Combining active deterrence with full-colour night vision and a motorised varifocal lens, the Dahua IPC-HDW3849H-ZAS-PV-ANZ-S2 is an 8MP TiOC turret camera built for sites where passive recording is not enough. Designed for eave, soffit, and wall mounting across commercial perimeters, driveways, shopfronts, and high-risk residential entry points, this camera does not wait for an incident to be reviewed later. When SMD 4.0 detects a human or vehicle target, it immediately triggers red and blue strobe lights and a 110dB built-in speaker alarm, issuing a real-time deterrent before an intrusion develops. The motorised 2.7-13.5mm varifocal lens allows remote optical adjustment post-installation, removing the need for a return site visit. Starlight dual illumination delivers full-colour footage in complete darkness, and AcuPick AI search makes locating specific events in recorded footage fast and practical. IP67 weather resistance suits year-round outdoor use across Australian conditions.
Key Capabilities
8MP Ultra-HD Resolution
Capturing at 3840×2160 resolution and up to 30fps, this camera produces footage with sufficient detail to identify faces, read number plates, and support post-incident investigations across wide outdoor coverage areas.
Motorised Varifocal Lens
The 2.7-13.5mm motorised lens adjusts remotely through the NVR or compatible app, allowing precise field-of-view framing without physically re-accessing the camera. This is especially valuable on high or difficult-to-reach mounting positions on eaves and soffits.
TiOC Dual Illumination
Smart Illumination mode keeps IR active at rest and switches to warm white light on target detection, providing full-colour footage on demand. IR-only and continuous white-light modes are also configurable to match site conditions and light-pollution sensitivities.
Active Deterrence with Two-Way Audio
Red and blue strobe lights and a 110dB built-in speaker fire simultaneously on detection. The built-in microphone enables two-way audio through the app, letting a user speak directly to anyone on site in real time. Customisable voice messages can also be pre-configured for specific scenarios.
SMD 4.0 Smart Motion Detection
SMD 4.0 classifies humans and vehicles with high accuracy, filtering out animals, foliage, car headlights, and other non-target triggers. The false alarm rate is kept under 2%, keeping push notifications meaningful and reducing alert fatigue for operators and end users.
AcuPick AI Smart Search
AcuPick uses AI-tagged metadata from recorded events to filter footage by human or vehicle targets, retrieving relevant clips in seconds rather than requiring manual scrubbing through hours of continuous recording after an incident.
Best For
Commercial Perimeters and Car Parks: The varifocal lens frames entry and exit points precisely, vehicle SMD 4.0 detection triggers accurate alerts, and the strobe alarm provides visible deterrence visible across open outdoor areas.
Shopfronts and Retail Premises: Full-colour night footage and two-way audio allow after-hours monitoring with real-time verbal intervention, supporting deterrence without requiring on-site personnel.
Residential Driveways and High-Risk Entry Points: The camera’s active deterrence fires before an intruder reaches the property, and real-time push notifications with one-tap arming let homeowners respond immediately from their phone.
Warehouses and Industrial Yards: Large spaces with variable ambient lighting benefit from the smart dual illumination switching, and SMD 4.0 filters vehicle and forklift movement from genuine after-hours intrusion attempts.
Sites Requiring Post-Installation Lens Adjustment: Where the ideal field of view cannot be determined before installation is complete, the remote motorised zoom eliminates revisit costs and speeds up commissioning.
Why Choose the IPC-HDW3849H-ZAS-PV-ANZ-S2
A standard turret camera records events after they occur. The Dahua IPC-HDW3849H-ZAS-PV-ANZ-S2 is built to interrupt them while they are happening. The combination of red and blue strobe lights, a 110dB speaker, and real-time two-way audio in a single turret body removes the need for separate deterrence hardware, reducing wiring complexity and installation time on commercial jobs. The motorised 2.7-13.5mm varifocal lens delivers framing flexibility that fixed-lens alternatives cannot provide, and SMD 4.0 keeps the false alarm rate under 2%, making this camera genuinely practical to manage at scale. AcuPick AI search reduces post-incident investigation time from hours to minutes. Available through Security Wholesalers with full Australian warranty and regional support, the ANZ-S2 designation confirms this is a locally distributed unit, not a grey import.
Buyer Decision Tips
Buyer Tip: The camera ships in Smart Illumination Mode by default, meaning it stays in IR until a target is detected and only then switches to colour white light. If the installation site requires continuous full-colour night footage rather than colour-on-detection, switch the illumination mode to White Light Only during setup. For sites near residential boundaries, Smart Illumination Mode is generally the more appropriate choice to avoid unnecessary light pollution during quiet periods.
Buyer Tip: SMD 4.0 and AcuPick require a WizSense-compatible NVR to function. Pairing this camera with a basic NVR will still provide 8MP recording but will disable all AI-driven features, including smart motion classification and rapid event search. Confirm NVR compatibility before purchasing to retain the full value of this camera’s capability set.

