§ 01Overview
What this product is
Lens: motorised 2.7–13.5mm vari-focal.
The DH-IPC-HFW3849T1-ZAS-PV-ANZ-S2 puts the TiOC 3.0 deterrence package behind a motorised zoom in the body built for boundaries. Frame the shot from the app after mounting — 108° wide for a yard, down to a tight 34° on a gate or driveway throat — with faces identifiable to about 9 metres wide and 25.7 metres at full zoom. Infrared reaches 50 metres, the warm light 40.
The response set is current-generation: red and blue lights, siren and voice warnings through the speaker, warm-light full-colour event capture, two-way talk through dual mics, one-tap disarming in DMSS. The 8MP F1.0 sensor rates 0.004 lux in colour, SMD 4.0 with AI SSA filters the alerts, AcuPick works on compatible recorders, and MicroSD backup reaches 512GB.
The same honest notes as every vari-focal: this is set-and-leave framing, not a live-steered PTZ, and zoomed in means the wide view is gone until you change it. The motorised housing is rated -30°C to +60°C rather than -40°C — irrelevant anywhere in Australia. PoE-powered (10.3W max, all firing), IP67.

§ 04Why choose this
Built for the way you actually use it
Frame from the app, not the ladder
Mount it once, then tighten or widen the view from DMSS as the need changes — re-framing beats re-mounting every time.
Confront at the gate, not the door
Tripwires drawn at zoom distance fire the lights and voice warning while an intruder is still 20 metres from the building.
Zoomed in is zoomed in
Honest trade-off: one framed view at a time — at full zoom the 108° wide angle is gone. For wide coverage near the house, the fixed S2 bullet is simpler and cheaper.
§ 05Where it fits
Right at home in these scenarios
Front gates and long driveways
Zoom onto the entry 20-odd metres out; the tripwire fires lights and a voice warning at the boundary, recorded in full colour under the warm light.
Acreage fence lines
The bullet body aims down the run, 50m infrared covers it, and SMD 4.0 keeps stock and wildlife out of the alerts.
Commercial yard gates
Watch the actual entry point from the building wall — no cabling to a detached gatepost, with audio evidence from the dual mics where state rules allow.
Sites that change
Leased yards and evolving layouts: when the thing worth watching moves, the framing follows from the app.
§ 06Setup
Installation & setup
What's in the Box
1. Dahua DH-IPC-HFW3849T1-ZAS-PV-ANZ-S2 Camera × 1 2. Power Connector × 1 3. Quick Start Guide × 1
Installation Requirements
1. Power: any 802.3af PoE NVR port or switch (5.8W typical, 10.3W max with the lights and speaker running). A separate 12V DC adapter is only needed without PoE. 2. Network: a wired Ethernet run back to your NVR or switch — PoE carries power and video together on the same line. 3. Mounting: solid wall or pole with a clear sight line to the area you'll zoom onto. The optional PFA130-E junction box keeps the connection weatherproof.
App Setup
1. Download the DMSS app, create an account and scan the device QR code. 2. Set the zoom and focus from the app first — frame the gate or fence line before drawing any zones. 3. Then draw tripwire and intrusion zones on the framed view, and pick the warning voice and light schedule through the camera's web interface.
§ 07Questions
Frequently asked
Q.01
Is this a PTZ camera?
No — it's a motorised vari-focal: zoom and focus adjust from the app, then the view stays put. A PTZ pans and tilts on command all day; this camera is for framing one view precisely, not patrolling.
Q.02
How far can it identify someone?
About 9 metres at the wide end and 25.7 metres at full 13.5mm zoom. Infrared reaches 50 metres and the warm light 40 — when a person or vehicle is detected, the warm light fires and the event records in full colour.
Q.03
How do the deterrence features actually work?
When someone crosses a tripwire or enters an intrusion zone you've drawn, the camera reacts on the spot: the red and blue lights flash, the built-in speaker plays a siren or voice warning, and the warm light switches on so the whole event records in full colour. It ships with multiple warning voices and supports importing your own recordings.
Q.04
Can I turn the lights and siren off when I don't want them?
