Dahua DH-IPC-HDW3849H-AS-PV-ANZ-S2 8MP WizSense TiOC Turret 2.8mm SMD 4.0 Smart Dual Light AcuPick Active Deterrence Two-Way Audio

The Dahua DH-IPC-HDW3849H-AS-PV-ANZ-S2 is a full-featured 8MP WizSense TiOC turret camera that combines active deterrence, Smart Dual Light illumination, and SMD 4.0 AI detection in a compact IP67-rated housing. All TiOC functions — active deterrence, dual illumination, two-way audio and SMD 4.0 recording — work with current Dahua NVRs straight out of the box. Built for Australian homes, businesses and security installers who need a camera that responds to threats rather than just recording them. Ships from Australian warehouses with full local warranty support.

Smart Dual Light — Full-Colour When It Counts, Discreet IR Between Events

Unlike cameras that run white light all night, the DH-IPC-HDW3849H-AS-PV-ANZ-S2 uses Smart Dual Light to give you precise control over how the camera behaves after dark:

Both illuminators cover up to 30 metres. In Smart mode, neighbours and the surrounding environment experience no light intrusion between detection events — only at the precise moment the camera needs to identify what triggered it.

SMD 4.0 — AI Detection That Cuts Through the Noise

Dahua’s SMD 4.0 (Smart Motion Detection 4.0) classifies motion targets as human or vehicle before triggering any alert — eliminating false alarms from animals, foliage, passing headlights and weather. Perimeter protection covers intrusion and tripwire, both filtered by target type. For homeowners who’ve given up on motion-triggered cameras after too many 3am alerts from passing cats, or business owners managing sites where general motion is constant, SMD 4.0 is the difference between a security system you trust and one you ignore.

Active Deterrence — Strobe + Audio Alarm That Fires on AI Confirmation

The built-in strobe light and audio alarm activate on SMD 4.0-confirmed human or vehicle intrusion — not on general motion. A deterrence system that fires on every passing shadow becomes background noise within days. On this camera, deterrence is specific and deliberate. The active deterrence schedule is fully configurable — restrict to after-hours, disable the strobe while retaining AI recording and alerts, or run full active response at all times. For residential driveways, retail shopfronts, construction sites and industrial yards across Australia, this is proactive prevention rather than after-the-fact evidence.

Full Two-Way Audio — Dual Microphone + Speaker

A built-in dual microphone captures clear audio in outdoor environments with noise reduction applied for intelligible recordings. The integrated speaker enables real-time voice communication via the DMSS app from any smartphone or desktop — address visitors, warn intruders, or communicate with delivery personnel without being on-site. Audio and alarm interfaces (1 in, 1 out) also support external connections for more complex integrations.

AcuPick — AI Target Search for Post-Incident Review

The DH-IPC-HDW3849H-AS-PV-ANZ-S2 also supports AcuPick — Dahua’s AI-powered footage search that lets you find a specific person or vehicle across hours of recorded footage in seconds using appearance attributes. This is a valuable additional capability for commercial and multi-camera deployments where rapid identification matters after an incident. Note: AcuPick requires a Dahua NVR5 Series NVR for this search function specifically — all other TiOC features including SMD 4.0, active deterrence, dual illumination and two-way audio work with current Dahua NVRs.

PoE 802.3af — Single Cable Installation, Compatible with Current Dahua NVRs

The DH-IPC-HDW3849H-AS-PV-ANZ-S2 runs on standard IEEE 802.3af PoE, drawing power over a single Cat6 cable from any compatible Dahua NVR PoE port or standard PoE switch — no separate power supply required. ONVIF compliance is supported; note that ONVIF compliance does not guarantee full feature support on third-party NVR systems.

Where This Camera Earns Its Place Across Australia

🏠 Residential — driveways, entry points and rear access — Smart mode keeps the yard dark between events; active deterrence fires the moment a person is confirmed in-frame; two-way audio lets homeowners respond from their phone without opening a door

🏪 Retail shopfronts and small commercial — strobe and siren deter opportunistic break-ins after hours without requiring a monitoring station; SMD 4.0 keeps alerts meaningful so you actually check them

🏭 Warehouses and industrial sites — IP67 weatherproofing and SMD 4.0 filtering handle demanding outdoor environments where general motion triggers would overwhelm the alert system; alarm I/O supports integration with site access systems

🏢 Offices and commercial buildings — two-way audio enables security staff or reception to communicate directly with anyone in the camera’s field of view; pairs with Dahua NVR for multi-camera perimeter monitoring with SMD 4.0 event search

⚡ Electricians and security installers — standard 802.3af PoE means no infrastructure surprises; plug into any current Dahua NVR PoE port for immediate TiOC functionality; AcuPick available as an upgrade path for clients who later specify NVR5 Series
