Columbine is a school that is in a higher socio-economic level so its philosophy as a suburban high school is probably different than what you would find in an urban high school. Historically, in our county, there have been a lot of keys available for teachers and staff to have the right to come and go at all hours and on weekends. Since Columbine happened, especially at that high school, we started restricting access into the buildings. We have restricted access to the building, reducing to five the number of locations people can enter the school. We have probably 30 to 40 doors overall.
Doors are still available for exiting but anyplace that people enter is a controlled point.
All of those access points are monitored by camera. From a security location we can watch who is coming and who is going. They go through a multiplexer and they are stored and kept for 30 days. They are on video right now. The system has the capability of going to other types of systems because it is all-digital.
