Product SKU: DH-IPC-HDW3641EM-AS-KIT-NOHDD
Product Overview
The Dahua 4-camera WizSense 6MP turret kit delivers a complete, plug-and-play IP surveillance solution for homes, small businesses, and light commercial properties across Australia. Each DH-IPC-HDW3641EM-AS turret camera captures crisp 6MP footage at 3072 × 1728 resolution, with built-in infrared illumination reaching up to 30 metres in complete darkness. Powered over a single Ethernet cable via PoE, the cameras connect directly to the included 4-channel NVR for a clean, cable-efficient installation. Dahua’s WizSense AI platform drives Smart Motion Detection Plus (SMD+), which accurately filters humans and vehicles from irrelevant movement like animals or swaying foliage, dramatically reducing nuisance alerts. With a built-in microphone on every camera, IP67 weatherproofing, and support for up to 256GB microSD local backup, this kit offers serious capability at an accessible price point. Note: no hard drive is included — storage can be added separately.

Key Capabilities
6MP WizSense Resolution
At 3072 × 1728, each camera captures fine detail such as facial features and licence plates that standard 2MP or 4MP cameras can miss. The 1/2.7″ progressive scan CMOS sensor maintains image clarity even in low-light conditions, giving you actionable footage when it matters most.
SMD Plus — Human & Vehicle Detection
Dahua’s Smart Motion Detection Plus uses deep learning to distinguish humans and vehicles from other motion sources. This dramatically cuts down on false alarm notifications from animals, insects, or wind-blown objects, so every alert you receive is genuinely worth your attention.
30m Infrared Night Vision
Built-in IR LEDs illuminate scenes up to 30 metres away in total darkness, producing clear monochrome footage without any external lighting required. This extended range is well suited to driveways, car parks, and larger outdoor areas where coverage distance is a priority.
PoE — Single Cable Installation
Power over Ethernet means each camera receives both data and power through a single Cat6 cable connected to the NVR. This eliminates the need for separate power supplies at each camera location, simplifying installation considerably and reducing overall cable runs and cost.
Built-in Microphone & Audio Detection
Each camera features an integrated microphone for on-site audio capture and detection. Audio abnormality alerts can be configured to trigger notifications, adding an extra layer of situational awareness beyond what video alone can provide — particularly useful in retail or access-controlled environments.
Perimeter Protection & Tripwire
Intelligent detection features including tripwire and intrusion zone alerts allow you to draw virtual boundaries on the NVR interface. When those boundaries are crossed, the system triggers immediate push notifications to your phone, enabling rapid response without constant manual monitoring.
Best For
- Residential Properties: Four cameras provide comprehensive coverage of a typical home’s entry points, driveway, backyard, and side access gates with AI-filtered alerts to avoid constant nuisance notifications.
- Small Retail & Office Premises: The SMD+ system and perimeter protection features help business owners monitor entrances and car parks after hours, with push notifications sent directly to a smartphone.
- Rental Property Owners: A self-contained PoE kit with local NVR storage is ideal for landlords who want a reliable, low-maintenance system that does not depend on a third-party cloud subscription.
- Installers & Integrators: The WizSense platform, PoE architecture, and H.265+ compression make this kit efficient to deploy and manage across multiple sites without specialist configuration tools.
- Properties with Challenging Lighting: Wide Dynamic Range (WDR), 3D DNR, HLC, and BLC ensure usable footage in environments with mixed lighting such as covered car parks, shopfronts, or areas near bright artificial lighting.
Why Choose the Dahua 4-Camera WizSense 6MP Turret Kit
Budget IP camera kits often use generic motion detection that triggers on any pixel change — meaning your phone buzzes every time a leaf moves or a cat walks past. The Dahua WizSense 6MP turret kit takes a fundamentally different approach. Its SMD+ AI engine is trained specifically to identify the shape and movement patterns of humans and vehicles, so the alerts you receive are genuinely relevant. Paired with 6MP resolution, you get footage that holds up to digital zoom during an incident review — something that 2MP systems simply cannot match. H.265+ compression keeps file sizes manageable without sacrificing image quality, stretching your storage further. The integrated PoE NVR simplifies deployment by combining recording, power distribution, and remote access into a single unit. Security Wholesalers stocks this kit as a complete solution, allowing buyers to add a suitable hard drive at checkout and get started quickly without sourcing components separately.
Package Inclusions
- 1 x DHI-NVR4104HS-P-4KS2/L 4-Channel Compact 1U 4PoE 4K H.265 Lite Network Video Recorder (No HDD)

