Product description

Network video recorder (NVR) | 4 channels | 12 MP | 4K HDMI | 1 HDD up to 20 TB | H.265+ | SMD Plus | Dahua NVR4104HS-4KS3

The Dahua NVR4104HS-4KS3 is a 4-channel network video recorder from the Lite series (NVR4-4KS3). It accepts IP cameras up to 12 MP over the local network, records their video to one SATA drive and displays it on a monitor via HDMI or VGA.

Key point:
This is a professional Dahua recorder for a small system: 4 cameras, but no compromise on resolution – it accepts cameras up to 12 MP with 80 Mbps incoming bandwidth. SMD Plus on the recorder itself re-filters human and vehicle events, so your phone alerts you about people and cars, not leaves or rain.

Channels
4 IP channels

Max resolution
up to 12 MP per camera

Storage
1 × SATA up to 20 TB

Connectivity
RJ45 10/100 Mbps, ONVIF, P2P

Connectivity and integration

RJ45 10/100 Mbps – One network port: cameras and NVR connect via the same switch. The unit has no PoE ports, so cameras need a PoE switch or separate power supplies.
DMSS app (P2P) – Live view, playback and alerts on iOS and Android phones without a static IP address.
ONVIF 24.12 (Profile T/S/G) – You can connect not only Dahua but also third-party ONVIF cameras; check compatibility with a specific model before buying.
4K HDMI / VGA – Connect a monitor or TV directly: HDMI up to 3840 × 2160, VGA up to 1080p.
Browser and integration – Web interface (Chrome, Edge, Firefox, Safari), RTSP, CGI and SDK for VMS or other system integration.

How it works

Place the NVR in a dry cabinet or on a shelf, install a SATA drive (up to 20 TB), connect the 12 V DC 2 A power supply and an RJ45 cable to the same network as the cameras.

The NVR discovers the cameras on the network, receives their streams (up to 80 Mbps) and records according to the selected mode – continuous, motion or smart events. SMD Plus re-checks human and vehicle events on 4 channels.

You see live video on a monitor (HDMI up to 4K) and on your phone via DMSS, and find event recordings by time, tag or smart search.

Why choose the NVR4104HS-4KS3?
For a low price you get a Dahua platform with 12 MP channels, 20 TB of storage and ONVIF compatibility – a system that is easy to move or expand later, not a closed consumer solution.

SMD Plus on the recorder (4 ch) – secondary human and vehicle filter reduces false alarms from leaves, rain or light.
12 MP channels – suits both 4K and 12 MP cameras without a more expensive NVR.
Smart H.265+ – lower bitrate and a longer archive on the same drive.
AI camera events – with Dahua AI cameras: face detection and recognition, perimeter protection, people counting, heat map.
Smart search and playback – instant, event, tag and smart playback of up to 4 channels.
Alarm linkage – an event can trigger recording, snapshot, audio, buzzer, e-mail or an external output.
Backup – via USB storage or network.

How does it differ from similar models?

Hikvision DS-7604NXI-K1 (4 ch, €125.98) – also 4 IP channels, but the Hikvision ecosystem (Hik-Connect, AcuSense). Choose by camera brand.
Hikvision iDS-7216HUHI-M2/S(C) (DVR, €394.90) – hybrid: 16 analogue Turbo HD + IP channels, 2 HDDs. Suits upgrading old coax systems, not a new IP system.
IMOU NVR1104HS-W-S2 (4 ch, €74.12) – Wi-Fi NVR for homes with the IMOU Life app. Dahua offers wired networking, 12 MP channels and ONVIF.
IMOU NVR1108HS-W-S2 / NVR-N110W / N118W (8–18 ch) – more channels for a similar price, but aimed at IMOU Wi-Fi cameras at home.

Where is it used?

Private house with 2–4 PoE IP cameras
Small shop or café
Garage, warehouse or workshop
Yard and driveway with 4K / 12 MP cameras
Small office or dental clinic
Country house or cottage with remote viewing
Replacing an old analogue system with IP

Use by need

For installers working with Dahua cameras.
Familiar Dahua interface, DMSS and AI camera events without extra configuration.

For buyers who need sharp video of the yard.
12 MP channels let you upgrade cameras to higher resolution later without a new NVR.

For small businesses on a tight budget.
4 channels and one drive up to 20 TB – a full archive at the lowest price among wired NVRs in the group.

Practical use

If a garage with a driveway needs four cameras and you only want alerts about people or vehicles, connect 4 IP cameras through a 4-port PoE switch to the NVR4104HS-4KS3, install a 4–8 TB drive and enable SMD Plus on all 4 channels: recordings are stored in H.265+, and DMSS on your phone alerts you only to filtered events.

Pros

Accepts cameras up to 12 MP
1 SATA drive up to 20 TB
SMD Plus on the recorder for all 4 channels
HDMI up to 4K and VGA simultaneously
ONVIF 24.12 and broad third-party camera support
Low power: < 10 W without a drive
Compact 1U housing, 0.81 kg

Cons / limitations

No PoE ports – a PoE switch is needed (PoE version: NVR4104HS-P-4KS3).
Only 4 channels; for a larger system choose an 8- or 16-channel NVR from our Hikvision range.
10/100 Mbps network port – enough for 4 cameras, but not for fast copying of large archives over the network.
Face recognition, perimeter protection and people counting work only with AI cameras.
With AI enabled, fewer high-resolution channels can be decoded simultaneously.

Safety and installation notes

Place the NVR in a dry, ventilated location away from heat sources; operating temperature -10…+55 °C.
Install the drive only with the power disconnected.
A UPS and surge protection are recommended – sudden power loss can damage the drive or recordings.
Change the default password, update the firmware regularly and use P2P only with a strong password.
GDPR: set a recording retention period, restrict access and mark the monitored area with a sign.

Quick selection guide

4 IP channels

up to 12 MP

1 HDD up to 20 TB

no PoE

Suitable when you need:

a 2–4 IP camera system with a professional NVR
high-resolution (4K–12 MP) cameras
alerts only about people and vehicles

Check before use:

whether you have a PoE switch or camera power supplies
whether an HDD is included and what capacity you need
whether your cameras support ONVIF or are Dahua

Important reminder: The NVR does not power the cameras and is not an alarm system – it records, filters and displays video.

FAQ

Can I connect non-Dahua cameras?
Yes, via ONVIF (Profile T/S/G); check compatibility with the specific model before buying.

What size drive can I install?
One SATA drive up to 20 TB.

Does the NVR power cameras via PoE?
No, this model has no PoE ports – use a PoE switch or the PoE version NVR4104HS-P-4KS3.

What is the maximum camera resolution?
Up to 12 MP per channel.

How do I view video on my phone?
With the free DMSS app (iOS / Android) over P2P.
