Product SKU: DH-3X66-K8044T-W-2TB
Product Overview
Combining 8MP WizSense turret cameras with an AI-capable PoE NVR, the DH-3X66-K8044T-W-2TB is a ready-to-deploy 4-camera IP surveillance kit suited to residential properties and small commercial sites. Each of the 4 included DH-IPC-HDW3866EMP-S-AUS turret cameras captures footage at 3840 x 2160 resolution using a 2.8mm fixed lens, with Starlight low-light imaging and 30m IR providing detail in near-dark conditions. Featuring SMD Plus 4.0, the system classifies motion events as human or vehicle rather than responding to every trigger, which significantly cuts down on unnecessary alerts. The included DHI-NVR4104HS-P-AI/ANZ NVR provides 4 built-in PoE ports to power all cameras over a single Cat6 cable per run, and comes with a 2TB surveillance-grade hard drive pre-installed. It is well suited to new builds, upgrade projects, and any site where a clean, single-cable PoE installation is preferred over a mixed-power setup.


Key Capabilities
8MP 4K Resolution Across All 4 Cameras
Each DH-IPC-HDW3866EMP-S-AUS camera outputs 3840 x 2160 at up to 30fps via a 1/2.8″ CMOS sensor. The level of detail captured at this resolution allows faces, clothing, and vehicle details to be identified at typical driveway and entry-point distances.
Starlight Low-Light Imaging
Starlight technology produces colour-rich images in near-darkness before switching to IR illumination. Built-in IR LEDs extend effective coverage to 30m, ensuring usable footage at night even in poorly lit driveways, car parks, and building perimeters.
SMD Plus 4.0 Human and Vehicle Classification
Smart Motion Detection 4.0 uses deep learning to distinguish humans and vehicles from background motion such as animals, insects, and foliage movement. This means motion alerts on the NVR and mobile app correspond to events that actually warrant attention.
AI NVR with Perimeter Analytics
The DHI-NVR4104HS-P-AI/ANZ supports intrusion detection and tripwire analytics across up to 2 channels simultaneously, with human and vehicle classification applied to trigger events. Face detection and recognition is available on 1 channel, with AI processing distributed across the NVR and connected cameras.
4-Port PoE for Clean Single-Cable Runs
All 4 cameras are powered and connected via the NVR’s built-in PoE ports over individual Cat6 cables. No separate power supplies or injectors are required at each camera location, which simplifies installation and reduces the number of components needed at each mounting point.
H.265+ Compression with Pre-Installed 2TB Storage
H.265+ reduces file sizes substantially compared to standard H.264, maximising the retention capacity of the included 2TB surveillance-grade hard drive. The NVR handles up to 80 Mbps for access, storage, and forwarding, with a 4K HDMI output for direct monitor connection.
Best For
- Residential Perimeter Coverage: Covers up to 4 access points including front entry, driveway, side gate, and backyard with 4K resolution and night vision capable of capturing identifiable detail in low-light conditions.
- Small Commercial Premises: Suited to retail shops and small warehouses requiring AI-filtered perimeter protection with tripwire and intrusion detection across up to 2 channels on the NVR.
- PoE Installations and New Builds: Ideal for sites where Cat6 cabling is being installed during construction or renovation, allowing a single clean cable run per camera from a central NVR location.
- Low-Light Monitoring Environments: Well suited to locations with minimal overnight lighting where Starlight technology and 30m IR range are required to maintain usable image quality through the night.
- Analogue CCTV Replacements: A practical upgrade path for sites moving from DVR-based analogue systems to an IP platform with 4K resolution, smart analytics, and P2P mobile viewing.
Why Choose the DH-3X66-K8044T-W-2TB
Where a basic 2MP or 5MP PoE kit records movement, the DH-3X66-K8044T-W-2TB records and classifies it. The WizSense AI engine operates at both the camera and NVR level, meaning SMD Plus 4.0 filtering, tripwire, and intrusion detection are active from the moment the system is set up. The 8MP sensor on each DH-IPC-HDW3866EMP-S-AUS camera provides enough pixel density to identify individuals and vehicles at the distances typical of residential driveways and commercial entry points. The 120dB WDR rating handles scenes with mixed lighting that would cause cheaper cameras to lose detail in highlights or shadows. The 2TB hard drive arrives pre-installed in the DHI-NVR4104HS-P-AI/ANZ, removing the need for a separate storage purchase at commissioning. Security Wholesalers supplies this kit as a complete package with cameras, NVR, and pre-installed storage, making it straightforward to purchase and deploy.
Package Inclusions

- 1 x 4ch DHI-NVR4104HS-P-AI/ANZ – 2TB
Buyer Decision Tips
Buyer Tip: The pre-installed 2TB hard drive will handle continuous recording at 8MP across 4 cameras, but retention time is reduced at higher frame rates. If your site requires extended footage retention beyond a few days at full resolution, plan for a larger surveillance-grade hard drive at the time of purchase. Retrofitting storage requires reopening the NVR unit, so it is more cost-effective to size the HDD correctly from the start.
Buyer Tip: The DHI-NVR4104HS-P-AI/ANZ supports exactly 4 PoE channels and cannot be expanded. If there is any chance you will need more than 4 camera positions within the next few years, run conduit and pull cable for those additional positions during the initial installation. Adding cable pathways after walls and ceilings are finished is significantly more difficult and expensive than planning ahead.

