Advanced Surveillance at Parkland

Accuracy and invasiveness are being questioned.  Back to the transparency of algorithms involved.

Florida's Broward County Public School system will deploy an experimental artificial intelligence network to monitor students and flag potential threats. The Avigilon installation from Motorola Solutions combines 145 surveillance cameras and software so security officials can track students based on their appearance, and it can automatically alert a school-monitoring officer when it senses events "that seem out of the ordinary" and people "in places they are not supposed to be." The deployment has raised concerns from students, parents, and educators about Avigilon's accuracy, invasiveness, and efficacy. Particularly disconcerting is the fact that the public has received no clarification on how the network's algorithms operate, while technology and civil liberties experts cite the camera software's unproven track record for preventing school violence. Motorola Solutions' Mahesh Saptharishi said the accuracy rate of Avigilon's "appearance search" feature varies widely, depending on variables such as lighting and time of year.  ... "
