Product SKU: DH-IPC-HFW3849T1-AS-PV-ANZ-BLK
Product Overview
Combining active deterrence with full-colour AI surveillance, the Dahua TiOC 2.0 IPC-HFW3849T1-AS-PV is an 8MP outdoor bullet camera built to intervene the moment a threat is detected rather than simply recording it. Mounted on a wall, eave, or soffit facing a driveway, gate, car park, or building perimeter, this black-finish ANZ model triggers red and blue strobe lights and a 110dB built-in speaker alarm automatically on detection. Smart Motion Detection 4.0 classifies humans and vehicles with onboard AI, keeping the false alarm rate under 2% so every alert carries weight. The smart dual illuminator system runs in infrared by default and switches to warm white light on motion, producing full-colour footage at night without constant light spill. With dual built-in microphones and a 1-channel speaker enabling two-way audio, IP67 weatherproofing, and support for both PoE and 12VDC power, this camera is engineered for demanding Australian outdoor environments where passive monitoring is not enough.



Key Capabilities
TiOC 2.0 Active Deterrence
Red and blue strobe lights combined with a 110dB speaker alarm activate automatically on detection, confronting intruders at the perimeter before an incident develops. The visible strobe is effective even through fog and heavy rain, giving this bullet camera a deterrence capability that passive recording cannot match.
8MP 4K Resolution
A 1/2.8″ CMOS sensor delivers 3840 x 2160 at up to 25/30fps, capturing enough detail for face and number plate identification across driveways, car parks, and entry zones. The wide 2.8mm fixed lens maximises scene coverage at close to medium range without sacrificing image sharpness.
Smart Dual Illuminators
In the default Smart Mode, IR runs continuously and switches to warm white light when a human or vehicle is detected, producing full-colour footage on triggered events without flooding the surrounding area with constant white light. IR-only and white-light-only modes are also configurable per installation.
SMD 4.0 AI Detection
Smart Motion Detection 4.0 uses onboard AI to distinguish humans and vehicles from animals, foliage, and passing headlights. The result is a false alarm rate under 2%, meaning operators and monitoring staff respond only to genuine intrusions rather than constant irrelevant triggers.
Two-Way Audio
Dual built-in microphones and a 1-channel speaker support real-time two-way communication through a compatible NVR or the Dahua mobile app. Operators can issue verbal warnings directly through the camera or speak with visitors at a gate without requiring separate intercom hardware.
Flexible Storage and Compression
H.265+, H.264+, Smart Codec, AI Codec, and ROI encoding reduce bandwidth and storage consumption significantly. A built-in Micro SD card slot supports up to 256GB for standalone local recording, and 1 alarm input and 1 alarm output allow integration with existing security panels.
Best For
- Residential Driveways and Entry Points: The 2.8mm wide-angle lens covers gates, front doors, and driveway approaches comprehensively, with active strobe and siren deterrence triggered automatically on human or vehicle detection.
- Small Business Perimeters: Retail yards, warehouses, and commercial premises benefit from SMD 4.0 human and vehicle classification delivering accurate after-hours alerts without excessive false alarm fatigue.
- Car Parks and Open Outdoor Areas: Full-colour night vision at 30m range and 8MP resolution allow reliable person and number plate identification across large open spaces in low-light conditions.
- Construction and Industrial Sites: IP67 weatherproofing and PoE or 12VDC power options simplify deployment in temporary or harsh outdoor environments where equipment theft and after-hours trespass are ongoing concerns.
- Remote or Unstaffed Locations: Real-time mobile push notifications, one-tap arming and disarming via alarm input, and two-way audio allow site managers to monitor and respond to events from any location without on-site staffing.
Why Choose the DH-IPC-HFW3849T1-AS-PV-ANZ-BLK
Most outdoor bullet cameras capture an event after it has already happened. The IPC-HFW3849T1-AS-PV changes that dynamic by triggering red and blue strobe lights and a 110dB speaker alarm the instant SMD 4.0 detects a human or vehicle, creating an active deterrence layer that a basic recording camera cannot replicate. The smart illuminator switching means the camera produces full-colour night footage on detection without maintaining constant white-light output across your property. At 8MP, identification detail across driveways, car parks, and perimeter zones is substantially sharper than 4MP or 5MP alternatives. The black ANZ finish is the locally supported variant with Australian firmware, making it the appropriate choice for Australian and New Zealand installations rather than international grey-market stock. Available through Security Wholesalers, this model also includes a built-in Micro SD slot for standalone recording and alarm I/O for integration with existing security infrastructure.
Buyer Decision Tips
Buyer Tip: The 2.8mm fixed lens delivers a wide field of view best suited to close-to-medium range coverage such as driveways, gateways, and building entrances. If your installation requires narrower framing to identify subjects at longer distances, a longer focal length is a better fit than this 2.8mm model. Measure your coverage distance before purchasing to confirm this lens suits the specific zone you are monitoring.
Buyer Tip: This camera supports both PoE and 12VDC power. PoE is the most practical option for new cable runs as it delivers data and power over a single Cat5e or Cat6 cable. Before deploying, confirm that your NVR or PoE switch provides 802.3af or 802.3at output on the relevant port. This avoids the need for a separate power supply at the camera mounting point.

