Choose your size — two models on this page
Rule of thumb: count your cameras, then leave room to grow — the 104E2-P4's 4 built-in PoE ports suit a small shop; pick the 108E2-P8 if you have (or may add) more cameras. Every PoE port supplies both power and video over one Ethernet cable, up to 30 W per port. Highlighted rows in the spec table below show every difference between the two.

The Uniarch E2-P Series is a 1-HDD PoE network video recorder offered in two sizes: NVR-104E2-P4 (4-ch) and NVR-108E2-P8 (8-ch), both recording cameras up to 8MP with Ultra 265 / H.265 / H.264 compression and 4K HDMI + VGA simultaneous output. The built-in PoE ports — 4 on the 104E2-P4, 8 on the 108E2-P8, IEEE 802.3af/at, max 30 W per port — power ONVIF-compliant cameras through the same cable that carries video, so no separate PoE switch is needed. One SATA bay takes a hard disk up to 8 TB.
Is this the right recorder for you?
Plain-language guide for buyers and installers — based only on what this recorder actually does.
Small shops & homesThe 4-ch 104E2-P4 has 4 built-in PoE ports — plug 4 ONVIF cameras straight into the recorder with one cable each, no separate PoE switch or power adapters to buy.
Growing businessesThe 108E2-P8 gives you 8 built-in PoE ports — buy the size you'll need next year, not just today, without adding a separate switch later.
Remote viewing on phoneP2P protocol built in — the owner checks the shop from a phone app without a fixed IP or network skills.
One cable per cameraEach PoE port (IEEE 802.3af/at, up to 30 W) carries power and video together — the installer runs one Ethernet cable instead of a separate power line.
Longer video retentionUltra 265 roughly halves file size versus H.264 — the same 8 TB disk keeps weeks more footage.
Mixed-brand projectsONVIF Profile S/G/T means existing third-party IP cameras keep working on the built-in PoE ports — no need to replace the whole site.
Not the right pick if you need…
- Full-channel smart alerts — VCA alarms via connected IP cameras (intrusion, cross line, area) cover channels 1–4 only, and trigger an alert with no snapshot image
- A second hard disk or RAID — this series has a single SATA bay
- Gigabit network — both the uplink and the built-in PoE ports are 10/100M (fine for 4/8 cameras at 40/50 Mbps total)
- Alarm in/out wiring for sirens or sensors
- Audio input — it has an RCA audio output only (camera-side mics still record via ONVIF)

Powers your cameras. Saves your disk.
The two capabilities that decide whether an entry PoE NVR feels cheap or smart.
PoE BUILT-IN
Power and video over one cable
4 ports on the 104E2-P4, 8 on the 108E2-P8 (IEEE 802.3af/at, max 30 W per port, 54 W / 75 W total budget) — plug an ONVIF camera straight into the recorder, no separate PoE switch or power adapter.
ULTRA 265
Half the storage, same image
Ultra 265 compression cuts recording size dramatically versus H.264 — on the same 8 TB disk you keep footage for weeks longer, or record more cameras at higher resolution.

Who uses it, where it goes and how to set it up
Written for the NVR-104E2-P4 and NVR-108E2-P8 from the official datasheet: 4 or 8 channels with the same number of built-in PoE ports (IEEE 802.3af/at, max 30 W per port, 54 W / 75 W total), 40 / 50 Mbps incoming bandwidth, 1 SATA HDD up to 8 TB, 4K HDMI + VGA.
Who it is for
- Small shops, offices and homes — The NVR-104E2-P4 powers 4 cameras directly from its PoE ports, so a complete system is recorder, disk, cables and cameras, with no switch or camera power adapters.
- Installers doing quick 8-camera jobs — The NVR-108E2-P8 has 8 PoE ports and a 75 W budget: 8 typical 4MP IR cameras at about 6 W each use 48 W, leaving margin for one or two higher-power cameras.
- Sites with existing third-party cameras — ONVIF Profile S, G and T are listed, and the ports follow IEEE 802.3af/at, so standard PoE cameras from other brands can be plugged in when the recorder is replaced.
- Owners who check from a phone — P2P is built in, up to 128 remote users are listed with 40 Mbps outgoing bandwidth, and the local interface comes in 21 languages including Spanish (Latin America), Portuguese (Brazil) and French.
Where and how to install
- Desk or cabinet, locked away — At 260 × 243 × 46 mm it fits a desk or a cabinet shelf near the monitor. Keep it in a locked room or cabinet so an intruder cannot take the recorder and the footage with it.
- Ventilation: PoE adds heat — Working range is -10 °C to 55 °C, ≤ 90% RH non-condensing. With up to 54 W or 75 W going out to cameras the box runs warmer than a non-PoE recorder, and the datasheet notes that maximum HDD capacity varies with temperature, so leave space around it and keep it out of sun and closed hot boxes.
- PoE cabling: 100 m per run — Run one Cat5e or Cat6 copper cable from each PoE port to each camera, no longer than 100 m. Put outdoor joints in a junction box, and add surge protection on long outdoor or pole runs.
- UPS and the power adapter — The cameras get their power from the recorder, so a power cut stops everything at once. Put the recorder's adapter (DC 48 V/1.35 A on the 104E2-P4, DC 52 V/1.8 A on the 108E2-P8) and the router on a UPS; this also protects the hard disk.
- Surveillance hard disk — Fit one SATA disk of up to 8 TB, preferably surveillance-grade for 24/7 writing, and format it in the NVR before recording. Connect the separate RJ45 10/100 Mbps network port to the router for the app and remote viewing.
Planning table: PoE budget, bandwidth, disk and days of recording
Any single port can give 30 W, but the total is capped at 54 W (104E2-P4) or 75 W (108E2-P8), so add up the cameras' maximum power. Incoming bandwidth is also a total: 40 or 50 Mbps shared by all channels. Retention assumes continuous recording on all channels and an 8 TB disk; 4 Mbps per camera is a typical 4MP H.265 stream, 2 Mbps a typical 2MP or Ultra 265 stream.

