Dahua 4Megapixel WDR IR Vari-focal Dome Network Camera IPC-HDBW2421R-ZS/VFS

The Dahua 4Megapixel IR Vari-focal Dome camera delivers 4MP resolution with a motorized 2.7mm – 12mm varifocal lens. The camera has an elegant blend of aesthetics combined with a range of easy mounting solutions, provides an excellent choice for a variety of small to mid-size applications at an affordable price.

True Day/Night

A day/night mechanical IR cut filter makes this camera ideal for applications with fluctuating lighting conditions. Delivering color images during the day and automatically switching to monochrome as the scene darkens.

Regions of interest

User defined feature that allows the operator to monitor specific areas of a scene while still maintaining overall situational awareness of less important areas.

Smart IR

Smart IR technology adjusts to the intensity of camera’s infrared LEDs to compensate for the distance of an object.This technology prevents IR LEDS from whiting out images as they come closer to the camera. The camera’s integrated infrared illumination provides high performance in extreme low-light environments up to 30m (98ft).

Wide Dynamic Range

Embedded with industry leading wide dynamic range (WDR) technology, vivid pictures are achieved even in the most intense contrast lighting conditions. For applications with both bright and low lighting conditions that change quickly, True WDR (120dB) optimizes both the bright and dark areas of a scene at the same time to provide usable video.


Supporting ±30% input voltage tolerance, this camera suits even the most unstable conditions for outdoor applications.


The camera conforms to the ONVIF (Open Network Video Interface Forum) specifications, ensuring interoperability between different network video products.

Smart H.265+

Smart H.265+ is the optimized implementation of H.265 and it deliver high quality video without straining the network. Technology includes a scene adaptive encoding strategy, dynamic GOP, dynamic ROI, flexible multi-frame reference structure and intelligent noise reduction.
