 25,000 vehicle pictures stored.
Can I monitor the system remotely?
Yes. Up to 128 remote users can connect at the same time via P2P, HTTP/HTTPS, RTSP or DDNS, and outgoing bandwidth is 384 Mbps for remote streams. Supported browsers are Chrome 45+, Edge 79+, Firefox 52+ and IE10/11.
How many days will the NVR508-128E-R keep with 128 cameras on eight disks?
With 128 cameras each can use at most 3 Mbps (384 ÷ 128). At 3 Mbps continuous, eight 24 TB disks keep about 40.5 days in RAID 5 (168 TB) and about 34.7 days in RAID 6 (144 TB). If you need 60 days or more at that camera count, record on motion or smart events, lower the frame rate, or split the cameras over two recorders.
Is the redundant power supply on the NVR508-E-R included, and how should I wire it?
No, it is optional: the datasheet lists the PWR-DC12-350A-IN 350 W power module as an accessory for the second supply slot, so add it to your order if you want redundancy. With two supplies, feed them from two different sources, for example one from the UPS and one from a separate mains circuit; if both come from the same socket strip, the redundancy protects only against a failed supply, not a failed feed.
Can I record Hikvision, Dahua or other non-Uniview cameras on the NVR508-E-R?
Usually yes for video, but check first. Third-party cameras are normally added over ONVIF, and ONVIF is not named in this datasheet's protocol list (RTSP is), so send us your camera models and we will confirm before you order. Expect recording, live view and basic motion alarms from other brands; the face, vehicle and SIP/UMD search on this series comes from Uniview smart cameras, because the E-R recorder does no analysis itself.
What is the difference between the NVR508-64E-R and the NVR508-64E-R-IQ?
Both are 8-bay hot-swap recorders with RAID 0/1/5/6/10 and an optional redundant PSU. The 64E-R relies on Uniview smart cameras for analytics and takes a flat 384 Mbps; the IQ version adds analysis by the recorder itself (face, SIP, UMD, also on some ordinary cameras) and AcuSearch/AcuTrack. Choose the 64E-R when your cameras are already smart or you only need recording, and the E-R series when you need 128 channels, which only the 128E-R offers.
RAID 5 or RAID 6 on the NVR508-E-R, and which drives should I use?
Use eight identical 3.5-inch SATA surveillance-grade drives, up to 24 TB each in a room at or below 40 °C. RAID 5 keeps about 168 TB and survives one failed disk; RAID 6 keeps about 144 TB and survives two, which matters with large disks because rebuilding a 24 TB disk takes many hours and a second disk can fail meanwhile. With hot swap and a spare drive on site, RAID 6 is the safer default for 64 or 128 cameras.
