Dahua DH-IPC-HFW3849T1-ZAS-PV-ANZ-S2 — 8MP 4K TiOC 3.0 Motorised Vari-Focal AcuPick Bullet
The Dahua DH-IPC-HFW3849T1-ZAS-PV-ANZ-S2 is Dahua's flagship long-range 4K TiOC bullet — the same red/blue strobe, siren and voice deterrence chain and same AcuPick AI as the fixed-lens 3849T1, but with a remotely-adjustable 2.7–13.5 mm zoom lens and extended 50 m IR + 40 m warm-light illumination. The integrated bullet sun shield protects the lens from glare and rain on exposed installs; the long zoom and longer illuminators turn a single camera into both a wide-angle perimeter shot and a high-zoom evidence camera. At telephoto it will detect motion at 257 m, recognise a person at 51.5 m, and identify a face at 25.7 m — three times the identification range of the fixed-lens 3849T1.
Combined with AcuPick attribute target search, SMD 4.0, 120 dB WDR, EIS image stabilisation, AI Coding (≥25% extra compression), two-way audio and full TiOC 3.0 active deterrence, this is the camera Australian installers reach for on long rural driveways, large commercial yards, mining sites, carparks and any pole-mount scenario where remote zoom flexibility and identification at distance matter. Available in White (DH-IPC-HFW3849T1-ZAS-PV-ANZ-S2) and Black (DH-IPC-HFW3849T1-ZAS-PV-ANZ-S2-BLK). Australian stock with 3-year warranty.

Why Choose the Motorised Vari-Focal 8MP Bullet
The vari-focal upgrade matters when one camera needs to do two jobs — cover a wide approach and pull tight on a number plate or face at the end of a long driveway. Where the fixed-lens 3849T1 bullet commits to a single 106° field of view forever, the ZAS lets you dial the zoom remotely after install. Combined with the bullet's integrated sun shield, longer chassis and pole-mount-friendly silhouette, this is the camera Australian installers reach for on rural driveways, large commercial yards, mining sites, carparks and any site where field-of-view requirements change over time.
2.7–13.5 mm Motorised Vari-Focal
Five times optical zoom with remote focus and zoom control via DMSS or a Dahua NVR. Set the field of view once at install, then re-tune from your phone whenever the scene changes — no ladder, no scaffolding, no re-aiming.
Massive DORI Reach at Tele
At maximum zoom the 3849T1 ZAS will detect motion at 257 m, recognise a person at 51.5 m, and identify a face at 25.7 m — nearly three times the identification range of the fixed-lens 3849T1 bullet. One camera secures a footy-field-sized property.
50 m IR + 40 m Warm Light
Extended Smart Dual-Light reach matches the longer optical range — IR illumination out to 50 m, warm-light LED to 40 m. Enough to fully illuminate a long driveway or a typical carpark in pitch darkness.
Integrated Sun Shield & Bullet Body
The bullet sun visor cuts harsh Australian glare from the lens, reduces ghosting on backlit scenes, and keeps rain off the front element — critical for the unsheltered pole and gable mounts where long-range bullets typically end up.
TiOC 3.0 — Three-in-One Active Deterrence
Same active deterrence chain as the fixed-lens 3849T1: red/blue strobe, on-board siren and custom voice broadcast fire automatically the moment SMD 4.0 confirms a human or vehicle.
EIS + AI Coding
Electronic Image Stabilisation (EIS) corrects subtle vibration on long-zoom shots from a pole or gable. AI Coding delivers ≥25% extra compression efficiency over Smart H.265+ — longer retention on the same NVR drive.
Smart Features for Real-World Australian Sites
Dahua TiOC 3 & PRO Webinar 2024 — Official English Walkthrough
Remote Zoom & Auto-Focus
Adjust the 2.7–13.5 mm zoom from the DMSS app or a Dahua NVR. The motor handles focus automatically as the lens zooms — no manual focus turret to fiddle with at the camera.
IVS Tripwire & Intrusion Zones
Define a virtual line across the driveway or a no-go zone around the shed — get a notification (and trigger the deterrence chain) only when a human or vehicle actually crosses it.
Two-Way Audio & Custom Voice
Dual built-in MICs and a 1-channel speaker support live two-way talk via DMSS or a Dahua NVR. Pre-loaded plus uploadable voice files let you record a site-specific warning in your own voice.
Edge Recording — MicroSD
On-camera MicroSD records days of 4K footage independently of the NVR — a critical redundancy layer if the network drops, the recorder is stolen or power is cut.
One-Press Arming / Disarming
A single tap in the DMSS app arms or disarms the full TiOC chain. Disarm for parties and deliveries; rearm with one button for overnight and holidays.
Plug & Play + Third-Party VMS
Drops into any Dahua NVR via plug-and-play, and works over ONVIF Profile S/G/T with Milestone, Genetec, Hanwha WAVE, ExacqVision, Blue Iris and Synology Surveillance Station.
Pair with a Dahua 5-Series NVR for the Full AcuPick Experience
SMD 4.0, IVS rules, two-way audio and the full TiOC 3.0 deterrence chain all run on-camera — they work with any Dahua AI NVR, or even an ONVIF third-party recorder. But to unlock AcuPick — attribute-based human and vehicle target search, similar-image cross-camera tracking and AI-accelerated playback — you need a compatible Dahua 5-Series AcuPick NVR. With a long-zoom 4K bullet, the AcuPick payoff is even bigger: the long-tele footage carries enough pixel density for clean facial-attribute search at distance.

