Dahua HDBW3449R-ZS-IL 4MP WizSense Smart Dual Light Dome 2.7-13.5mm motorised zoom lens
Strengthen your security straight away with the Dahua HDBW3449R-ZS-IL. This compact, vandal-resistant dome delivers a sharp 4MP image, smart detection and clear night vision. Thanks to the motorised zoom, you can adjust the viewing angle directly without needing a ladder.
What this camera does
The HDBW3449R-ZS-IL combines a high resolution with WizSense AI for fewer false alarms. The Smart Dual Light technology switches automatically between invisible infrared and warm white light. When motion is detected, you therefore get a colour image with detail, without needlessly lighting up your surroundings. The 2.7-13.5 mm motorised zoom lens (5x optical zoom) offers a wide overview angle through to precise close-ups, while H.265+ saves you storage and bandwidth. The robust metal housing (IP67/IK10) is built to withstand the weather, and the built-in microphone records clear sound.

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.
