One California city discovered Flock’s license plate cameras have been unsuitable 71% of the time

In short: The controversy surrounding Flock cameras primarily facilities on privateness and fears of a surveillance state. Nevertheless, the cloud-based license-plate-reading system’s accuracy and effectiveness have additionally drawn scrutiny. In a single notably egregious case, an inner assessment uncovered greater than 1,000 false positives over two years.

Police in Roseville, California, discovered that, out of 1,427 incidents during which the city’s AI-powered license-plate cameras flagged a car as stolen or utilized in a felony, the cameras misinterpret the plate in 71% of instances.

Flock, the startup that provides the cameras to Roseville and roughly 6,000 different communities throughout the US, attributed the errors to Roseville’s atypical digicam setup, however as Enterprise Insider reviews, the outcomes might expose flaws in an already controversial know-how.

Flock’s cameras, sometimes positioned on site visitors mild poles and roadsides, {photograph} passing autos and analyze their traits, together with license plates, colour, make, mannequin, and different particulars through machine studying. Authorities can search the corporate’s cloud database for autos utilizing descriptions to trace their actions, which they are saying has helped clear up crimes and discover lacking individuals.