Ideal Use Cases
Driveway and Gate Monitoring
The 2.8mm wide-angle lens covers driveway approaches and gate entry points comprehensively. When a human or vehicle is detected, the strobe and siren activate immediately, confronting intruders at the perimeter rather than after they have already entered the property.
Retail and Commercial Yards
SMD 4.0 human and vehicle classification keeps false alarm rates under 2%, so security staff at retail stores and commercial yards receive actionable alerts rather than constant noise. Two-way audio allows direct communication with individuals on site without additional hardware.
Car Parks and Open Outdoor Areas
8MP resolution and full-colour night vision at 30m range support number plate and person identification across large open areas after dark. The audible alarm deters vandalism and vehicle theft before damage or loss occurs.
Construction and Industrial Sites
IP67 weatherproofing and support for both PoE and 12VDC power make this camera straightforward to deploy in temporary or harsh outdoor environments. The active deterrence system responds to after-hours intrusions autonomously, without requiring on-site personnel.
Remote and Unstaffed Locations
Real-time mobile push notifications and one-tap arming/disarming via alarm input allow site managers to monitor and respond to detection events remotely. The camera operates autonomously, activating deterrence and recording events without requiring a human operator to initiate a response.
Perimeter Security Integration
With 1 alarm input and 1 alarm output, the camera connects directly to existing alarm panels and access control systems. This allows TiOC 2.0 deterrence events to trigger third-party systems or be triggered by external inputs as part of a broader layered perimeter security setup.
Choosing the Right Model
- Choose this model if: You need 8MP full-colour AI surveillance with active deterrence including strobe lights and a speaker alarm in a directional outdoor bullet form factor. The black ANZ finish suits modern installations and the built-in two-way audio, SD card slot, and alarm I/O make it a complete standalone unit for driveways, yards, and perimeter zones.
- Choose a different model if: Your coverage zone requires a narrower field of view to identify subjects at longer distances, where a longer focal length or motorised varifocal lens would be more appropriate. If you need to actively track movement across a large area, a PTZ camera is a better fit than this fixed-lens bullet.
FAQs
- What does TiOC 2.0 mean and what makes it different from a standard IP bullet camera?
TiOC stands for Three-in-One Camera, combining full-colour 24/7 video, AI-powered motion detection, and active deterrence in a single unit. Version 2.0 upgrades the original with SMD 4.0 detection, smarter illuminator switching, and enhanced audio output. A standard IP bullet camera records events after they occur; TiOC 2.0 responds to them in real time by triggering a strobe and siren alarm the moment a human or vehicle is detected. - How does the smart dual illuminator switch between IR and white light?
In the default Smart Mode, the camera runs continuously in infrared and automatically switches to warm white light when SMD 4.0 detects a human or vehicle. This produces full-colour footage on triggered events without maintaining constant white-light output across the scene. Both IR-only and white-light-only modes are available if your installation has specific lighting requirements. - What is the effective coverage range for this camera at night?
Both the IR illuminator and the warm white light illuminator have a rated range of 30m. At that distance, the 2.8mm wide-angle lens provides broad scene coverage suited to driveways, gates, and building entry points. If your target zone extends significantly beyond 30m, a camera with a longer focal length and greater illumination range would be more appropriate for your layout. - Does this camera support two-way audio out of the box?
Yes. The IPC-HFW3849T1-AS-PV includes dual built-in microphones and a 1-channel speaker, enabling real-time two-way audio through a compatible Dahua NVR or the Dahua mobile app. No additional microphone or speaker hardware is required. Operators can issue verbal warnings or speak with people at the camera location directly from their monitoring interface. - Can this camera record locally without an NVR?
Yes. The camera includes a Micro SD card slot supporting up to 256GB, which allows standalone local recording independent of an NVR. For full access to AI event management, remote monitoring across multiple cameras, and push notifications, pairing with a compatible Dahua NVR is recommended. - What does SMD 4.0 do and how does it reduce false alarms?
Smart Motion Detection 4.0 uses onboard AI to classify detected objects as humans or vehicles, filtering out triggers caused by animals, blowing leaves, insects, and passing vehicle headlights. This keeps the false alarm rate under 2%. For sites receiving large numbers of irrelevant motion alerts from standard cameras, SMD 4.0 significantly reduces alert fatigue and ensures responses are directed at genuine events. - Is the black finish ANZ model different from the standard international version?
Yes. The ANZ variant is the locally supported version configured with Australian and New Zealand firmware. This ensures compatibility with local Dahua support channels and system requirements. It is the correct version to specify for Australian and New Zealand installations rather than international or grey-market stock that may have different firmware or lack local support. This model is available through Security Wholesalers as part of their professional IP surveillance range. - What power options are supported and how do I confirm PoE compatibility?
The camera accepts both 12VDC and Power over Ethernet. PoE is the most practical option for most installations as it runs data and power over a single Ethernet cable, removing the need for a separate power run to the mounting point. Before deploying, confirm that your NVR or PoE switch provides 802.3af or 802.3at output on the port you intend to use. Not all switches and NVRs supply full PoE power on every port simultaneously, so check the device specifications against your camera count and cable run lengths.
