Dahua 4K Turret Tested Vs Hikvision (N84BG44 )

By: 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 However, that model has since been discontinued and superseded by this new generation.

Maybe I missed it but I didn't see any mention of the built in mic? I was curious to see how you rated the quality of the audio and if it works with any of the VMSes. We have only installed them with Dahua NVRs and have little experience with other audio surveillance (except for a single omni directional Louroe mic we did a few years back) for comparison.

I have hear the mic on a 4MP camera on a 4K TV, it sounded very good...also when played back through the NVR audio was clear if this helps

Smart H.265+ bitrates were lower than Smart H.264+ in all scenes tested, by nearly 70% in daytime scenes, and ~40% in low light.

H.265 finally delivering > 50% savings over H.264?

50% is not totally uncommon. Hikvision's H.265+ was reached 50% in some cases, as well. 

I wouldn't make a blanket statement that it's always 50% lower than H.264, but it's possibly that low in some scenes.

Our experience has been that the 8mp turrets were coming in consistently between 40-60% lower bandwidth usage on h265 than the 4mp models on h264
