The Groton school district is installing security measures, allowing staff to lock gymnasiums, libraries, auditoriums and cafeterias.
The Day of New London reports that the $110,000 project will install locks for teachers to use during emergencies to secure areas from inside, without stepping into a hallway.
Initial upgrades included a front door entry system. A lock, camera and buzzer system was installed, allowing the secretary in the main office to see who was at the door, confirm an appointment and open the door remotely.
Groton also installed "panic buttons" in schools that automatically dial 911, cameras that record activity in playgrounds and other areas, and card readers that allow only authorized personnel with issued cards to move between main buildings and portable classrooms.