3849T1-ZAS (Motorised) vs 3849T1-AS (Fixed) — Which 8MP Bullet Should You Choose?
Both cameras run the same TiOC 3.0 active deterrence chain, the same AcuPick AI, the same Smart Dual-Light system and the same 4K image quality in the same bullet chassis. The deciding question is the lens: do you need a single fixed field of view, or the flexibility to zoom in remotely? If the site has long sightlines, changing conditions, or you want one camera to cover both wide approach and high-zoom evidence, choose the ZAS. If you only need a fixed 106° wide view and the budget is tight, the fixed-lens 3849T1 is the cheaper pick.

Frequently Asked Questions
What does the "ZAS" in 3849T1-ZAS mean?
"Z" stands for motorised zoom — this is the motorised vari-focal lens bullet version. "AS" = audio + alarm I/O (built-in MIC, speaker, alarm in/out). The fixed-lens equivalent is the 3849T1-AS-PV-ANZ-S2. Both share the same chassis, AcuPick AI, TiOC 3.0 deterrence and Smart Dual-Light; the ZAS adds a 2.7–13.5 mm zoom lens with auto-focus you can drive remotely.
Is the motorised vari-focal bullet worth the extra cost?
If the site has long sightlines (driveways, perimeters, carparks) or if field-of-view requirements are likely to change (new fences, vegetation, signage), yes — the ability to remotely re-zoom from the app saves a service call every time. For a fixed shopfront or a narrow doorway, the fixed-lens 3849T1 bullet is the cheaper choice.
Can the camera pan and tilt remotely too, or just zoom?
The 3849T1-ZAS is a motorised vari-focal bullet, not a PTZ. The lens supports remote zoom and auto-focus, but the camera body itself does not pan or tilt remotely — the housing is aimed manually at install time. For a fully remote pan/tilt/zoom camera, look at a Dahua PTZ.
How does the ZAS bullet compare to the ZAS turret?
Same internals, different form factor. The bullet has an integrated sun shield, longer chassis and more visible silhouette — better for poles, gables and exposed eaves. The turret is more compact and discreet for wall-flush installs. Both share the same 5× motorised zoom, 50 m IR, AcuPick AI and TiOC 3.0 deterrence.
Do I need a special NVR for AcuPick?
Yes — AcuPick target search requires a compatible Dahua 5-Series AcuPick NVR. The TiOC 3.0 deterrence chain, SMD 4.0, IVS and two-way audio all work on any Dahua AI NVR. Shop AcuPick NVRs here →
How much PoE budget does this camera need?
The ZAS bullet draws a maximum of 9.8 W on PoE when the motor, strobe, siren and warm light are simultaneously active — well within the 802.3af PoE budget of 15.4 W. Most installs sit at 5–6 W in normal operation. Make sure your PoE switch budgets for the peak, especially on multi-camera switches.
Will the camera deter intruders automatically?
Yes. The TiOC 3.0 deterrence chain fires the instant SMD 4.0 confirms a human or vehicle inside the rule zone — strobe lights, siren and voice broadcast all run on-camera, 24/7, without any operator, NVR command or mobile-app interaction.
What is the difference between the White and Black versions?
Specifications are identical. DH-IPC-HFW3849T1-ZAS-PV-ANZ-S2 is white; DH-IPC-HFW3849T1-ZAS-PV-ANZ-S2-BLK is black. Choose black for dark eaves, charcoal fascia and modern industrial aesthetics; white for traditional cream/render walls.
Will it keep recording if the NVR or internet goes down?
Yes. The on-board MicroSD slot accepts cards up to 512 GB and records 4K footage independently of the NVR. Combined with DMSS cloud push notifications, you have three redundant recording paths: NVR, MicroSD and event clips to your phone.
Is the camera suitable for Australian outdoor conditions?
Yes. It is rated IP67 and −30 °C to +60 °C — comfortably covering every Australian climate from a Hobart winter to a Karratha summer. The metal + reinforced-plastic housing and ±30% wide-voltage tolerance also handle dirty mains power common on rural sites.
Does it work with Hikvision NVRs or third-party VMS?
Basic recording, streaming and motion work over ONVIF Profile S/G/T on most third-party NVRs and VMS platforms (Milestone, Genetec, Hanwha WAVE, ExacqVision, Blue Iris, Synology). However, TiOC deterrence, AcuPick, SMD 4.0 and two-way audio require a Dahua NVR or DMSS to be triggered correctly.
What is the warranty and where is it serviced?
This camera ships with a 3-year Australian Dahua warranty, serviced back-to-base by Dahua Australia. CCTV Guru handles the entire RA process and provides Australian-based technical support for the life of the product.
