The continual news stories of security breaches and shootings occurring on campuses have led school districts across the United States to review their security systems. When Montgomery County Public Schools (MCPS), the largest school system in Maryland, reexamined their technology, they realized there was a need to increase security around the perimeter of more than 120 elementary schools. MCPS sought a solution that would lock doors, establish regulated access for visitors, and give staff the ability to monitor and grant access to guests.
