Many educational facilities are improving their school parking lot safety by placing a wireless emergency call box in the parking lot that communicates with wireless base station intercoms or hand held two-way radios. These call boxes are placed at strategic points around the campus parking lots and they enable a student to call for assistance.

A wireless base station intercom is placed in a security guard station, plus security guards are given handheld two-way radios so they can still receive calls while they are roaming the campus.

These callboxes add an extra level of security in the event a student does not have a cell phone or their cell phone battery is dead.
