Dahua 4K Turret Tested Vs Hikvision (N84BG44 )

Author: John Scanlan, Published on Aug 02, 2017

Dahua has released their latest low cost 4K model, the N84BG44, claiming Smart H.265+ and 50m IR range. We bought and tested this new model against Hikvision's recent low cost 4K camera to see how it compares in:

  • Full light scenes
  • IR range and coverage
  • Wide dynamic range
  • Bandwidth
  • Installation

And more. See our full results inside.

Note: Dahua was one of the first manufacturers to release a low cost 4K model, tested by IPVM in 2015. However, that model has since been discontinued and superseded by this new generation.
