Dahua HFW3849E-AS-IL 8MP WizSense Smart Dual Light Bullet 2.8mm lens
This 8MP WizSense bullet combines razor-sharp 4K resolution with smart AI detection and Smart Dual Light. That means colour images when it matters, black-and-white infrared when that is the better choice, and far fewer false alerts. Sturdy, weatherproof and easy to install via PoE, ready for any situation, at home or in business.
What this camera does
The Dahua HFW3849E-AS-IL delivers immediate results: more detail, better detection and lower costs. Thanks to H.265 compression, you save storage and bandwidth without compromising on quality. The advanced WizSense AI recognises people and vehicles, so you only receive alerts that matter. The Smart Dual Light switches automatically between discreet infrared and bright white light for a clear colour image when movement is detected. With the built-in microphone, local storage up to 512 GB and a robust IP67/IK10 housing, you can rely on a durable, complete security solution.

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.
