After the most recent school shooting in Parkland, Florida, schools across the U.S. are installing police-grade surveillance “gunshot-detection systems,” metal detectors and even biometric locks requiring facial recognition or a person’s iris, The Atlantic reported.
Hermosa Elementary in Artesia, New Mexico, has installed a network of wireless microphones that can analyze the audio signature of gunfire.
The devices are placed high on the ceiling in classrooms and hallways to alert authorities of the sound and location of gunshots. They can then identify the make and model of the gun/guns, and automatically seamlessly lock doors and set off alarms throughout the school grounds.
