Combining active deterrence with 8MP full-colour night imaging, the Dahua DH-IPC-HFW3849T1-ZAS-PV-ANZ-S2 is a TiOC 2.0 WizSense bullet camera built for outdoor perimeters where passive recording alone is not enough. Featuring Smart Dual Illumination with IR coverage up to 50m and warm white light up to 40m, it delivers full-colour footage during detected events without permanently flooding the scene. The motorised vari-focal lens allows field-of-view adjustment after installation, removing the need to physically reposition the housing during commissioning. SMD 4.0 AI classifies humans and vehicles with high accuracy, ensuring the red and blue strobe lights and 110dB speaker trigger on genuine threats rather than passing animals or windblown foliage. Built-in dual microphones and a 1-channel speaker enable two-way audio communication through compatible Dahua apps. Rated IP67, this camera suits driveways, commercial entrances, warehouse perimeters, and construction sites across Australian conditions.
Key Capabilities
8MP Ultra HD Imaging
A 1/2.8″ CMOS sensor captures 3840 x 2160 footage at up to 30fps, providing the resolution needed to identify faces, number plates, and scene detail that lower-resolution cameras routinely miss at the same viewing distance.
Smart Dual Illumination
IR LEDs cover up to 50m for continuous low-profile monitoring, while warm white LEDs cover up to 40m and activate automatically on human or vehicle detection. This keeps the scene dark during normal operation but delivers full-colour footage when it matters.
Active Deterrence: Strobe and Audio
Red and blue strobe lights remain visible in poor weather conditions and operate alongside a built-in speaker rated up to 110dB, issuing an immediate audio-visual response the moment a classified threat enters a defined detection zone.
SMD 4.0 Human and Vehicle Detection
Smart Motion Detection 4.0 precisely classifies humans and vehicles while filtering out animals, headlights, and foliage movement. This keeps false alarm rates low and ensures active deterrence responses are directed at genuine intrusion events.
Motorised Vari-focal Lens
Remote focal length adjustment via the NVR interface or web browser means installers can dial in the exact field of view from the ground after mounting, avoiding the need to repeatedly climb and reposition the camera bracket during commissioning.
Two-Way Audio
Dual built-in microphones and a 1-channel speaker allow operators to speak with and hear individuals on-site in real time through the Dahua DMSS app or compatible NVR, removing the need for a separate intercom device at monitored entry points.
Best For
Outdoor Perimeter Monitoring: The bullet housing, 50m IR range, and IP67 rating make this camera suited to fence lines, building exteriors, and long driveway approaches where directional, long-distance coverage is required.
Sites Requiring Active Intervention: Red and blue strobe lights combined with a 110dB speaker provide an automated deterrent response that challenges intruders before physical access or damage occurs.
Locations with Variable Lighting: Smart Dual Illumination adapts between IR-only and warm white light modes automatically based on detection events, making it suitable for sites that shift between complete darkness and ambient lighting across the night.
Remote or Unmanned Facilities: Mobile push notifications, one-click arming via alarm input, and two-way audio allow off-site operators to monitor and respond to incidents without deploying personnel to site.
Installations Requiring Precise Framing: The motorised vari-focal lens gives installers the flexibility to adjust coverage remotely after mounting, which is valuable on commercial and industrial sites where camera positions are determined before final cable routes are confirmed.
Why Choose the DH-IPC-HFW3849T1-ZAS-PV-ANZ-S2
A standard 8MP bullet camera records what happens. The DH-IPC-HFW3849T1-ZAS-PV-ANZ-S2 acts on it. The TiOC 2.0 architecture connects SMD 4.0 detection directly to the strobe and speaker output, so the deterrence response fires automatically on a classified human or vehicle event without manual operator input. The motorised vari-focal lens removes one of the most time-consuming parts of bullet camera commissioning, namely repositioning the housing to correct a miscalculated field of view. Smart H.265+ compression reduces storage overhead without sacrificing the detail that 8MP resolution provides. The dual illumination system means full-colour footage is available at night during active events, while IR-only mode avoids unnecessary light pollution at all other times. Micro SD support up to 256GB adds local storage redundancy for standalone or hybrid deployments. Available at Security Wholesalers as an ANZ market variant, this camera is built to integrate directly with Dahua NVR and DMSS platforms used across Australian residential and commercial installations.
Buyer Decision Tips
Buyer Tip: If the installation site is close to neighbouring properties or public roads, configure the camera in IR Mode so the warm white LEDs only activate on detection events rather than continuously. This reduces light spill into adjacent areas and is adjustable through the camera web interface or Dahua NVR menu after mounting.
Buyer Tip: Confirm your NVR supports 8MP resolution and Dahua AI features including SMD 4.0 before purchasing. Some older Dahua NVR models cap channel resolution at 4MP or 6MP, which means the camera will still function but will not record at full 8MP resolution or trigger AI-linked deterrence responses through the NVR interface.

