Dahua Analytics+ Tested

By: Ethan Ace and Rob Kilpatrick, Published on Aug 07, 2019

Dahua's analytics have performed poorly in past shootouts. But now, they claim their new Analytics+ "algorithms significantly improve accuracy and reliability."

To see how these new analytics perform, we bought and tested the N45DL7Z 4MP dome, examining:

  • How well does it perform vs. outdoor false alert sources such as rain, animals, and foliage?
  • How well does it perform vs. indoor false alert sources such as shadows, lights, and flashes?
  • Are human and vehicle classification accurate?
  • What distance/PPF level is required for detection?
  • How well does it compare to Avigilon, Bosch and Hikvision analytics?
  • How well does it compare to Wyze analytics?
  • What chips / AI are the analytics using?