Ideal Use Cases
Driveways and Gate Entries
The motorised varifocal lens frames entry points precisely regardless of distance, while vehicle SMD 4.0 detection and 8MP resolution support both deterrence on arrival and number-plate-quality evidence capture for review.
Shopfronts and After-Hours Retail
Full-colour night footage removes the ambiguity of IR-only footage during after-hours incidents, and two-way audio allows a monitoring operator to address and deter individuals loitering at a shopfront in real time.
Building Perimeters and Fence Lines
Perimeter protection mode combined with red and blue strobe deterrence positions the camera’s response at the boundary level, before an intruder reaches the building or asset being protected.
Warehouses and Loading Docks
SMD 4.0 separates after-hours human intrusions from routine vehicle movement such as trucks and forklifts during handover periods, keeping security alerts specific and reducing unnecessary alarm escalations during busy operational transitions.
Residential Side Passages and Back Yards
Side passages and rear access points are common entry routes that benefit from active response rather than passive recording. The strobe and speaker alarm can deter an intruder within seconds of detection, before any manual intervention is required.
Choosing the Right Model
Choose this model if: You need a single turret camera that delivers 8MP full-colour night vision, active deterrence with strobe and speaker, two-way audio, and remote motorised zoom in one unit, particularly for outdoor sites where intervention capability and post-incident evidence quality both matter.
Choose a different model if: Your site has a fixed close-range coverage requirement with no need for zoom adjustment, or active deterrence features are not required and budget is a priority. A fixed-lens WizSense turret will still provide SMD detection and full-colour night vision at a lower cost point where the motorised lens and deterrence hardware add unnecessary complexity.
FAQs
What does TiOC mean and what separates it from a standard outdoor turret camera? TiOC stands for Three-in-One Camera, combining 24/7 full-colour monitoring, active deterrence, and AI detection in a single housing. Unlike a standard turret that records passively, the IPC-HDW3849H-ZAS-PV-ANZ-S2 detects a human or vehicle target and immediately fires strobe lights and a 110dB speaker alarm while sending a real-time push notification, allowing intervention before an incident progresses.
Does the camera produce colour footage at night without any external lighting? Yes. The Starlight sensor combined with the built-in warm white illuminator delivers full-colour footage in complete darkness. In Smart Illumination Mode, the camera stays in IR until a target is detected, then switches to white light for colour footage. In White Light Mode, colour video is produced continuously throughout the night regardless of ambient lighting.
Can the varifocal lens be adjusted after the camera is mounted on the wall or eave? Yes. The 2.7-13.5mm motorised varifocal lens is adjusted remotely through the connected NVR interface or compatible Dahua software. There is no need to physically access the camera to change the field of view, which makes it practical for installations on high eaves, soffits, or tight corners where re-access is time-consuming or costly.
What NVR is required to unlock the AI features on this camera? This camera requires a Dahua WizSense-compatible NVR to enable SMD 4.0 human and vehicle classification, AcuPick smart search, and perimeter protection mode. Connecting it to a non-WizSense NVR will provide 8MP recording but will disable the AI-driven functions. Confirm NVR compatibility before purchasing to retain the full feature set.
How does SMD 4.0 reduce false alarms compared to standard motion detection? Standard motion detection triggers on any pixel change, including wind-blown foliage, shadows, insects, and car headlights. SMD 4.0 applies AI classification to confirm whether a detected object is a human or vehicle before issuing an alert. This keeps the false alarm rate under 2%, meaning notifications are genuinely actionable rather than a source of alert fatigue.
Is the two-way audio feature available out of the box or does it need additional equipment? Two-way audio is built in. The IPC-HDW3849H-ZAS-PV-ANZ-S2 includes both a built-in microphone and a built-in speaker, so no external audio hardware is needed. Real-time voice communication is accessible through the connected app when a detection event occurs, allowing a user to speak directly to anyone in the camera’s field of view.
How weatherproof is this camera for outdoor use in Australian conditions? The camera carries an IP67 rating, meaning it is fully sealed against dust ingress and protected against water immersion up to 1 metre. It is suitable for exposed outdoor mounting across Australian climates including rain, heat, and coastal humidity. The turret housing also reduces lens flare and water pooling compared to dome designs.
Where is this camera available and does the ANZ suffix matter for warranty? The Dahua IPC-HDW3849H-ZAS-PV-ANZ-S2 is part of the Security Wholesalers range, supplied as a locally distributed unit for the Australian and New Zealand market. The ANZ-S2 designation in the model code confirms it is not a grey import, and it is backed by Dahua’s regional warranty and technical support infrastructure rather than an international warranty that may not apply in Australia.
