What this camera does
With this PTZ camera you can easily monitor large sites, car parks or industrial units. Thanks to Starlight you see more in low light, while True WDR copes with strong backlight situations. Auto Tracking automatically follows people or vehicles, and with the 25x zoom you can bring out details that serve as evidence. The robust housing, smart IR illumination and PoE+ power make installation simple and durable. This is an exclusively strong combination of value, reliability and performance.

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 IP66 and is therefore made for outdoor use. Mount it with screws and wall 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.
