Rule of thumb: count your cameras, then match the built-in PoE ports. The 04LS3-P4 has 4 PoE ports for 4 cameras and the 08LS3-P8 has 8 PoE ports for 8 cameras — both fully self-powered. The 16LS3-P8 records 16 channels, but its built-in PoE only covers the first 8; the other 8 cameras need independent power or an extra PoE switch. Highlighted rows in the spec table below show every difference between the three.

The Uniview NVR301-LS3-P Series is a 1-HDD PoE network video recorder offered in three sizes: NVR301-04LS3-P4 (4-ch, 4 built-in PoE ports), NVR301-08LS3-P8 (8-ch, 8 built-in PoE ports) and NVR301-16LS3-P8 (16-ch, 8 built-in PoE ports). All three record cameras up to 8MP with Ultra 265 / H.265 / H.264 compression and output simultaneously over 4K HDMI and VGA. One SATA bay takes a hard disk up to 10 TB; the local interface is available in 21 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.
Small shops & homesThe 4-ch 04LS3-P4 ships with 4 built-in PoE ports — plug in 4 PoE cameras directly, no separate power supply or switch needed.
Growing businessesBuy channels you don't use yet: the 08LS3-P8 gives 8 built-in PoE ports for 8 cameras; the 16LS3-P8 records 16 channels while its 8 PoE ports cover the first 8, leaving room to add 8 more independently-powered cameras later.
Save on cablingBuilt-in PoE carries power and video over one Ethernet cable per camera — up to 30 W per port, with a shared budget of 54 W total on the 04LS3-P4 and 75 W total on the 08LS3-P8 / 16LS3-P8, so you skip the separate PoE switch within that budget.
Remote viewing on phoneP2P protocol built in — the owner checks the shop from a phone app without a fixed IP or network skills.
Local-language interface21 GUI languages including Spanish (Latin America), Portuguese (Brazil) and French — your customer operates it in their own language.
Quick incident lookupFace Detection on up to 4 channels feeds Face Snapshot Search and Behavior Search — narrow hours of footage down to the clip you need.
Not the right pick if you need…
- Full PoE power for all 16 channels — the 16LS3-P8's 16 video channels share only 8 built-in PoE ports (max 75 W total); cameras on channels 9–16 need independent power or an extra PoE switch
- A second hard disk or RAID — this series has a single SATA bay
- Gigabit uplink — the network port is 10/100M (fine for 16 cameras at 64 Mbps total)
- Alarm in/out wiring for sirens or sensors — the external interface list has no dedicated alarm terminals
- Audio input — it has an RCA audio output only (camera-side mics still record)

Saves your disk. Skips the switch.
Two real capabilities from the datasheet that matter every day: storage efficiency and built-in camera power.
ULTRA 265
Half the storage, same image
Ultra 265 compression cuts recording size dramatically versus H.264 — on the same 10 TB disk you keep footage for weeks longer, or record more cameras at higher resolution.
BUILT-IN POE
Skip the separate PoE switch
Every port supports IEEE 802.3at / 802.3af, up to 30 W per port — the 04LS3-P4 has a 54 W total power budget, the 08LS3-P8 / 16LS3-P8 have 75 W total, enough to run a full set of PoE cameras straight off the recorder.

