Dahua HDBW3449R-ZS-IL-BI Black 4MP WizSense Smart Dual Light Dome 2.7-13.5mm motorised zoom lens
This black dome camera delivers razor-sharp 4MP images, switches smartly between infrared and warm white light for clear colours 24/7 and reduces false alarms with smart AI. Thanks to the motorised zoom lens, you can easily adjust the field of view remotely, while the robust housing performs year after year, indoors and outdoors.
What this camera does
The Dahua HDBW3449R-ZS-IL-BI combines smart lighting, AI recognition and motorised zoom in one compact dome. The Smart Dual Light technology switches automatically between unobtrusive infrared and warm white light. This gives you clear faces and number plates in colour at night as well, when it matters. WizSense with SMD 4.0 recognises people and vehicles, so alerts are more relevant and you spend less time on false alerts. The sturdy metal housing is weatherproof and vandal-resistant, so your camera keeps protecting, even under harsh conditions.
- 4MP 1/2.9″ CMOS sensor for sharp, detailed images (up to 2688×1520 at 25/30 fps).
- Varifocal motorised zoom lens 2.7-13.5 mm (F1.4) with autofocus: from a wide overview angle to zooming in on detail.

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.
