Both record cameras up to 12MP with Ultra 265 / H.265 / H.264 compression, support 16 hot-swappable SATA drives (up to 24 TB each) configurable as RAID 0, 1, 5, 6, 10, 50 or 60 with an N+1 hot spare, and accept an optional second power supply for redundancy. The recorder outputs over 2 independent HDMI ports (up to 4K) plus 1 VGA port, includes Smart functions such as face, vehicle (LPR) and temperature detection on supported cameras, 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.
- 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 a second unit as an optional add-on module (PWR-DC12-350A-IN), not pre-installed
- More than 2 independent HDMI outputs — additional HDMI channels require an optional decoding card (FB-HD04-B-NB / FB-HD07-B-NB) in one of the 2 extension slots
- Deeper NVR-side Smart analytics — the manual refers this to a separate "Smart Card" datasheet; the search types listed on this page (face, vehicle, human body) are IPC-side detection or VCA search
- A small handful of cameras — this is a 16-bay rack chassis built for large sites; a compact desktop NVR is a better fit for a few cameras

Key Features
Complete list from the official datasheet.
Hot-swap RAID storage. Investigation-ready search.
The two capabilities that decide whether a large-scale recorder survives a hardware failure and finds the footage that matters.
Swap a failed disk without downtime
16 hot-swap SATA bays (up to 24 TB each) configurable as RAID 0, 1, 5, 6, 10, 50 or 60, plus an N+1 hot spare — a failed drive is pulled and replaced while the array and the recorder keep running.
Find the moment across 128 channels
Face snapshot search, face comparison search, motor and non-motor vehicle search, human body search and general search turn hours of multi-channel footage into the exact clip you need.

Who uses it, where it goes and how to size it
Written for the Uniview NVR816-64 and NVR816-128 from the official datasheet: 64 or 128 channels sharing 512 Mbps incoming, 16 hot-swap SATA bays up to 24 TB each with RAID 0/1/5/6/10/50/60, 2 extension slots, 4 × Gigabit RJ45, optional second power supply.
Which variant suits which project
- NVR816-64: up to 64 cameras, all of them 4K — Large factories, hotels and hospitals. Its 512 Mbps input gives 8 Mbps per channel even with all 64 in use, so every camera can be 4K/8 MP on H.265, with 12 MP cameras where more detail is needed.
- NVR816-128: up to 128 cameras of 2–4 MP — Campuses, industrial parks and multi-building sites. The same 512 Mbps over 128 channels is 4 Mbps per camera on average, right for 4 MP on H.265; with 4K cameras at 8 Mbps it still records only about 64.
- Gates, car parks and sites that track faces and plates — With Uniview smart cameras it receives up to 64 images/s from all channels, stores 3 million face and 3 million vehicle snapshot records, and holds up to 5 vehicle picture libraries with 25,000 pictures for plate watch lists.
- Integrators who plan to expand later — 2 extension slots take the FB-HD04-B-NB or FB-HD07-B-NB HDMI decoding cards (or the Smart Card for NVR-side analytics), 2 miniSAS ports connect the DEU1016-B 16-disk enclosure, and there is an eSATA port, so the box can grow with the project.
Where and how to install the recorder
- A deep 19-inch rack, on rails — The chassis is 3U, 482 × 533 × 131 mm and up to 12.5 kg without disks, heavier than the NVR516 models. Mount it on the SL-A slide rails in a cabinet deep enough for 533 mm plus cables, so it can slide out to fit extension cards or a power module.
- Room at or below 40 °C for 24 TB disks — The recorder runs from -10 °C to 55 °C, but the datasheet allows 24 TB disks only where the room does not exceed 40 °C. Use an air-conditioned room, keep vents clear, and turn on the High CPU Temperature and High Motherboard Temperature alerts so overheating is reported before disks suffer.
- Second power module and UPS — Input is AC 100–240 V with a power switch; for redundancy add the optional PWR-DC12-350A-IN (350 W) module and feed the two modules from different circuits or UPS units. Consumption is ≤ 65 W without disks; size the UPS for the recorder with 16 disks and any extension cards, plus the PoE switches.
- Four Gigabit ports, no SFP or PoE — There are 4 RJ45 Gigabit ports. The 512 Mbps input fits in one Gigabit (1000 Mbps) link, so use one port for the camera network and another for operators and the Internet. Cameras connect to PoE switches (copper up to 100 m per run); buildings farther away come in over fibre to a core switch, then copper to the recorder.
- Disks, RAID and expansion — Fit 16 identical 3.5-inch SATA surveillance-grade disks (up to 24 TB each) and build the RAID array before cameras record; RAID 6 is the safe choice with large disks. Keep spare disks of the same model on site, and if more storage is needed later, add the DEU1016-B enclosure on the miniSAS ports rather than mixing disk sizes in one array.
- Alarms and screens — Wire door contacts and beams to the 24 alarm inputs and sirens or relays to the 8 outputs, using the 12 V output for small devices. HDMI1, HDMI2 (up to 4K) and VGA are independent; VGA live video is output by default, so clear the VGA video on the preview page to get full 4K on HDMI.
Planning table: channels, bandwidth, disks, RAID and retention
Both models share the 512 Mbps input, 16 bays of up to 24 TB, decoder, outputs, extension slots and ports; only the channel count differs. On the NVR816-64 every channel can use 8 Mbps (full 4K), on the NVR816-128 the average drops to 4 Mbps. With 4K cameras both stop at about 64, so the 128-ch pays off only with 2–4 MP cameras.

| IP camera channels | 64 | 128 |
| Incoming bandwidth | 512 Mbps | 512 Mbps |
| Average bitrate per camera with every channel in use | 8 Mbps | 4 Mbps |
| Cameras at 8 Mbps (typical 4K H.265) within the bandwidth | 64 (all channels) | 64 |

| Power supply | AC 100–240 V; 2nd module optional (PWR-DC12-350A-IN) | AC 100–240 V; 2nd module optional (PWR-DC12-350A-IN) |
| Days on RAID 6 (336 TB), every channel at 4 Mbps | 121.5 (64 cameras) | 60.8 (128 cameras) |
| Days on RAID 6 (336 TB), 4K cameras at 8 Mbps | 60.8 (64 cameras) | 60.8 (64 cameras, bandwidth limit) |
- Pick the NVR816-64 for up to 64 cameras when many or all are 4K/8 MP: 64 × 8 Mbps = 512 Mbps, exactly the input limit.
- Pick the NVR816-128 for 65–128 cameras of 2–4 MP at about 4 Mbps each.
- If you need ONVIF third-party cameras or analytics on ordinary cameras without an extra card, compare the NVR816-64-R-IM-4G / NVR816-128-R-IM-8G, whose datasheet states both.
Assumptions: continuous 24-hour recording, 4 Mbps per 4 MP camera and 8 Mbps per 4K camera (typical H.265 main streams), decimal terabytes. Days = usable TB × 10^12 ÷ (cameras × bitrate ÷ 8 × 86,400). RAID 5 usable = 15 × 24 TB, RAID 6 usable = 14 × 24 TB; formatted capacity is slightly lower. 24 TB disks require a room at or below 40 °C; with 16 TB disks every figure scales by 2/3.
