Dahua DH-IPC-HDW3649H-AS-PV-ANZ-S2 — 6 MP TiOC 3 AcuPick Active Deterrence Full-Colour Starlight Turret WizSense Network Camera (3649 Series)

Dahua's DH-IPC-HDW3649H-AS-PV-ANZ-S2 is the fixed-lens TiOC 3 turret in the 3649 series with AcuPick built in — effectively three devices sharing one housing: a round-the-clock surveillance camera, a live alarm unit and an audio-visual intruder deterrent. A 1/1.8" CMOS Starlight sensor delivers 6 MP (3288 × 1850) at 25/30 fps with Smart H.265+ compression behind a fixed 2.8 mm F1.6 lens (a 3.6 mm option is also offered). Smart Dual Illumination combines a 30 m IR illuminator with a 30 m warm-light array so the camera can see in full colour after dark. The moment WizSense confirms a person or vehicle inside an IVS zone, the unit fires red and blue strobe lighting together with an audible alarm from the onboard siren and speaker — the same light-and-sound pattern used on Australian police-vehicle warning bars. Two-way audio through the integrated mic and speaker lets an operator talk straight to whoever is on camera via the DMSS app. WDR is rated at 140 dB, the enclosure carries an IP67 seal, and SMD 4.0 screens out animals and moving foliage on the camera itself so only people and vehicles generate alerts. With edge AcuPick, a matching Dahua AcuPick NVR can search recordings by attributes such as colour, clothing, vehicle type and travel direction. It suits Australian homes, NDIS properties, retail shopfronts, depot perimeters, small businesses and rural blocks where one visible camera needs to record AND actively scare intruders off. It runs on 12 VDC or PoE (802.3af) with a peak draw of roughly 10 W, and is covered by a 3-year Australian warranty. Part of the 3649 series — a black-bodied version is sold as the HDW3649H-AS-PV-ANZ-BLK.

Why Choose the Dahua HDW3649H-AS-PV-ANZ-S2 TiOC Turret

When the job spec reads "prevent the break-in, not just film it", this is the turret Australian installers keep coming back to. Six things set it apart from ordinary 6 MP turrets in the same price bracket.

Red & Blue Strobe + Built-in Siren

Whenever WizSense confirms a person or vehicle inside an IVS zone, the TiOC deterrence stack kicks in automatically: red/blue strobe lighting and an audible siren from the onboard speaker. The pattern mirrors police-vehicle warning lights — a cue most intruders instinctively respond to by leaving.

Two-Way Audio Talk-Down

Full live two-way conversation is possible through the built-in microphone and speaker using the free DMSS mobile app. Address a courier, a visitor or an unwanted guest from wherever you have an internet connection — effectively a remote PA speaker on your wall.

True 6 MP Full-Colour Night Vision

Thanks to the 1/1.8" Starlight CMOS, the camera keeps recording 3288 × 1850 colour footage even in very dim conditions. Add the 30 m warm-light array and you get usable colour evidence at night, where basic IR-only units deliver nothing but monochrome silhouettes.

SMD 4.0 — Only Alerts on Real Targets

Smart Motion Detection 4.0 discards swaying branches, possums along the fence line, shadows and small animals right at the edge — alerts fire for people and vehicles only. The payoff is far fewer false alarms, so a DMSS notification actually means something.

AcuPick-Ready Edge AI

Record to a Dahua AcuPick NVR and you can query hours of footage by description — "red top, white sedan, walking east" — and get matching clips back in seconds instead of manually scrubbing a timeline. Pair the right Dahua NVR with this 3649-series camera and it becomes a genuine forensic search tool.

Discreet Turret, IP67 Sealed

The compact eyeball housing sits neatly on eaves, soffits, awnings and covered ceilings, giving a clean architectural look rather than an obtrusive bullet profile. It is IP67-sealed against driving rain and carries the RCM mark for Australia.

Important Install Note

Because the HDW3649H-AS-PV-ANZ-S2 is a fixed-focal camera, take care framing the shot during installation — there is no remote re-framing afterwards. The eyeball gimbal allows ±75° pan, ±75° tilt and 0–360° rotation at the mount, so you have plenty of adjustment at setup. Audio recording note: for NDIS, retail and public-space deployments, confirm local audio-recording legislation before switching on sound recording. On exposed coastal or humid outdoor installs, add the DH-PFA137 in-ceiling junction box to keep condensation away from the RJ-45 termination. The camera comes in standard white (this listing) or black (HDW3649H-AS-PV-ANZ-BLK).

