But we want to work harder at making it less of a chance. Crisis management and evacuation plans also have been designed for each school. Though the schools have experienced little violence, officials believe the cameras serve as a deterrent. Now that the students know we are taping them and that they're not fake cameras, I think they will respect them more. LHS has one monitoring screen that shows all the cameras' images simultaneously.
Officials also can zoom to one part of the building.
Liberty's administrators also re-keyed all the locks and revamped the phone system after bomb threats closed the school repeatedly last spring. The LHS switchboard, equipped with Caller ID, has new recording capabilities. The new system makes it very easy to trace a call and to retain a recording of the caller's voice. Fred Pfeiff said of the bomb threat callers. The school board has been very generous.
