Apples vs Oranges. Every 50 - 60 minutes every high school student is supposed to be in a particular room. You can bet the school cop and the APs have a “hot list” of the thugs. If they are wandering they can be located, as well as any potential victims. For instance: Thuggo isn’t in class but in a stairwell along with three other kids. Instant alert to trouble. One AP heads to each exit from the stairs, grabs them as they come out and deals with it / all APs converge and intercept. As to the “false sense of security”: every system is flawed.
An assault can happen within 30 seconds with serious injuries. Rape within 2 minutes. You are the one that brought up the security angle. Unless these alarms/chips can be self-activated they are nearly worthless as an acute security measure.
