Dahua 4K 8MP IP Camera, WizSense, Smart Dual Light 60m, Microphone, Motorized Lens 2.7 mm13.5 mm, Face Detection IPC-HFW3849T-ZAS-IL-27135

The Dahua IPC-HFW3849T-ZAS-IL camera is a bullet-type model from the WizSense 3 series, designed for high-resolution surveillance with maximum installation flexibility. Equipped with a 1/2.7″ CMOS sensor and an 8 MP resolution (3840 × 2160), the camera delivers extremely clear and detailed images, suitable for scenarios where identifying people or vehicles at a distance is essential.

The motorized varifocal lens (2.7–13.5 mm, 5x optical zoom) allows remote adjustment of the field of view without physical intervention from the installer, significantly simplifying the setup process.

Smart Dual Light Technology

The Smart Dual Light technology integrates 4 multi-core illuminators (IR + warm light), each with an illumination range of up to 60 meters, and supports 3 configurable lighting modes. This allows the camera to provide full-color images when needed or automatically switch to IR mode for discreet surveillance.

The Xinghan Vision model brings significant improvements in target detection and image quality through advanced AI algorithms, complemented by AI SSA (Scene Self-Adaptation) technology, which automatically adjusts image parameters based on environmental conditions.

Smart Features

Intelligent functions include IVS with intrusion detection, tripwire, stay detection, and loitering detection, all with accurate human and vehicle classification. It also features SMD 4.0 and AcuPick for fast search in recordings.

The camera includes a built-in microphone and supports local storage on MicroSD cards up to 512 GB or NAS storage. Electronic Image Stabilization (EIS) and electronic defog enhance performance in demanding outdoor surveillance scenarios, while IP67 protection ensures reliable operation in harsh weather conditions.