AI & Smart Detection Capabilities

TiOC Active Deterrence (Red & Blue + Siren)

Deterrence can be linked to any IVS event — tripwire, intrusion, or motion filtered by target type. On trigger, the camera runs red/blue strobe lighting and a configurable audible alarm through the built-in speaker, and you can upload custom sound files for site-specific warnings.

WizSense Human & Vehicle Classification

Deep-learning models running on the camera itself sort every motion event into human, vehicle, animal or "other" before an alert is ever sent. That strips away the clutter that plagues generic motion-detection cameras and cuts alarm fatigue on busy properties.

AcuPick Attribute Search

Attribute-level deep-learning matching across people and vehicles. Locate a subject across hours of recordings by colour, upper/lower clothing, vehicle type and direction — available when recording to a compatible Dahua AcuPick NVR.

SMD 4.0 Smart Motion

Motion notifications come only from humans and vehicles; wind, vegetation, small animals and shadows are rejected on-device. That dramatically reduces nuisance alarms on residential, NDIS and rural properties.

Perimeter Protection (IVS)

Set up tripwire lines and intrusion zones with human/vehicle classification built in. Draw a line over a driveway or a polygon around a yard, and an alert (plus the deterrence response) fires only when the correct target type crosses it.

Two-Way Audio via DMSS

The integrated mic and speaker deliver full-duplex two-way audio via the free DMSS app — immediate voice contact from anywhere online. Handy for courier instructions, greeting visitors or warning off intruders.

How It Compares — HDW3649H-AS-PV-ANZ-S2 vs HDW3649H-ZAS-PV-ANZ (Motorised Zoom)

Its nearest relative is the Dahua DH-IPC-HDW3649H-ZAS-PV-ANZ — the motorised vari-focal edition of the same camera. Sensor, TiOC active deterrence and Starlight low-light performance are all identical; the choice comes down to a fixed lens (cheaper, simpler to fit) versus motorised optics (adjustable framing from the app and greater reach).

Frequently Asked Questions

What does "TiOC 3" mean?

TiOC is short for "Three-in-One Camera" — Dahua's label for units that merge 24/7 video surveillance, real-time AI alarms and active deterrence (strobe, siren and two-way audio) into a single housing. TiOC 3 is the current generation, bringing native AcuPick attribute search, sharper SMD 4.0 classification and refined Smart Dual Illumination to the same Three-in-One platform.

Does the camera include AcuPick?

Yes — AcuPick attribute search ships inside the camera's WizSense firmware. To run attribute searches over recorded footage, however, you need to record to a compatible Dahua AcuPick NVR on V5 firmware.

Is the active deterrence too loud for residential use?

No — alarm volume adjusts from 0–100% and the number of plays per trigger can be set anywhere from 1 to 10, with support for uploading custom sound files. In practice, most home installs sit at 30–50% volume: enough to confront an intruder without upsetting the neighbours.

Can I use this camera for two-way intercom?

Yes — full-duplex two-way audio runs over the built-in microphone and speaker through Dahua's free DMSS mobile app, which is handy for courier instructions, greeting visitors and challenging intruders. NDIS, retail and public-space operators should verify local audio-recording legislation before enabling sound recording.

Can I run this camera on standard PoE?

Yes — it complies with 802.3af and draws a maximum of about 10 W. Any decent 802.3af switch with spare power budget will drive it without issue; the pricier 802.3at PoE+ standard isn't required.

What's the difference between the fixed and motorised versions?

This camera, the fixed HDW3649H-AS-PV-ANZ-S2, carries a 2.8 mm or 3.6 mm lens set at install time — cheaper and simpler. Its motorised sibling, the HDW3649H-ZAS-PV-ANZ, has a 2.7 – 13.5 mm motorised vari-focal lens that can be re-framed remotely through the DMSS app, along with longer 50 m IR / 50 m warm-light reach.

Is the black version available?

Yes — an identical camera in black sells under the DH-IPC-HDW3649H-AS-PV-ANZ-BLK SKU. The black finish disappears into darker architecture — colourbond eaves and modern minimalist soffits — where a white body would be conspicuous.

Does it work with third-party NVRs?

Yes — with ONVIF Profile S, G and T support it records to any ONVIF-compatible third-party NVR. Bear in mind that AcuPick attribute search and SMD 4.0 alarm push are end-to-end features requiring a genuine Dahua AI NVR, and IVS-driven active-deterrence triggers only operate on Dahua firmware.

Can I view the camera live on my phone?

Yes — it pairs with Dahua's free DMSS app for iOS and Android. Scan the QR code on the housing to add the device, sign in, and you have live view, two-way audio, motion alerts and playback of recordings from anywhere online — with no subscription fee.
