Description

8MP that lights up and speaks up.
Smart dual light, siren and two-way talk.
This is the Australian ANZ-S2 version of Dahua's 8MP TiOC bullet: an F1.0 camera that switches from IR to warm light when a person or vehicle walks in, flashes red and blue, and plays a warning through its own speaker.
In one sentence: the DH-IPC-HFW3849T1-AS-PV-ANZ-S2 is a Dahua WizSense 3 Series 8MP fixed bullet with an F1.0 lens, smart dual light (30 m IR and 30 m warm light), red and blue strobe, siren, two-way audio, SMD 4.0 and PoE.
Camera only. Recorder and cabling are separate.
This listing is one white camera. It needs PoE or a 12 V supply for power and somewhere to store the footage. It is listed with the 2.8 mm lens; Dahua also makes a 3.6 mm lens under the same code, so confirm with us which lens is in stock when you order.
- DH-IPC-HFW3849T1-AS-PV-ANZ-S2 bullet camera
- A PoE NVR or 802.3af PoE switch, or a 12 VDC supply
- Cat5e or Cat6 cable to the camera
- A recorder, NAS or microSD card for the footage
It sees, then it reacts.
At night the camera runs on IR. When SMD 4.0 or a tripwire or intrusion rule picks up a person or vehicle, it turns on its warm light so the clip is in colour, flashes red and blue, and can sound a siren or a recorded voice message. Animals and moving leaves are filtered out, so the alarms you get are worth looking at.

Front
Two kinds of light and a strobe.
Two IR LEDs and two warm lights each reach up to 30 m. The red and blue light above the lens is the visual warning. Colour image down to 0.004 lux at F1.0, black and white to 0.0004 lux, and 0 lux with the lights on.

Lens
8MP at full frame rate.
3840 × 2160 at up to 25/30 fps through an F1.0 lens on a 1/2.7" sensor. The 2.8 mm lens covers 106° across and detects people out to 66 m (DORI).

Housing
IP67, metal and plastic, three-axis bracket.
288.4 × 94.4 × 84.7 mm and 1.0 kg. Pan 0–360°, tilt 0–90° and rotate 0–360° to line up the view. Rated IP67 and −40 °C to +60 °C.
How it goes in
From cable to first warning.
01
Run one cable
Cat5e or Cat6 to a PoE NVR or an 802.3af PoE switch. Allow up to 9.4 W per camera on PoE. 12 VDC also works.
02
Fix the bracket
Screw the base to the wall or eave, then pan, tilt and rotate the bullet to frame the scene.
03
Add it to the recorder
Initialise the camera, then add it to a Dahua NVR, Smart PSS Lite, DSS or the DMSS app on your phone.
04
Set the rules and the warning
Draw tripwire or intrusion zones, tick human and vehicle, then choose the light, siren or voice message it plays.

Pair it with
What this camera does not include
Recorder
A Dahua AI NVR
Powers and records the camera on one cable, and unlocks Smart Search, Quick Pick and AcuPick for people and vehicles.
Power
An 802.3af PoE switch
If the recorder has no PoE ports. Allow 9.4 W for this camera with the lights and siren on.
Cabling
Cat5e or Cat6 cable
One run per camera, up to the usual 100 m Ethernet limit.
Mounting
A junction box
Dahua lists the PFA135 junction box and PFA152-E pole mount for this camera, to hide the cable tail.
Where it is used
Where an 8MP deterrence bullet fits.
Driveways and front yards
Warm light and a voice warning when someone walks up at night.
Side gates and back yards
Tripwire on the gate line, with the strobe and siren as a first response.
Shops after hours
Shopfronts, rear doors and loading bays, with colour clips of every event.
Warehouses and yards
Human and vehicle sorting on roller doors and fence lines cuts false alarms.
Building sites
A visible strobe and recorded warning help turn people away before they come in.
Farms and sheds
SMD 4.0 filters animals, so the alarm means a person or a vehicle.

Common questions
What does TiOC mean on this camera?
Dahua groups this camera under TiOC 2.0: smart dual light for colour at night, active deterrence (red and blue light, siren and voice) and WizSense AI that sorts people and vehicles, in one camera.
Is a recorder included?
No. This listing is the camera only. It records to a Dahua NVR, a NAS, FTP or a microSD card in the camera.
How is it powered?
By 802.3af PoE or 12 VDC. It draws 5.8 W on PoE at rest and up to 9.4 W with the warm light, siren and analytics all running.
How far does it see at night?
The IR reaches up to 30 m and the warm light up to 30 m. In colour it works down to 0.004 lux at F1.0, and with the lights on it records at 0 lux.
Which lens is it, 2.8 mm or 3.6 mm?
It is listed with the 2.8 mm lens, which covers 106° across. Dahua also makes a 3.6 mm version under the same code (85° across), so confirm with us which lens is in stock when you order.
How does the active deterrence work?
When a tripwire, intrusion or SMD rule triggers, the camera can flash its red and blue light, sound a siren or play a voice message. Dahua includes several messages and you can import your own. One-tap disarming in the app turns the warnings off when you are home.
Can I talk through it?
Yes. It has built-in dual microphones and a speaker for two-way talk, plus one RCA audio input and one RCA audio output.
What size microSD card does it take?
Dahua's spec table for this exact model says up to 512 GB, but the summary on the same sheet still says 256 GB. A 256 GB card is the safe choice; ask us before buying a 512 GB card.
Will it work with a non-Dahua recorder?
It supports ONVIF Profile S, G and T, so most ONVIF recorders can record it. The light, siren and AI search features work best with a Dahua NVR.
Can it be mounted outside?
Yes. It is rated IP67 and runs from −40 °C to +60 °C at up to 95% humidity.
What warranty does it have?
Dahua gives its 3 Series network cameras a 3-year (36-month) manufacturer warranty under Dahua Australia's warranty policy. Claims are handled in Australia through InFront Technologies: call 1300 736 970 or email [email protected].
Who can install the cable?
Concealed data cabling to the camera is customer cabling under AS/CA S009 and needs an ACMA-registered cabler. Plugging a patch lead into an existing outlet does not.
Supported by InFront Technologies.
Help choosing the lens, recorder or switch: call 1300 736 970 or email [email protected]. The datasheet is on the Attachments tab.
Installation and safety
Low-voltage camera. PoE (802.3af, up to 9.4 W) or 12 VDC (up to 7.7 W). There is no mains connection on the camera. A new power point for a 12 V supply needs a licensed electrician.
Cabling. Concealed data cabling is customer cabling under AS/CA S009 and needs an ACMA-registered cabler.
Audio and sirens. Recording conversations is covered by state and territory surveillance laws, and sirens and lights may be subject to local council rules. Check them, and use signage, before you switch them on.
What it does not do. No Wi-Fi, no optical zoom and no face recognition. The lens is fixed.
