Dahua 5MP Starlight Camera Tested (N52BM3Z)

By: John Scanlan, Published on Jan 30, 2018

Is 5MP the new 1080p? According to our recent statistics, average resolution continues to trend upwards. And now, manufacturers releasing new generation 5MP cameras featuring super low light capabilities previously found in 1080p models.

In our first test of this new generation of 5MP models, we look at the Dahua 5MP starlight N52BM3Z dome, examining:

  • Physical features
  • Installation issues
  • IR coverage
  • IR range
  • Low light image quality
  • Full light image quality
  • WDR performance
  • Bandwidth
  • VMS support

Note: This report is the first in our tests of new generation 5MP/6MP cameras, with upcoming reports on the Axis Q3517-LVE, Hanwha XNV-8080R, and Hikvision DS-2CD4565-IZH, as well.
