Description

One camera, wall to wall.
4MP, 180° view, IK10 metal dome.
This is the DH-IPC-HDBW3466R-AS-P: a vandal-rated dome with a 2.1 mm lens that sees 180° across, so one camera on a wall covers a whole room, shopfront or yard. EPTZ zooms in on the people and vehicles that trip an alarm while the full view keeps recording.
In one sentence: the DH-IPC-HDBW3466R-AS-P is a Dahua WizSense 3 Series 4MP wide angle dome with a 2.1 mm F2.0 lens covering 180° (170° with distortion correction on), 15 m IR, SMD 3.0, tripwire and intrusion with human and vehicle sorting, EPTZ, 1 audio and 1 alarm in/out, a built-in mic, IP67, IK10 and PoE.
Camera only. Recorder and cabling are separate.
This listing is one camera. It needs PoE or a 12 V supply for power, and somewhere to store the footage.
- DH-IPC-HDBW3466R-AS-P dome camera
- A PoE NVR or a PoE switch, or a 12 VDC supply
- Cat5e or Cat6 cable to the camera
- A recorder, NAS or microSD card (up to 256 GB) for the footage
Mount it on the wall, see the whole space.
The 2.1 mm lens sees 180° with distortion correction off, or 170° with it on (the default, which straightens the edges). Put it in the middle of a wall and it covers both corners.

Lens and IR
2.1 mm, F2.0, starlight sensor.
A 1/2.7" starlight-grade sensor records 4MP (2688 × 1520) at up to 25/30 fps, or 5MP (2880 × 1620) at 20 fps. Colour holds down to 0.01 lux at F2.0, three IR LEDs reach 15 m, and 120 dB WDR handles bright doorways.

Housing
Metal, IP67 and IK10.
94 mm high, Ø 122 mm and about 500 g. IK10 means it survives a 20 J impact, and IP67 keeps out dust and water. Runs from −40 °C to +60 °C.
How it goes in
From cable to first alert.
01
Run one cable
Cat5e or Cat6 to a PoE NVR or switch. The camera draws up to 7.7 W on PoE. A 12 VDC 1 A supply also works.
02
Fix the base
Three Ø 4.5 mm screw holes on a 110 mm circle. Mount it centred on the wall you want to look out from, then tilt the lens (0–80°).
03
Add it and set the view
Add it to a Dahua NVR, DSS, Smart PSS or the DMSS app. Leave distortion correction on for straighter edges, or turn it off for the full 180°.
04
Set the rules
Turn on SMD 3.0, or draw tripwire and intrusion zones for people, vehicles or both. EPTZ then zooms in on whatever trips them.

Pair it with
What this camera does not include
Recorder
A Dahua WizSense PoE NVR
Powers and records the camera on one cable and adds Smart Search through the SMD and tripwire events.
Power
A PoE switch
If the recorder has no free PoE ports. Allow 7.7 W for this camera.
Cabling
Cat5e or Cat6 cable
One run per camera, up to the usual 100 m Ethernet limit.
Mounting
Dahua PFA137 junction box bracket
Dahua's optional box for this dome. It hides the cable joint and the audio and alarm leads. PFB220C ceiling, PFB2203W wall and PFA152-E pole mounts are also listed.
Where it is used
Where a 180° dome fits.
Shops
One camera on the back wall covers the whole floor, counter to door.
Classrooms and offices
Mounted mid-wall, it sees both corners of the room.
Hallways and lobbies
At a T-junction it covers both directions at once.
Back yards
Under the eave, from one fence to the other.
Warehouses
Loading docks and aisles, with tripwire on the door line.
Car parks and driveways
Close-in coverage of a wide area. For number plates use a narrower lens.
Distortion correction on or off

| Vertical view | 75° | 78° |
| Diagonal view | 175° | 180° |
| Straight lines at the edges | Corrected | Curved (fisheye look) |

Common questions
Is a recorder included?
No. This listing is the camera only. It records to a Dahua NVR, a NAS or a microSD card of up to 256 GB.
Does it really see 180°?
Yes, with lens distortion correction off it covers 180° across and 78° up and down. With correction on (the default) the edges are straightened and the view is 170° across.
How is it powered?
By PoE or 12 VDC. It draws up to 7.7 W on PoE or 6.4 W on 12 VDC with IR on.
How far does it see at night?
Its three IR LEDs reach up to 15 m. In colour it works down to 0.01 lux at F2.0, and with IR on it records at 0 lux.
How far away can it identify a person?
Dahua rates it to identify a person at 5.2 m, recognise at 10.4 m and detect movement out to 52 m. A wide lens trades distance for coverage.
What is EPTZ?
Electronic pan, tilt and zoom. When people or vehicles set off an alarm the camera zooms in on them digitally and tracks them, while still giving you the full wide view.
Which smart rules does it have?
SMD 3.0, plus tripwire and intrusion, each able to sort humans from vehicles. Dahua does not list face detection for this model.
What are the audio and alarm connections for?
The audio out (RCA) drives an amplified speaker, the audio in takes an external mic, the alarm in takes a sensor contact and the alarm out can switch a siren or light.
Will it work with a non-Dahua recorder?
It supports ONVIF Profile S, G and T, so most ONVIF recorders can record it. Smart Search needs a Dahua Smart NVR.
Is it vandal resistant?
Yes. It is rated IK10 (a 20 J impact) and IP67, with a metal casing, and runs from −40 °C to +60 °C.
What size is it and how does it mount?
94 mm high and Ø 122 mm, 500 g. The base has three Ø 4.5 mm screw holes on a 110 mm circle. The lens pans 0–355°, tilts 0–80° and rotates 0–355°.
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.

Installation and safety
Low-voltage camera. PoE (up to 7.7 W) or 12 VDC (up to 6.4 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. Recording conversations is covered by state and territory surveillance laws. Check them, and use signage, before you switch the microphone on.
What it does not do. No zoom lens, no built-in speaker or siren (use the audio or alarm output), no white light and no Wi-Fi.