Buyer Decision Tips
Buyer Tip: This kit does not include a hard drive. Before purchasing, calculate your required storage based on the number of cameras, recording resolution, and how many days of footage you wish to retain. At 6MP with H.265+ compression across 4 cameras, a 4TB surveillance-grade HDD typically provides around 20–30 days of continuous recording — select a WD Purple or Seagate Skyhawk drive from the add-on options to complete your system.
Buyer Tip: The 2.8mm lens included with each DH-IPC-HDW3641EM-AS camera provides a wide field of view, making it ideal for covering large open areas such as driveways, car parks, and yards. If you need tighter coverage of a specific distant target — such as a gate entry point 15+ metres away — consider a version with a longer focal length lens instead.

FAQs
- Does this kit include a hard drive?
No — this kit is supplied without a hard drive, which is reflected in the product name and SKU. You can add a compatible surveillance-grade HDD (WD Purple or Seagate Skyhawk) directly from the product page. The NVR supports standard 3.5″ SATA drives, and capacity options ranging from 2TB to 8TB are available as add-ons depending on your storage requirements. - What is SMD Plus and how does it reduce false alarms?
SMD Plus (Smart Motion Detection Plus) is Dahua’s deep learning-based detection engine that analyses moving objects and classifies them as either human, vehicle, or other. Only human and vehicle detections trigger push notifications, so motion from animals, insects, wind, or shadows is automatically filtered out. This makes the alert system practical for daily use without requiring constant manual tuning. - Can I access the cameras remotely on my phone?
Yes. The NVR supports remote access via Dahua’s DMSS mobile application, available for both iOS and Android. Once the NVR is connected to your local network, you can view live feeds, play back recorded footage, and receive push notifications for SMD+, tripwire, and intrusion events from anywhere with an internet connection. - What does the 2.8mm lens cover and is it suitable for my property?
A 2.8mm fixed lens delivers a wide field of view — typically around 100–110 degrees horizontal — making it well suited to covering large open areas such as driveways, yards, and shopfronts at close to medium range. If you need to monitor a specific point from a greater distance, a longer focal length such as 3.6mm or 6mm may be more appropriate. - How does PoE work in this system?
Power over Ethernet allows the NVR to deliver both electrical power and network data to each camera through a single Cat6 cable. There are no separate power adapters or power points required at each camera location. The included NVR has four built-in PoE ports, one for each camera, making installation straightforward and cable-efficient. - Can the cameras record locally without the NVR?
Yes. Each DH-IPC-HDW3641EM-AS camera supports a microSD card of up to 256GB for independent local storage. This provides a useful backup in the event of NVR failure or network disruption, ensuring footage is still captured at the camera level even if the primary recording system is offline. - Is this kit compatible with other Dahua cameras or NVRs I already own?
The DH-IPC-HDW3641EM-AS cameras use standard ONVIF and Dahua protocols and are compatible with other Dahua NVRs that support 6MP IP cameras. If you are expanding an existing Dahua system, Security Wholesalers can help you identify compatible NVR models based on your current setup and camera count requirements. - What weatherproofing rating do the cameras carry?
Each camera is rated IP67, meaning it is fully protected against dust ingress and can withstand immersion in water up to one metre for 30 minutes. In practical terms, this makes the cameras suitable for exposed outdoor installation in Australian conditions including rain, humidity, and dust environments.
