A US school district is giving its surveillance system an upgrade with the introduction of facial recognition.

The technology introduced in a New York state district means they will soon check each face against a database of expelled students, sex offenders and other possible trouble makers.

It could be the start of a trend as more schools wary of shootings consider the technology.

Just last week, a Seattle company began offering a free version of its facial recognition system to schools.

Discussion about Lockport's facial recognition plan has provoked a debate.

The New York Civil Liberties Union wants to keep the technology out of schools in Lockport and throughout New York, calling it invasive and inaccurate.
