Dahua HDBW3849E-AS-IL 8MP WizSense Smart Dual Light Dome 2.8mm lens
This 8MP dome is robust and packed with smart functions. Thanks to Smart Dual Light, it records discreetly with infrared at night by default and, when people or vehicles are detected, switches immediately to warm white light for clear colour images. The result: more detail, less guesswork and quick identification when it matters.
What this camera does
The Dahua HDBW3849E-AS-IL 8MP WizSense Smart Dual Light Dome delivers 4K quality for every scenario. The fixed 2.8 mm wide-angle lens gives a broad overview, while the AI functions reduce false alarms.
- 8MP 1/2.7″ CMOS sensor with high sensitivity for sharp, clear images in low light.
- Maximum resolution 3840 × 2160 (4K) at up to 25/30 fps for smooth and detailed video playback.
- Smart Dual Light: automatic switching between infrared and warm white light for optimal night vision performance and colour images on relevant detection.
- AI-based perimeter protection (WizSense): accurate detection of people and vehicles, fewer false alerts.
- SMD 4.0 for intelligent motion detection with greatly reduced false alarms.
- Fixed 2.8 mm lens with a wide viewing angle; ideal for entrances, halls, shop floors or car parks.
- H.265 compression saves storage space and bandwidth without visible loss of quality.
- Built-in microphone for synchronised sound with the video images; microSD slot up to 512 GB for local recording.
- IP67 weatherproof and IK10 vandal-resistant: designed for long-term, trouble-free use both indoors and outdoors.
- Wide dynamic range (WDR) for a clear image in backlit and challenging lighting conditions.
- Power over Ethernet (PoE) for quick, tidy installation with a single network cable; 12V DC is also supported.
- Night vision over a long distance with IR and white light (depending on the environment), so you can see everything in the dark as well.

Frequently asked questions
Do I need a separate power supply?
No, with PoE, power and video run over the same network cable. Your recorder or switch must then supply PoE. If it does not, the camera can run on a separate 12 V power supply.
Can I record without a recorder?
Yes, a microSD card of up to 512 GB fits in the camera. Convenient for a single camera. If you want to review footage over a longer period or view several cameras together, a recorder is the better choice.
Can this camera be mounted outdoors?
Yes. The housing is IP67 and IK10 and is therefore made for outdoor use. Mount it with screws and plugs, and feed the cable through the supplied cable gland so that no moisture reaches the connection.
Does the camera work with my phone?
Yes, with the free Dahua DMSS app you can watch live, play back recordings and receive notifications. The link to the app is under the Downloads tab.
Which mounting parts do I need?
That depends on the surface. The parts that Dahua lists for this model are shown under "Frequently bought together" on this page. If you are unsure, call or email us and we will help you check.