Who uses it, where it goes and how to install it
Written for the NVR301-04LS3-P4, 08LS3-P8 and 16LS3-P8 from the official datasheet: 4, 8 or 16 IP channels up to 8 MP, 4 or 8 built-in PoE ports (54 W or 75 W, 30 W per port), 64 Mbps incoming bandwidth, 1 SATA bay up to 10 TB, 4K HDMI plus VGA.
Which size suits which installation
- NVR301-04LS3-P4: small shops, kiosks and homes — The compact 205 × 205 × 46 mm body fits under a counter; 4 PoE ports with 54 W in total (13.5 W per port on average) power four cameras, even ones with white light, without a switch.
- NVR301-08LS3-P8: restaurants, offices, small yards — 8 cameras on 8 PoE ports and 75 W, with 8 Mbps per channel when all 8 are used: comfortable for 2–5 MP cameras, or 4K at moderate bitrates.
- NVR301-16LS3-P8: sites that start with 8 cameras and grow — 16 recording channels but 8 PoE ports: cameras 9–16 come in through a PoE switch on the LAN port. With 16 cameras the 64 Mbps input means 4 Mbps each, which suits 2–4 MP cameras.
- Budget projects that need simple recording — Recording, P2P phone viewing and 21 interface languages, with smart events taken from up to 4 Uniview smart cameras in total; for recorder-side AI on more channels, look at the B-P-IQ or B-LP-IQ series.
Where and how to install the recorder
- Centre of the cable runs — Cameras plug straight into the PoE ports, so place the recorder where every camera is within 100 m of Cat5e/Cat6 solid copper cable. Put any cable joint in a junction box, and use a PoE switch or extender near cameras that are farther away.
- Counter, shelf or cabinet, with airflow — The body is 205 or 270 × 205 × 46 mm and light (≤ 0.8 kg), so it fits a shelf or a small locked cabinet. The datasheet says the largest usable disk depends on room temperature, so keep the vents clear and avoid hot ceilings and direct sun; the PoE ports add up to 75 W of heat.
- Right adapter, plus a UPS — Use DC 48 V / 1.35 A for the 04LS3-P4 and DC 52 V / 1.8 A for the 08LS3-P8 and 16LS3-P8. The PoE cameras lose power whenever the recorder does, so a small UPS for the recorder, router and any extra PoE switch keeps everything recording through short outages.
- LAN port and channels 9–16 — The single 10/100 Mbps LAN port goes to the router for remote viewing; on the 16LS3-P8 it also carries cameras 9–16 from an external PoE switch. Keep the camera total within the 64 Mbps input and remember remote viewers share up to 48 Mbps outgoing through the same port.
- Disk and monitor — Fit one 3.5-inch SATA surveillance-grade disk of up to 10 TB before power-on. HDMI (up to 4K) and VGA work at the same time; the 2 USB 2.0 ports are for a mouse and for exporting clips to a USB drive.
Planning table: channels, bandwidth, disk and retention
All three share a 64 Mbps input, one SATA bay up to 10 TB and the same outputs. The 08LS3-P8 and 16LS3-P8 have identical PoE hardware (8 ports, 75 W); the 16LS3-P8 simply records 8 more cameras that are powered elsewhere, and with 16 cameras each gets only 4 Mbps of the input.

| Days on 10 TB, all channels at 4 Mbps | 57.9 | 28.9 | 14.5 |
- Pick the 04LS3-P4 for up to 4 cameras: 13.5 W per port on average and 16 Mbps per channel, enough for 8 MP cameras.
- Pick the 08LS3-P8 for 5–8 cameras of 2–5 MP, all powered from the recorder.
- Pick the 16LS3-P8 for 9–16 cameras of 2–4 MP, with an extra PoE switch for cameras 9–16; for 16 cameras above 4 Mbps each, choose a recorder with more incoming bandwidth.
Camera counts assume 13 W for a camera with strong white light or a small PTZ, within the 30 W per-port limit; ordinary fixed IR cameras (typically about 6 W) can use every port. Retention assumes continuous recording at 4 Mbps per camera: days = TB × 10^12 ÷ (cameras × 4,000,000 ÷ 8 × 86,400); on the 16LS3-P8, 16 cameras at 4 Mbps fill the full 64 Mbps, so 2–3 Mbps per camera leaves useful headroom.

