Hikvision AI Problems Criticized By Chinese Publication

By: John Honovich, Published on Apr 09, 2019

Hikvision's facial recognition works poorly, causes delays and worsens learning, according to a new investigation by one of China's leading publications. Sixth Tone's Cameras Above The Classroom offers in-depth analysis of using AI, including facial recognition, to manage schools.

The reporter explains Hikvision's problems:

Everyone I talked to at Hangzhou No. 11 Middle School and Niulanshan First Secondary School expressed skepticism about the accuracy and reliability of facial recognition technology. As part of their smart campus initiative, Hangzhou No. 11 uses Hikvision’s facial recognition cameras to record the students’ attendance rate and for on-campus payments, but it doesn’t seem to work very well. A female student told me that Hikvision’s system is particularly inaccurate for girls. “Once we change our hairstyles or wear glasses, the camera won’t recognize [us] anymore,” she says through text. The different lighting and angles of their faces also slow down the recognition process, making the lines during lunch extremely long. [Emphasis Added]

While nearly every manufacturer, including Hikvision, makes sweeping claims about their facial recognition working with glasses, mask, hair changes, etc., what the reporter found is unsurprising to those that understand how the technology works. It works sometimes, maybe even most of the time, but the exceptions cause significant operational problems.
