BriefCam Video Analytics Tested

By: Ethan Ace and Rob Kilpatrick, Published on Jan 06, 2020

BriefCam, acquired by Canon in 2018, is one of the most commonly used video analytics offerings in the West. But how well does it work?

We tested BriefCam for over the past month to see how it performed, examining:

  • How does BriefCam search compare to typical VMS search?
  • How well does clothing style and color analysis work?
  • Does it accurately classify age and gender?
  • How well does facial recognition work?
  • Are vehicles accurately classified and searched?
  • How well does mobile app search work?
  • How does it compare to competitors such as Avigilon and Anyvision?