4/8/16 Channel PoE NVR FAQ — NVR301-LS3-P
How many cameras can I connect and power?
The 04LS3-P4 records 4 channels with 4 PoE ports; the 08LS3-P8 records 8 channels with 8 PoE ports; the 16LS3-P8 records 16 channels with 8 PoE ports, so on the 16-channel model the other 8 cameras connect through your network switch.
What is the PoE power budget?
Every port supports IEEE 802.3at/af at up to 30W. The 04LS3-P4 has a 54W total budget and the 08LS3-P8 and 16LS3-P8 have 75W total — with typical fixed IP cameras drawing a few watts each, a full set of PoE-connected cameras fits comfortably.
What resolution does it record and display?
Recording goes up to 8MP (4K) per channel. The decoder handles 1×4K@30 or 4×5MP@25 for local display, HDMI output reaches 4K (3840×2160) at 30 Hz and VGA reaches 1920×1080 at 60 Hz. All channels play back synchronously on every model.
What hard drive capacity does it take?
One SATA bay accepts a surveillance hard drive up to 10 TB (maximum varies with ambient temperature and disk model). Ultra 265 compression cuts recording size dramatically versus H.264, so the 10 TB disk keeps footage for weeks longer or covers more high-resolution cameras.
Does it support face detection?
Yes, through the cameras: up to 4 channels of camera-side face detection, SIP and UMD feed Face Snapshot Search and Behavior Search on the recorder. General alarms also cover motion detection, human body detection, tampering, audio detection and video loss.
Is it compact enough for a small shop counter?
Yes. The 04LS3-P4 measures 205×205×46 mm at under 0.6 kg; the 08LS3-P8 and 16LS3-P8 measure 270×205×46 mm at under 0.8 kg. Power draw is under 9W without HDD, and operating range is -10 to 55 °C — fine for counters and small equipment cabinets.
Can I connect 8 MP (4K) cameras to all 16 channels of the NVR301-16LS3-P8?
Only at low bitrates. The 64 Mbps input divided by 16 is 4 Mbps per camera, about half of a typical 8 Mbps 4K stream, so in practice plan about 8 cameras at 4K (8 × 8 = 64 Mbps) or use 2–4 MP cameras on all 16. The decoder also shows only 1 × 4K@30 at full resolution at a time, so 4K detail is seen one camera full screen; multi-camera views use lower-resolution streams.
What is the difference between the NVR301-08LS3-P8 and the NVR301-08B-P8-IQ?
Both have 8 channels, 8 PoE ports and 75 W. The 08LS3-P8 is the simpler recorder: 64 Mbps input, cameras up to 8 MP, disks up to 10 TB, 21 languages and smart events only from cameras (4 channels in total). The 08B-P8-IQ adds 80 Mbps input, 12 MP recording, disks up to 24 TB, 38 languages, recorder-side face detection, SIP and UMD, a USB 3.0 port and two-way audio. Choose the LS3 for plain recording, the B-P-IQ when face search or AI on ordinary cameras matters.
Which hard drive should I use in the NVR301-LS3-P series, and how many days will 10 TB hold?
One 3.5-inch SATA surveillance-grade drive built for 24/7 writing, up to 10 TB; the datasheet notes the usable maximum also depends on room temperature, so keep the recorder cool. At 4 Mbps per camera, continuous, 10 TB holds about 57.9 days for 4 cameras, 28.9 days for 8 and 14.5 days for 16; a 4 TB drive holds 23.1, 11.6 and 5.8 days. Motion-based recording and Ultra 265 extend this.
Can I listen to camera audio or talk through the cameras on the NVR301-08LS3-P8?
Listening, yes: audio from cameras with a microphone is recorded (G.711A/G.711U) and can be played through the 1-ch RCA audio output or HDMI to a monitor with speakers. The recorder has no audio input and two-way audio is not listed in its datasheet, so talk-back from the recorder is not something to plan on; if you need to speak to visitors, tell us the camera model and we will check talk-back from the phone app, or consider the B-P-IQ series, which lists 1-ch two-way audio.
How many people can watch the NVR301-04LS3-P4 remotely, and how is the firmware updated?
Up to 128 remote users can log in, sharing a maximum of 48 Mbps outgoing; P2P lets the owner add it to the Uniview phone app without a fixed IP, and a PC can use a browser (IE10/11, Chrome 45+, Edge 79+, Firefox 52+). In practice the site's internet upload speed sets how many cameras can be watched smoothly, so remote users usually view sub-streams. Firmware supports cloud upgrade, so it can be updated over the internet.
