Dahua DHI-NVR4104HS-P-AI/ANZ 4 Channel 4PoE Wizsense Network Video Recorder

Model: DHI-NVR4104HS-P-AI/ANZ

Who This Is For

Property managers specifying a compact, AI-capable recorder for small-site deployments will find the Dahua NVR4104HS-P-AI/ANZ a practical fit. Designed for 4-camera systems, it suits retail shopfronts, small offices, childcare facilities, and residential properties where every camera position matters and intelligent filtering genuinely reduces the burden of reviewing false alarms. The built-in WizSense AI handles face detection, face recognition, perimeter protection, and SMD Plus directly at the recorder level - meaning you do not need to purchase AI-capable cameras to access basic intelligent alerting. Four integrated PoE ports mean a single network cable delivers both power and data to each camera, keeping installation clean and cabling costs down. For sites already running WizSense cameras, the NVR also passes through more advanced AI functions including ANPR, people counting, heat map, and stereo analysis, making it a capable foundation that can grow with the site over time.

What This NVR Actually Does

Who Buys This Model

• Small retail and hospitality operators: Businesses running 2-4 cameras who want SMD Plus to stop chasing false motion alerts after hours, without paying for a full commercial NVR.
• Security installers on residential builds: Integrators fitting out homes with up to 4 WizSense cameras who want a single compact unit providing PoE power, recording, and AI filtering from one device.
• Childcare and small office facilities: Sites that need face detection and perimeter protection at the recorder level to meet duty-of-care obligations without requiring specialist AI cameras at every position.
• Property managers upgrading from analogue DVRs: Managers transitioning to IP who want a straightforward 4-channel IP recorder with integrated PoE, ONVIF compatibility, and a familiar local GUI without complex network configuration.

Honest Assessment

The NVR4104HS-P-AI/ANZ does a specific job well: it brings AI-level event filtering and intelligent search to a compact, 4-channel PoE system at a price point that suits small sites. The SMD Plus filtering across all 4 channels, combined with AI by Recorder for face detection and perimeter protection, meaningfully reduces alarm fatigue without requiring a premium AI camera at every position. Smart H.265+ compression and up to 8MP support make it genuinely future-compatible for 4K camera upgrades. It is available through Security Australia as part of a broader Dahua WizSense ecosystem.

Where this unit will not serve you: if you need more than 4 camera positions now or have likely expansion beyond that, a higher-channel NVR is the correct starting point. The single HDD bay also limits onboard storage capacity, so sites with long retention requirements - 30-plus days at high resolution across all 4 channels - should plan for a larger-capacity drive or factor in a higher-channel model with dual HDD bays. This is not a unit designed for multi-site central monitoring or VMS integration at scale.

Before You Buy

Quick Fit Check

• Good match if: You are installing a 2-4 camera IP system and want intelligent SMD Plus filtering and perimeter protection without purchasing premium AI cameras at every position.
• Good match if: Your installation requires a single compact unit that powers cameras over PoE, records up to 8MP, and provides remote access via DMSS - with no separate switch or power supply needed.
• You may need a different model if: You need more than 4 camera channels now or anticipate site expansion - a higher-channel NVR with dual HDD bays will better serve growing or multi-zone installations.

Real-World Scenarios

How It Compares

• Choose this if: You need a compact 4-channel PoE recorder with onboard AI - face detection, perimeter protection, and SMD Plus - without paying for a higher-channel NVR you will not fully use.
• You may need a different model if: You need more than 4 channels, dual HDD bays for longer retention, or centralised monitoring across multiple sites - an 8-channel or higher NVR with expanded storage support is the more appropriate product type.
• Pairs well with: Dahua WizSense turret or bullet cameras in the 4-8MP range, and a compatible surveillance-grade HDD sized for your retention requirements.

Common Questions

1. Does this NVR work with non-Dahua cameras?

   Yes. The NVR4104HS-P-AI/ANZ supports ONVIF-compliant cameras and custom protocols, so third-party IP cameras can connect for standard recording. However, AI by Recorder features - face detection, perimeter protection, and SMD Plus - require Dahua WizSense cameras to function as intended. Third-party cameras will record video but will not pass through AI event data to the NVR's intelligent search and alert functions.

2. Will this NVR run perimeter protection on all 4 cameras at once?

   Not via the NVR's own AI. AI by Recorder supports perimeter protection on 2 channels simultaneously, with up to 10 IVS rules per channel. If you need perimeter protection active across all 4 channels at the same time, you will need WizSense cameras that process perimeter protection onboard - the NVR then receives and displays those AI events from all 4 channels without the 2-channel restriction applying.

3. How much storage do I need for this NVR?

   It depends on camera resolution, frame rate, and how many days of footage you need to retain. As a practical guide, 4 cameras recording at 4MP using Smart H.265+ compression typically requires around 2TB for 30 days of continuous recording. At 8MP across all 4 channels, plan for 4TB or more. The NVR accepts one HDD - not included - so factor in capacity before purchase and use a surveillance-rated drive rather than a desktop drive.

4. Does this NVR support ANPR (licence plate recognition)?

   Yes, but only via AI by Camera - not the NVR's own processor. The NVR does not perform ANPR itself. When a compatible Dahua ANPR camera is connected, the camera processes the plate data onboard and sends the results to the NVR, which logs and displays the information and supports blocklist/allowlist searching. The NVR acts as the storage and management layer; the camera does the ANPR processing. This distinction is important when selecting cameras for a carpark or driveway application. The NVR4104HS-P-AI/ANZ is stocked by Security Australia alongside compatible Dahua ANPR cameras.

5. What is the face database capacity and how does face recognition work on this unit?

   The NVR supports up to 10 separate face databases holding a combined total of 20,000 face images. Face recognition at the recorder level operates on 1 channel - the NVR captures faces from that camera feed, extracts feature data using a deep learning algorithm, and compares the result against enrolled faces in the database. Matches or non-matches can trigger alerts. For multi-channel face recognition across all 4 cameras simultaneously, WizSense cameras with onboard face recognition are required, with the NVR aggregating their results.

6. Can I access this NVR remotely without a static IP address?

   Yes. The DMSS app supports P2P (peer-to-peer) connection, which means you can access live view, playback, and push alerts on a mobile device without configuring port forwarding or requiring a static IP at the installation site. A standard broadband connection at the site and the NVR's serial number are sufficient to establish a remote connection through the DMSS app on iOS or Android.

7. What is the difference between SMD Plus via the NVR and SMD Plus via the camera?

   Both filter motion events to human and vehicle targets using deep learning, but they operate differently. AI by Recorder SMD Plus runs on the NVR's processor and analyses video from the connected cameras in real time - processing load is handled by the NVR across all 4 channels. AI by Camera SMD Plus is processed onboard each compatible WizSense camera before the stream reaches the NVR, reducing the processing demand on the recorder and allowing more precise event metadata to be embedded in the stream. For sites using standard IP cameras without onboard AI, the NVR's SMD Plus still provides meaningful filtering. For maximum accuracy and channel scalability, camera-level SMD Plus is the more robust approach.