Ideal Use Cases
Residential Perimeter Monitoring
Covers 4 key access points of a typical home with 8MP resolution and Starlight night vision. The 2.8mm wide-angle lens provides broad scene coverage at each position, while SMD Plus 4.0 ensures notifications reflect genuine human or vehicle activity.
Retail Shop Surveillance
AI-filtered motion detection reduces alert fatigue in customer-facing and stockroom areas. The 8MP resolution supports incident review and documentation at a level that a 2MP or 4MP camera cannot match in identifying individuals or reading labels.
Small Warehouse and Workshop Monitoring
Tripwire and intrusion detection on the DHI-NVR4104HS-P-AI/ANZ make this kit practical for after-hours monitoring of industrial sites where separating vehicle arrivals from pedestrian activity is important for incident management.
Driveways and Car Parks
The combination of a 2.8mm wide-angle lens and 8MP sensor provides broad scene coverage with enough pixel detail for vehicle identification. SMD Plus classifies vehicle motion separately from pedestrian movement to reduce irrelevant alert events.
New Build and Renovation Projects
The PoE architecture fits naturally into new construction where Cat6 cabling is being installed as part of the build. A single cable per camera simplifies conduit planning and avoids the need for separate power points at each mounting location.
Analogue System Replacement
Sites replacing ageing DVR and analogue camera setups gain a substantial uplift in resolution, smart analytics, and remote access capability by migrating to this IP-based WizSense kit. The pre-installed 2TB hard drive ensures the system is operational without additional procurement steps.
Choosing the Right Model
- Choose this model if: You need a complete out-of-the-box 4-camera IP system with 8MP resolution, AI human and vehicle classification at both camera and NVR level, Starlight low-light performance, and a pre-installed 2TB hard drive in a single PoE-powered package.
- Choose a different model if: Your site requires more than 4 camera positions, a varifocal or motorised zoom lens for adjustable framing, or a higher base storage capacity as the standard configuration. In those cases, a larger channel NVR kit or a higher-capacity HDD bundle would be a more appropriate starting point.
FAQs
- Does the 2TB hard drive come pre-installed in the NVR?
Yes. The 2TB surveillance-grade hard drive is pre-installed in the DHI-NVR4104HS-P-AI/ANZ before dispatch. Once cameras are connected via the PoE ports and initial setup is completed through the NVR’s on-screen interface or mobile application, the system is ready to record without any additional storage configuration. - How many cameras can this NVR support?
The DHI-NVR4104HS-P-AI/ANZ supports exactly 4 channels and includes 4 built-in PoE ports. It cannot be expanded beyond 4 connected cameras. If your site is likely to require additional coverage points in the future, upgrading to a higher-channel NVR at the time of initial installation is a more cost-effective approach than replacing the recorder later. - What cable is needed to connect the cameras to the NVR?
Each camera connects to one of the NVR’s PoE ports via a single Cat6 cable, which carries both data and power. Maximum recommended PoE cable distance is 100m per run. Pre-terminated Cat6 cables in various lengths are available separately to suit different installation layouts. - How does SMD Plus 4.0 differ from standard motion detection?
Standard motion detection triggers on any pixel change in the scene, including animals, passing headlights, blowing foliage, and insects near the lens. SMD Plus 4.0 uses deep learning at the camera level to classify detected objects as human or vehicle before generating an alert. This means motion events recorded and notified by the system correspond to activity that is actually relevant to security monitoring. - Are the cameras suitable for permanent outdoor installation?
Yes. Each DH-IPC-HDW3866EMP-S-AUS carries an IP67 ingress protection rating, confirming it is sealed against dust and protected against water jets from any direction. This makes the cameras appropriate for permanent exterior mounting on eaves, soffits, and external walls where they are exposed to weather year-round. - Can I view the cameras remotely from my phone?
Yes. The DHI-NVR4104HS-P-AI/ANZ supports P2P remote access through the Dahua mobile application, allowing live viewing and footage playback over a standard internet connection. This does not typically require manual port-forwarding configuration on your router. - What is the IR range of the cameras at night?
The built-in IR LEDs on each DH-IPC-HDW3866EMP-S-AUS provide effective illumination to a maximum distance of 30m. Starlight technology also maintains colour detail in low-ambient-light conditions before the IR mode is engaged, which can be useful in partially lit environments such as driveways with street lighting nearby. - Where can I purchase this kit and get support?
This kit is available through Security Wholesalers, which carries the full Dahua WizSense range along with compatible accessories including surveillance-grade hard drives in larger capacities, mounting brackets, waterproof junction boxes, and Cat6 cabling to support complete installations from a single supplier.
Cabling Considerations
- Cable Type: Cat6 unshielded or shielded twisted pair (UTP/STP) is recommended for all camera-to-NVR runs. A single Cat6 cable per camera carries both the data stream and PoE power supply.
- Maximum Cable Run: Maximum PoE cable distance is 100m per camera from the NVR PoE port. Runs exceeding this length will result in degraded or lost PoE power delivery and potential data signal issues.
- PoE Considerations: All 4 cameras draw power directly from the NVR’s built-in PoE ports. No separate power injectors, switches, or adaptors are required as long as cable runs remain within the 100m limit.
- Wiring Tips: Route cables through conduit where exposed to UV, physical impact, or rodent activity. Use a waterproof junction box at each camera mounting point to protect rear cable connections from moisture ingress, particularly on exterior eave and soffit installations.
