TVT / InVid Facial Recognition Tested

By: Rob Kilpatrick, Published on Mar 25, 2020

Facial recognition is frequently sold for thousands of dollars per channel but some China manufacturers are offering full facial recognition systems for under a thousand dollars.

But how well do such low-cost facial recognition systems work?

We bought TVT OEM InVid's facial recognition system to see where it worked and where it did not, including:

  • 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 proper recognition?
