Dahua 8MP IPC-HDW3867EM-S-IL-ANZ Smart Dual Light Fixed-focal Eyeball WizSense Network Camera

Smart Dual Light

A multi-core illuminator carrying both infrared and warm white LEDs, each reaching 30 m, with automatic or manual control. Infrared runs as the quiet baseline; the warm light fires on confirmed detection to deliver full-colour capture of the event. Colour when it counts, darkness the rest of the night.

8MP 4K Resolution

3840 × 2160 at up to 25/30 fps, with everything from 6MP down to CIF available as alternative streams. The practical value of 4K is crop headroom — you can zoom hard into a corner of a frame during review and still have real image data rather than a block of pixels.

SMD 4.0 Classification

Deep learning that decides whether motion came from a person, a vehicle, or something you do not care about — before any alert is sent. Possums, gum leaves, shifting shadows and insects near the lens are discarded. On this camera it does double duty, because it also decides when the warm light fires.

AcuPick AI Target Search

The camera generates appearance metadata as it records. Working with a compatible Dahua NVR, that lets you search live and recorded footage for a specific person or vehicle by their characteristics rather than scrubbing a timeline — turning an afternoon of review into a few seconds.

Perimeter Protection Zones

Tripwire and intrusion rules, both with human and vehicle classification applied. Draw a line across a side gate or a zone around a shed and be alerted only when a classified target actually crosses it — filtering by what moved and where it went, not simply that something moved.

Wide F1.4 Aperture

F1.4 is a genuinely wide aperture for a fixed-lens camera and it does real work: more light through the glass means less digital gain is required, which means cleaner images rather than the smeary noise typical of low-light footage. Colour holds to 0.007 lux, monochrome to 0.0007 lux.

AI SSA and 120 dB WDR

AI Scene Self-Adaptation adjusts image parameters in real time to suit conditions rather than holding a fixed profile. Paired with 120 dB WDR, HLC, BLC, 3D noise reduction and defog, it keeps quality consistent across the changeable conditions that defeat cheaper cameras — backlit doorways, wet roads, low winter sun.

AI Coding and Three Streams

Smart H.265+/H.264+ plus Dahua's AI coding, which analyses scene content to cut bitrate further again — genuinely important at 4K, where storage costs scale fast. Three simultaneous streams let you record at full resolution while viewing remotely at 1080p.

512 GB Edge Storage

Double the card capacity of most cameras in this class, which matters at 8MP where files are large. Enough for genuine standalone operation on an outbuilding or gate, or as a backup layer so footage survives on the camera if the recorder is stolen or drops offline. FTP, SFTP and NAS storage also supported.

Full Angle Adjustment

Pan and rotate through a full 360° with 80° of tilt, so the camera can be aimed and levelled properly from an angled eave, a corner or a soffit that does not sit square to the area of interest. Fewer installations end up with a crooked horizon because the bracket would not cooperate.

Metal IP67 Housing, −40°C to +60°C

A metal body rated fully dust-tight and sealed against water, specified across a temperature range far beyond anything an Australian site produces — coastal, tropical, inland or a metal roof cavity in January. Compact at 105.5 mm and 0.53 kg.

Low-Draw PoE and Strong Cyber Security

802.3af PoE at 9.5 W maximum, or 12 V DC — easy on a shared switch budget across a multi-camera system. Video, firmware and configuration encryption, HTTPS, 802.1x, IP/MAC filtering, account lockout and trusted boot are all supported, which matters more than most buyers realise on an internet-connected device.

Home Driveways and Front Entries

The use case Smart Dual Light was designed for. At eave height facing the driveway, the camera sits quietly on infrared all evening and lights up in colour only when someone actually arrives — capturing vehicle colour, clothing and faces while acting as a deterrent in the same moment. Mount so visitors pass within 8–10 m for identification-grade detail.

Gates, Side Access and Rear Boundaries

The quiet points around a property are where people actually get in, and they are usually the least covered. A tripwire across a gate line with human classification produces clean, targeted after-hours alerts rather than reporting every cat and every gust of wind through the hedge.

Shopfronts and Small Commercial

Entry points are the hardest lighting problem in retail — bright outside, dim inside, subject in between. 120 dB WDR and AI SSA keep faces visible rather than reducing them to silhouettes, while 4K resolution gives enough detail to review a counter incident with confidence rather than guesswork.

Warehouses, Yards and Loading Areas

High-value stock sitting unattended overnight benefits from geography-based triggers rather than raw motion. An intrusion zone around a compound or a tripwire across a roller door produces targeted events, and colour capture at the moment of detection gives you something concrete rather than a grey shape.

Harsh and Exposed Environments

A metal IP67 housing rated −40°C to +60°C at 95% humidity covers rooftops, coastal walls, tropical humidity and inland dust. If you have replaced cameras prematurely on a salt-exposed or high-UV site, the housing specification here is a meaningful part of the value rather than a line on a datasheet.

Strata and Apartment Common Areas

Shared entries, lifts, bin areas and car parks generate disputes as often as incidents, and both need evidence. 4K detail plus AcuPick search means a building manager can retrieve the relevant clip quickly rather than spending an afternoon on it — which is what determines whether the system gets used at all.

Choose this model if…

• You want maximum crop headroom for reviewing footage after an incident.
• You want colour capture of detected events without a light running all night.
• False alerts are your main frustration and you want on-camera AI classification.
• You review footage often enough that AcuPick search would save real time.
• The site is reasonably lit, or you are relying on the 30 m illumination.
• Your recorder handles 8MP per channel and you have the drive capacity.
• The position is exposed and the metal −40°C to +60°C housing matters.

