Dahua DB41AW – Wi-Fi 6 Video Doorbell 4MP, 2K, AI Detection, IR Night Vision

The Dahua DH-DB41AW is a smart Wi-Fi video doorbell from the Dahua Wireless Series, designed to secure entrances of residential and small commercial properties. Its 4MP sensor paired with an ultra-wide fisheye lens delivers sharp 2K imagery (2560×1440) and covers a significantly wider field of view than conventional fixed-lens doorbells. On-device AI distinguishes between humans and vehicles in real time, while IR LED illumination provides clear night vision up to 10 m. The doorbell connects wirelessly via Wi-Fi 6 (2.4 GHz) and can be quickly set up via Bluetooth pairing. Remote management is handled through the Dahua DMSS mobile application (iOS and Android).
