Dahua 4K Micro 4/3 Camera Tested (IPC-HF8835F)

Author: John Scanlan, Published on Apr 03, 2018

Dahua is going big.

Their new 4K HF8835F Micro Four Thirds sensor is one of the largest now on the market. Dahua is claming:

Starlight Technology and Ultra Wide Dynamic Range to produce crisp, clear images with minimal ambient light

How well will Dahua face in this segment against Axis' Q1659 or Sony's 35mm VB770? And how does it compare to 1/2" super low light models like Hanwa's ExtraLux or Hikvision Darkfighter?

We bought and tested the HF8835F to find out. Inside we report our findings on:

  • Dark (<0.1lx) monochrome image quality
  • Low light (<1lx) color image quality
  • Daytime image quality
  • WDR performance
  • Lens options
  • Physical features
  • VMS support
  • Bandwidth