Choose a different model if…

• The site is genuinely dark and low-light performance matters more than pixel count. The 6MP version of this camera has a better low-light rating on the same sensor.
• You want active deterrence. This has a microphone only — no speaker, no strobe, no siren. A TiOC model adds light and audio warning on detection.
• You want unbroken colour all night regardless of activity. This is dual light — colour on detection. WizColor runs colour continuously.
• You need to adjust framing after mounting. Fixed lens — a motorised varifocal gives on-site flexibility and remote zoom.
• You need readable plates on moving vehicles at distance. See the DORI table — that is a dedicated ANPR job.
• You need two-way voice. Microphone only; there is no speaker for talkback.

How far away can this camera identify someone?

Around 8.5 m on the 2.8 mm lens, or 9.9 m on the 3.6 mm. Those are Dahua's published Identify figures under the DORI standard, and Identify is the band that covers recognising a stranger or reading a plate. The much larger 84.8 m figure you will see quoted is the Detect range, which only means registering that something is present. Both numbers are accurate; they describe different things. Mount for the job you actually need — see the DORI table above.

Is 8MP better than 6MP?

For daylight detail and crop headroom, yes. For low light, not necessarily. Both this and the 6MP version use a 1/2.7″ sensor, so fitting 8 million pixels onto it means each pixel is smaller and gathers less light. The published minimum illumination reflects that: 0.007 lux here against 0.005 lux on the 6MP. If your site is reasonably lit or you are relying on the illuminators, choose 8MP. If it is genuinely dark, the 6MP may serve you better.

How does Smart Dual Light work?

In normal low-light conditions the camera runs infrared only, recording in monochrome and emitting no visible light. When SMD 4.0 confirms a human or vehicle, the warm white LEDs switch on and the footage becomes full colour for the duration of that event, then reverts to infrared. Both illuminators reach 30 m. The effect is colour evidence at the moments that have evidentiary value, without running a white light all night.

Does it record in colour all night?

Only during detection events. Between them it sits on infrared and records greyscale. For most residential and small business use that is the better arrangement — you get the colour evidence without a floodlight above the driveway from dusk to dawn. If you need a continuous colour record regardless of activity, that is a WizColor camera and we can point you to one.

Does it have a speaker or siren?

No. There is a built-in microphone for audio recording, but no speaker, no strobe and no siren — so no two-way talk and no active deterrence. If you want the camera to warn people off rather than simply record them, look at the Dahua TiOC range, which adds red and blue strobe, a siren and two-way audio to the same AI detection.

What is SMD 4.0 and how does it cut false alarms?

Ordinary motion detection compares one frame against the next and triggers on any change — a branch, a shadow, a moth near the lens, headlights sweeping a fence. SMD 4.0 runs a deep learning model that recognises the shape and movement signature of humans and vehicles specifically, and discards the rest before an alert is generated. On this camera it also controls when the warm light fires, so accuracy matters twice over.

What is AcuPick and do I need a particular NVR?

AcuPick tags recorded targets with appearance metadata so footage can be searched by what someone or something looked like, rather than by scrubbing through time. The tagging happens at the camera, but the search interface lives in the recorder and requires a compatible Dahua NVR. On any other recorder the camera records normally and you simply do not get the search. Confirm your NVR before ordering if AcuPick is part of why you are choosing this model.

2.8 mm or 3.6 mm — which lens should I choose?

Start from the shape of the area rather than its size. The 2.8 mm gives 110° horizontally and suits wide, shallow spaces viewed from close range — courtyards, carports, general perimeter, indoor rooms. The 3.6 mm gives 86° and concentrates the same 8MP across a narrower field, which suits a long driveway, gate or defined approach. The 3.6 mm also extends every DORI figure, including identification from 8.5 m to 9.9 m. The lens is fixed, so this is decided at order time.

How much storage will four of these use?

Considerably more than a 1080p or 4MP system — that is the practical cost of 4K. AI coding and H.265+ offset much of it by lowering bitrate during static periods, but not all. If you have a retention target in mind, tell us the camera count, resolution and frame rate and we will size the drive properly rather than guessing.

Can I use it without an NVR?

Yes — a microSD card up to 512 GB supports continuous or event-triggered recording on the camera itself, viewable through the DMSS app, and FTP, SFTP and NAS storage are also supported. That makes it genuinely viable as a standalone unit. Use a surveillance-rated or high-endurance card; standard consumer cards are not designed for continuous writing and typically fail within months.

What power does it need?

Standard 802.3af PoE over a single Cat5e or Cat6 run, drawing 5.3 W typically and 9.5 W maximum with everything active. That low consumption makes it easy to fit several onto a shared switch. 12 V DC is available as an alternative. Use solid copper cable rather than copper-clad aluminium on longer runs — CCA is a common cause of intermittent PoE dropouts.

Is it legal to record audio in Australia?

Surveillance device laws are set at state and territory level and they differ meaningfully. As a general principle, recording private conversations without any party's knowledge is restricted. Entrances, external perimeters, yards and commercial premises with clear signage are usually the appropriate places to enable audio. Check the legislation applying in your state — in Victoria this is the Surveillance Devices Act 1999 — before switching the microphone on, and seek legal advice where the site is a workplace, shared or publicly accessible.

Will it cope with harsh Australian conditions?

Yes. IP67 means fully dust-tight and sealed against water immersion, and the metal housing is rated from −40°C to +60°C at up to 95% humidity — covering rooftop heat, tropical humidity, coastal salt air and inland dust. The rating applies to the camera body, so seal the cable entry and use a weatherproof junction box for any termination, because that join rather than the housing is where outdoor failures almost always begin.
