Hikvision Dual Lens Face Recognition Camera Tested

By: Rob Kilpatrick, Published on Nov 19, 2019

Hikvision's Dual Lens Facial Recognition camera, claims that it "adopts advanced deep learning algorithm and powerful GPU to realize instant face detection, capture, and comparison to accomplish face recognition and related alarm triggering."

We bought and tested the iDS-2CD8426G0F-I, examining:

  • Does it miss people walking through the scene?
  • Does it misidentify people?
  • Does confidence drop in different scenarios?
  • Does it recognize inanimate objects as faces?
  • What PPF is required for optimal performance?
