High schools in the US can sometimes get very close. There are often large schools of two to three thousand students and in a country with ample access to weapons, security becomes an issue very quickly. Both university level and lower education levels in the US will probably have large security camera systems. I know some smaller schools can't quite afford it but the medium and large state schools can.
