The K-12 market represents a wide range of education facilities that includes public and private elementary, secondary, and high schools. Security risk tends to be more prevalent at the high schools, but some middle and elementary schools also require security systems. In the high schools in particular, there might be a higher level of implementation of security systems in urban areas as compared to suburban and rural areas.

The main risk that is addressed in the K-12 market is intrusion. These schools rely on video and electronic access control systems focused on entryways, hallways and the cafeteria. As the grade level increases, so does the number of cameras used. This is influenced not only by the school size (elementary schools are typically smaller than middle schools; middle schools are typically smaller than high schools), but also by the increased risk of vandalism and deviant behavior as children grow towards adulthood.
