Dahua Intrusion Analytics And VMD Tested (Poorly)

Author: IPVM Team, Published on May 21, 2018

Dahua ships basic analytics on practically all their cameras, ranging from low cost to high end. To see how these analytics work in real world scenes, we tested multiple cameras indoors and out, varying in resolution, field of view, and form factor:

  • Dahua N25BB5Z 1080p Bullet
  • Dahua N52BM3Z 5MP Dome
  • Dahua N84BG44 4K Dome

Inside, we examine:

  • False negatives
    False positives
  • False alerts - where and how many
  • Indoor performance
  • Outdoor performance
  • Detection range / PPF thresholds
  • Configuration recommendations
  • VMS integration

Readers should also see our recent tests of Axis VMD4 and Hikvision Camera Analytics.
