Make your site safer straight away with the Dahua HDW3649T-ZS-IL-BI. This powerful 6MP security camera delivers razor-sharp images, day and night. Thanks to Smart Dual Light, the camera switches intelligently between discreet infrared and bright white light.
What this camera does
The motorised zoom lens (2.7-13.5 mm) with autofocus captures everything from overview to close-up, without manual focusing. WizSense AI recognises people and vehicles very accurately and filters out disruptive movement such as leaves or pets. With Starlight technology and the powerful Dual Light performance, you see everything clearly and in colour, even in the dark. The robust IP67 housing withstands weather and wind, while H.265 compression keeps your storage and data costs low. Connect the camera directly to your recorder, NAS or VMS via ONVIF S/G/T and view live images on the move with the free DMSS app. Convenient to use, with strong results for a fair price.

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 up to 256 GB fits in the camera. Handy for a single camera. If you want to look back further or view several cameras together, a recorder is the better choice.
Can this camera be mounted outdoors?
Yes. The housing is IP67 and therefore suitable for outdoor use. Mount it with screws and plugs, and route 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.
