HDW3849T-ZS-IL, 8MP Smart Dual Light, Wizsense, 2.7-13.5mm Black

Dahua Smart Dual Light uses smart algorithms for accurate target recognition. In night conditions, IR illumination is active by default. When a person or vehicle is detected, the camera automatically switches to warm light for full-color imaging. Once the target leaves the monitored area, the camera switches back to IR illumination, minimizing light pollution.

• Sensor & Resolution
  1/2.7″ CMOS sensor with 8 MP (3840×2160) video at up to 30 fps

• Illumination & Night Vision
  Multi-core light sources with automatic switching between infrared (IR - up to 50 m) and warm (color) light (up to 40 m) for clear images even in darkness

• Lens & Viewing Angle
  Motorized vari-focal lens from 2.7 - 13.5 mm, with a wide range of viewing angles: horizontal 114°-32°, vertical 58°-17° and diagonal 138°-36°
