Dahua IPC-HFW3841T-ZAS-S2, 8MP 4K, WizSense AI bullet camera with 2.7–13.5 mm motorized zoom

The Dahua IPC-HFW3841T-ZAS-S2 is a professional 8MP IP security camera that combines high-quality imagery with intelligent AI detection. Thanks to its 4K Ultra HD resolution of 3840 × 2160 pixels, this bullet camera captures highly detailed images. This makes it ideal for securing commercial properties, retail stores, parking lots, and residential homes.

The camera features a motorized varifocal lens ranging from 2.7 to 13.5 mm. This allows you to remotely adjust the field of view, from a wide-angle overview to a zoomed-in view of specific areas. The integrated infrared illumination provides night vision up to 60 meters, enabling surveillance even in complete darkness.

With Dahua WizSense technology, the camera can intelligently distinguish between people and vehicles. Features such as perimeter security, line-crossing detection, and intrusion detection help identify unwanted events more accurately and reduce unnecessary alerts.

The built-in microphone enables audio recording. Additionally, the camera supports a microSD card up to 256 GB for local storage. Thanks to Power over Ethernet (PoE), both power and the network connection are provided via a single network cable. The rugged housing with an IP67 rating makes the camera suitable for outdoor use in a variety of weather conditions.
