LOCKPORT, N.Y. — A New York school district has finished installing a facial recognition system intended to spot potentially dangerous intruders, but state officials concerned about privacy say they want to know more before the technology is put into use.

Education Department spokeswoman Emily DeSantis said Monday that department employees plan to meet with Lockport City School officials about the system being tested this week. Lockport is preparing to bring its system online as cities elsewhere are considering reining in the technology’s use.

The system is expected to be fully online on Sept. 1 and is designed to enable security officers to quickly respond to the appearance of expelled students, disgruntled employees, sex offenders or certain weapons the system is programmed to detect.

Only students seen as threats will be loaded into the database.
