Product SKU: DH-IPC-HFW3849T1-AS-PV-ANZ-BLK
Product Overview
The Dahua TiOC 2.0 IPC-HFW3849T1-AS-PV is an 8MP AI-powered active deterrence bullet camera engineered for serious outdoor surveillance. Combining full-colour 24/7 monitoring, SMD 4.0 smart motion detection, and an integrated red/blue strobe alarm with built-in speaker, this camera doesn’t just record threats — it actively discourages them. The 2.8mm fixed lens delivers a wide field of view suited to driveways, car parks, building entrances, and perimeter zones. Smart dual illuminators switch automatically between infrared and warm white light depending on the scene, ensuring clear colour footage at night without unnecessary light pollution. With two-way audio via dual built-in microphones and a 1-channel speaker, operators can communicate directly through the camera. IP67 weatherproofing and PoE or 12VDC power supply make installation straightforward in virtually any outdoor environment.



Key Capabilities
8MP 4K Resolution
A 1/2.8″ CMOS sensor delivers up to 3840 × 2160 at 25/30fps, capturing fine detail for reliable identification of faces, number plates, and activity even at the edges of the frame.
TiOC Active Deterrence 2.0
Red and blue strobe lights combined with a 110dB speaker alarm trigger automatically on detection, warning intruders before an incident escalates. Visible even in fog and heavy rain, this is a genuine first line of defence.
Smart Dual Illuminators
The camera intelligently switches between 30m IR and 30m warm white light based on motion events. In default Smart Mode, IR runs continuously and switches to white light when a target is detected, producing full-colour footage without constant light pollution.
SMD 4.0 AI Detection
Smart Motion Detection 4.0 uses AI to accurately distinguish humans and vehicles from animals, leaves, and headlights, keeping the false alarm rate under 2% and ensuring security staff respond only to genuine events.
Two-Way Audio
Dual built-in microphones and a 1-channel speaker enable real-time voice communication directly through the camera. Operators can issue verbal warnings or communicate with visitors without additional intercom hardware.
Flexible Compression & Storage
H.265+, H.264+, Smart Codec, AI Codec, and ROI encoding reduce bandwidth and storage demands significantly. The camera supports up to 256GB Micro SD card local storage and includes 1 alarm input and 1 alarm output for system integration.

Why Choose the DH-IPC-HFW3849T1-AS-PV-ANZ-BLK
Standard IP cameras record events after the fact — the Dahua TiOC 2.0 stops them from happening in the first place. The combination of SMD 4.0 AI detection, red/blue strobe lights, and a 110dB speaker creates an active deterrence system that reacts the moment a human or vehicle is detected, not minutes later when footage is reviewed. Compared to a basic 8MP bullet camera, you get three layers of protection: full-colour 24/7 video, AI-accurate motion alerts with under 2% false alarm rate, and an on-camera siren that works even in fog and heavy rain. The smart illuminator switching means you’re not flooding your neighbourhood with constant white light — the camera only activates it when needed. Available through Security Wholesalers, the black finish ANZ model is purpose-built for Australian and New Zealand conditions with local firmware support and IP67 weatherproofing as standard.
Buyer Decision Tips
Buyer Tip: The 2.8mm fixed lens provides a wide field of view best suited to close-to-medium range coverage such as doorways, gates, and driveways. If your installation requires a narrower field of view to cover longer distances, consider whether a different focal length better suits your layout before purchasing.
Buyer Tip: This camera supports both 12VDC and PoE power. If running a single cable is important to your installation, confirm your NVR or switch provides 802.3af/at PoE on the relevant port before deploying — this eliminates the need for a separate power run to the camera location.

- Choose a different model if: Your installation requires a varifocal lens for adjustable coverage distances, or you need a PTZ camera to track movement across a large area — the 2.8mm fixed lens on this model is optimised for wide, close-to-medium range coverage only.
FAQs
- What does TiOC 2.0 mean and how is it different from a standard IP camera?
TiOC stands for Three-in-One Camera, integrating full-colour 24/7 monitoring, active deterrence (strobe and siren), and AI detection into a single device. Version 2.0 improves on the original with SMD 4.0, smarter illuminator switching, and enhanced audio output. A standard IP camera records events; TiOC 2.0 actively intervenes to deter threats before they escalate. - What is SMD 4.0 and why does it matter?
Smart Motion Detection 4.0 uses onboard AI to classify detected objects as humans or vehicles, filtering out false triggers caused by animals, blowing leaves, or car headlights. This keeps the false alarm rate under 2%, meaning security teams respond only to genuine events rather than wasting time on irrelevant alerts. - How does the smart dual illuminator work at night?
In the default Smart Illumination Mode, the camera runs in IR mode and automatically switches to warm white light when a human or vehicle is detected. This produces full-colour footage on motion events while minimising light pollution the rest of the time. You can also set it to IR-only or white-light-only mode depending on your installation requirements. - Can I use this camera without an NVR for local storage?
Yes. The camera includes a Micro SD card slot supporting up to 256GB, allowing standalone local recording without an NVR. For full AI features, remote access, and multi-camera management, pairing with a compatible Dahua NVR is recommended. - Does this camera support two-way audio?
Yes. The camera includes dual built-in microphones and a 1-channel speaker, supporting real-time two-way audio through a compatible NVR or the Dahua mobile app. This allows operators to communicate directly through the camera — issuing verbal warnings or assisting visitors — without separate intercom hardware. - Is this camera compatible with third-party NVRs via ONVIF?
The DH-IPC-HFW3849T1-AS-PV is a Dahua product designed for use within the Dahua ecosystem. While many Dahua cameras support ONVIF, full AI and TiOC deterrence features including SMD 4.0 and active alarm triggers are only guaranteed when used with a compatible Dahua NVR. Check compatibility with your specific third-party recorder before purchasing. - Where can I purchase the DH-IPC-HFW3849T1-AS-PV-ANZ-BLK in Australia?
This camera is stocked and sold by Security Wholesalers, an Australian supplier specialising in professional-grade CCTV and IP surveillance equipment. The ANZ variant is the locally supported version with Australian firmware, making it the correct choice for Australian and New Zealand installations rather than grey-market imports. - What power options does this camera support?
The camera supports both 12VDC and Power over Ethernet (PoE). PoE is the most convenient option for new installations as it delivers both data and power over a single Ethernet cable, eliminating the need for a separate power run. Confirm your switch or NVR provides 802.3af/at PoE before deploying.
