Dahua HDW3449T-ZS-IL, 4MP Smart Dual Light, WizSense, 2.7–13.5 mm Motorized Zoom Lens

The Dahua IPC-HDW3449T-ZS-IL is an advanced 4-megapixel IP turret camera from the WizSense series. Thanks to its smart AI features, Smart Dual Light technology, and motorized varifocal lens, this camera is ideal for both residential and professional security applications. The camera delivers crystal-clear images, both day and night, and makes it easy to remotely adjust the viewing angle.

Smart Dual Light technology combines infrared and warm-white LED lighting. Under normal conditions, the camera uses invisible infrared illumination. As soon as a person or vehicle is detected, the camera automatically switches to warm-white light for clear color images and a deterrent effect.

The motorized 2.7–13.5 mm varifocal lens allows you to precisely adjust the viewing angle without physically moving the camera. This makes the camera suitable for a wide range of applications, such as entrances, parking lots, commercial buildings, and residential properties.

With built-in WizSense AI technology, the camera distinguishes between people and vehicles and other movements. This significantly reduces the number of false alarms caused by, for example, animals, rain, or moving leaves. In addition, the camera supports intelligent features such as Tripwire and Intrusion Detection for even more reliable security.

The rugged metal housing with IP67 certification makes the camera resistant to dust, rain, and harsh weather conditions. Thanks to support for PoE (Power over Ethernet), only a single network cable is needed for both power and data, which keeps installation simple. Furthermore, the camera features a built-in microphone for audio recording.