Yes — one-tap disarming in the DMSS app pauses all event linkage while you're expecting visitors, the web interface schedules deterrence by time of day or sets light-only with no sound, and there's a wired arm/disarm option through the alarm input for integrators.
Q.05
Will the siren and strobes annoy my neighbours?
They can if zones are drawn carelessly — this is a camera that reacts out loud. Draw tripwires and intrusion zones tight to your own property so footpath traffic never triggers them, schedule sound off overnight, or run light-only mode. If the camera would face a shared driveway or a tight terrace street, the quieter 3866 WizSense turret records the same AI events without the theatrics.
Q.06
Do the lights and siren work at zoom distances?
Yes — detection zones are drawn on whatever view you've framed, and the lights and voice warning fire when they're crossed. Bear in mind the speaker's audibility at 25 metres is a real-world limit: at gate distances the strobes do most of the deterring.
Q.07
Should I pick a bullet or a turret?
The bullet body is the visible one — from the street it reads as 'this property is covered', which is itself a layer of deterrence, and the long body aims naturally down fence lines and driveways. A turret like the HDW3849 S2 tucks under eaves more discreetly and suits ceilings. Same AI and deterrence either way — pick by mounting position and how visible you want the hardware.
Q.08
What is AcuPick and what do I need to use it?
AcuPick is Dahua's newest search: pick a person or vehicle in playback and the recorder matches them across every camera and timeline in seconds. It needs an AcuPick-capable Dahua recorder — on the AI NVRs in our kits you get SMD 4.0 classification and Quick Pick search, which still pulls every human or vehicle event from a day of footage in one pass.
Q.09
Which NVR do I need for this camera?
Any current Dahua PoE NVR records it. SMD classification, Quick Pick search and full event linkage want an AI model such as the DHI-NVR4104HS-P-AI/ANZ or DHI-NVR4108HS-8P-AI/ANZ used in our kits.
Q.10
Will it work with a non-Dahua NVR?
Yes — it is ONVIF conformant (Profile S, G and T). You keep video and basic motion events; SMD classification and the light-and-siren event linkage need a Dahua AI NVR.
Q.11
Can I use this camera without an NVR?
You can — it takes a MicroSD card up to 512GB (not included), streams to the DMSS app, and the deterrence features work stand-alone. Most buyers still pair it with an NVR for longer retention and AI search; treat the SD slot as backup.
Q.12
Can I talk through the camera from my phone?
Yes — dual built-in microphones and a speaker give genuine two-way talk through the DMSS app: hear what's happening and speak to whoever is there, live.
Q.13
Is a Dahua camera safe to use in Australia?
Dahua equipment was removed from federal government sites in 2023 as a precaution, and there is no restriction on private or business use. This camera does not need a cloud account: it records to your NVR, works fully offline, and supports HTTPS and firmware encryption. If you want zero outbound traffic, put the system on an isolated network — it still records locally.
Q.14
Which 3849 bullet should I buy?
Five bullets share the red and blue lights and siren voices. The S2 is the current TiOC 3.0 pick with SMD 4.0 and AcuPick support. The PRO is the night flagship — colour to 0.0004 lux and 50 metres of illumination, with the strongest speaker in the range. The ZAS adds a motorised 2.7–13.5mm zoom for gates and long driveways. The ANZ is the previous TiOC 2.0 generation — still SMD 4.0 and two-way talk, without AcuPick. The S3 is the oldest and cheapest path in, on SMD 3.0 without two-way talk.
Q.15
What warranty coverage applies in Australia?
The camera includes a 3-year warranty covering defects. Installation labour is not covered.

Pair with fixed cameras
Typical layout: fixed S2 bullets or S2 turrets on the building, this ZAS on the gate — one NVR, identical AI behaviour at both distances.

Use the bundle builder on this page to pair the camera with a 4, 8 or 16 channel Dahua AI NVR and a surveillance drive in one order.
Dark rather than distant?
The TiOC PRO bullet holds colour at 0.0004 lux with 50m illuminators — the pick when the problem is darkness, not framing.
