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?