- Add up the cameras' maximum power from their datasheets, not the typical value, and stay under 54 W or 75 W; with IR or warm light on at night, cameras draw the most.
- A PTZ or heater camera that needs up to 30 W can use one port, but it leaves only 24 W (104E2-P4) or 45 W (108E2-P8) for all the other cameras.
- Keep the total bit rate under 40 or 50 Mbps, for example 8 cameras at 4 Mbps (32 Mbps) on the 108E2-P8.
Days = 8 TB × 10^12 ÷ (cameras × bit rate ÷ 8 × 86400), rounded down; one camera at 4 Mbps writes about 43.2 GB per day. The 6 W per 4MP IR camera used above is an assumed typical figure; always check each camera's own maximum power.

4/8 Channel PoE NVR FAQ — NVR-104E2-P4/108E2-P8
How many cameras can the PoE ports power?
The NVR-104E2-P4 has 4 PoE ports with a 54W total budget; the NVR-108E2-P8 has 8 ports with 75W total. Each port delivers up to 30W (IEEE 802.3af/at). Typical IP cameras draw well under these averages, so both models can power a full set of cameras directly.
Do I still need a separate PoE switch?
Not for a basic installation — plug ONVIF cameras straight into the recorder's PoE ports and they get power and video over one network cable. The uplink to your router is a separate 10/100M RJ45 port. The unit is powered by DC 48V/1.35A (P4) or DC 52V/1.8A (P8).
How many hard disks fit and what is the maximum size?
One SATA bay, up to 8 TB per surveillance hard drive (maximum capacity varies with ambient temperature). With Ultra 265 compression the same 8 TB disk keeps footage for weeks longer than H.264, or records more cameras at higher resolution on the same budget.
Can it record and display 4K cameras?
Yes. Recording resolution goes up to 8MP (4K), and the decoder handles 1×4K@30 or 4×5MP@25 for local display. The HDMI output reaches 4K (3840×2160) at 30 Hz, with VGA up to 1920×1080 also available for a second screen.
What is the difference between the 104E2-P4 and 108E2-P8?
Channel and PoE count: 4 channels with 4 PoE ports and 54W budget versus 8 channels with 8 ports and 75W. Incoming bandwidth is 40 Mbps on the P4 and 50 Mbps on the P8. Recording up to 8MP, one 8 TB HDD bay and the 260×243×46 mm case are the same.
Can I check the cameras remotely?
Yes. P2P, DDNS, HTTP/HTTPS and RTSP are supported, with up to 128 remote users and 40 Mbps of outgoing bandwidth for remote viewing. Browsers supported: Chrome 45+, Edge 79+, Firefox 52+ and IE10/11 via plugin.
Will Hikvision, Dahua or other non-Uniarch cameras work on the NVR-104E2-P4 / 108E2-P8 PoE ports?
Usually yes for video: the datasheet lists ONVIF Profile S, G and T, and the ports supply standard IEEE 802.3af/at PoE. The camera must have ONVIF enabled and accept 802.3af/at power, not a passive 12 V or 24 V PoE. Smart events such as intrusion or line crossing are listed as coming from the camera and may be limited with other brands, so send us the camera models and we will confirm before you order.
Can I mix Uniarch Uho Wi-Fi cameras with PoE cameras on the NVR-108E2-P8?
Often yes, but check the exact Uho model with us first: the NVR datasheet has no compatibility list and many Uho datasheets list API integration rather than ONVIF. A Wi-Fi camera reaches the NVR through the router and the NVR's separate RJ45 network port, not through a PoE port. Every camera, wired or Wi-Fi, uses one of the 8 channels, and a dual-lens Uho uses two.
One camera is more than 100 m from the NVR-104E2-P4. What can I do?
The PoE ports are 10/100 Mbps copper, and Ethernet copper is limited to 100 m per run, so do not simply use a longer cable. Use a PoE extender or a small PoE switch placed within 100 m of the camera, or a fibre link with media converters for long distances. Remember that a camera powered elsewhere still uses one of the recorder's channels.
How many days will the NVR-108E2-P8 record with 8 cameras on an 8 TB disk?
About 23 days of continuous recording at 4 Mbps per camera: one camera writes about 43.2 GB a day, so 8 cameras write about 346 GB a day. At 2 Mbps per camera it is about 46 days, and on the NVR-104E2-P4 with 4 cameras at 4 Mbps about 46 days. Motion or event recording and Ultra 265 on the cameras extend this.
Do intrusion and line-crossing alarms work on all 8 channels of the NVR-108E2-P8?
No. These smart events come from the cameras and the datasheet allows 4 channels in total: SIP (intrusion, cross line, enter area, leave area) works on channels 1–4 only and gives an alarm without a snapshot. Plug the cameras that watch the main gate, doors or fence into PoE ports 1–4 so they land on those channels. Ultra Motion Detection by the cameras and Behavior Search are also listed.
What size UPS do I need for the NVR-104E2-P4 or NVR-108E2-P8?
Size it for the adapter's rated output plus the router: DC 48 V × 1.35 A is about 65 W on the 104E2-P4 and DC 52 V × 1.8 A is about 94 W on the 108E2-P8, which already includes the cameras powered over PoE (54 W / 75 W budget) and the recorder itself (≤ 9 W without the disk). A small line-interactive UPS of a few hundred VA is a common choice; runtime depends on its battery. Without a UPS, a cut switches off the recorder and every PoE camera together.