Ideal Use Cases
Residential Driveways and Entry Gates
Full-colour night imaging activated on detection, combined with red and blue strobe lights and audio warning, gives homeowners a camera that responds visibly to intrusions at driveways, garages, and side gates rather than simply recording them.
Commercial Retail Exteriors
SMD 4.0 filters vehicle and foot traffic during trading hours and triggers accurate after-hours alerts when a person approaches a storefront, keeping loss prevention teams focused without nuisance notifications from passing traffic.
Industrial Warehouse Perimeters
IP67 weatherproofing and a 50m IR range make this bullet camera suited to wide industrial yards where exposed mounting and long-distance detection coverage across loading areas, fencing, and external storage are required.
Construction Sites
After-hours theft and vandalism at construction sites are a common concern. The visible bullet housing, strobe deterrence, and Micro SD local storage provide monitoring capability even on sites where network infrastructure is temporary or limited.
Car Parks and Vehicle Entry Points
Vehicle classification and tripwire detection identify unauthorised after-hours vehicle access, with the strobe and audio deterrence immediately challenging drivers entering restricted areas without requiring operator intervention.
Remote and Unmanned Facilities
Mobile push notifications and one-click arming via alarm input allow facilities managers to monitor and respond to after-hours events at unmanned sites without deploying physical guards, using two-way audio to challenge individuals remotely through the DMSS app.
Choosing the Right Model
Choose this model if: Your site needs a high-resolution outdoor bullet camera that actively deters intruders with strobe and audio, provides full-colour night vision on detection, supports two-way communication, and offers motorised vari-focal lens flexibility for post-installation framing adjustments.
Choose a different model if: Your application requires only passive recording with no active deterrence, a fixed-lens camera is sufficient for the coverage area, or your budget does not justify the motorised lens and dual illumination system this model includes.
FAQs
What does Smart Dual Illumination mean on this camera? Smart Dual Illumination means the DH-IPC-HFW3849T1-ZAS-PV-ANZ-S2 carries both IR LEDs and warm white LEDs. In its default Smart Illumination mode, the camera operates in IR-only mode during routine monitoring and automatically switches on the warm white light when SMD 4.0 classifies a human or vehicle in the scene, delivering full-colour footage during active events without permanently lighting the area.
How far can this camera see at night using IR? The IR illuminators provide a maximum range of 50m, while the warm white LEDs cover up to 40m. Effective range in practice depends on the focal length set on the motorised vari-focal lens and the reflectivity of objects in the scene. Longer focal lengths narrow the field of view but concentrate illumination further down the approach.
Does the active deterrence activate automatically or does an operator have to trigger it? SMD 4.0 can trigger the red and blue strobe lights and 110dB speaker automatically when a human or vehicle is detected within a configured zone, with no operator input required. It can also be activated manually through the Dahua DMSS app or a connected NVR. One-click arming via the alarm input supports scheduled arming and disarming without accessing the camera interface directly.
Is this camera compatible with existing Dahua NVRs? The DH-IPC-HFW3849T1-ZAS-PV-ANZ-S2 connects to Dahua NVRs using Dahua proprietary protocol and ONVIF. Before purchasing, confirm your NVR supports 8MP channel resolution and Dahua AI features including SMD 4.0 and active deterrence trigger outputs. Older Dahua NVR firmware may limit channel resolution or disable AI-linked functions.
Can this camera record locally without an NVR? Yes. The camera includes a Micro SD card slot supporting cards up to 256GB, enabling continuous or event-triggered local recording independently of a networked NVR. This suits standalone deployments, temporary installations, or as a backup recording layer when the primary NVR connection is interrupted.
Does this camera support PoE? Yes. The camera accepts both 12VDC and PoE power supply, meaning a single Cat5e or Cat6 cable can carry data and power from a compatible PoE switch or a Dahua NVR with built-in PoE ports. This simplifies cabling on installations where running a separate power feed to the camera position is impractical.
What is the difference between SMD 3.0 and SMD 4.0 on this model? SMD 4.0 is an updated iteration of Dahua’s AI-based motion classification engine. It offers improved accuracy in distinguishing humans and vehicles from other movement sources, including animals, headlights, and environmental movement. The result is fewer false alarm triggers in complex outdoor environments compared to earlier SMD generations, which is particularly relevant for sites where the active deterrence response needs to be reserved for genuine intrusion events.
Where can I purchase this camera and access support documentation in Australia? The DH-IPC-HFW3849T1-ZAS-PV-ANZ-S2 is available through Security Wholesalers, with the ANZ suffix confirming this is the Australian and New Zealand market variant. A datasheet and quick start guide are linked in the Additional Information section below.
