From the console, administrators can view live images from surveillance cameras, control pan-tilt-zoom cameras or search for video clips stored on digital video recorders (DVR). When an event or alarm is triggered, the system can tell the DVR to begin recording, display live video from a linked camera at the location, map the alarm location and send an e-mail to an administrator.
A school's security system should be as flexible as possible, taking advantage of what a school already has, while being capable of integrating future technologies and tools as they are introduced.

Tying multiple properties together
The University of Medicine and Dentistry of New Jersey serves as the state's university of health sciences and is the largest such institution in the nation. On any given day, the university's network of five schools spreads across five cities and serves up to 18,000 students, researchers, teachers, patients and employees.
When the university sought to improve security on its campuses, it looked for a single system that could tie all of its properties together. Its aim was to make the facilities highly accessible and highly secure.
The university's security system has evolved from a $100,000 investment in 1993 to more than $2 million today. Each step of the way, the university considered its ultimate goal of tying all security systems together.
"This is a very complex system with dual credential-based access control with 22,000 users, including multiple-level access at certain points," says Sgt. Frank DeMarzo, supervisor in charge of communications for the public safety and police departments on the main Newark campus. "Currently, the predominant card reader is a magnetic-stripe reader, but we are migrating to dual credential readers that also accept proximity cards throughout our campuses."
The university recently upgraded its CCTV system to digital video multiplexer-recorders with Ethernet capability and plans to add 75 cameras. Security staff can record, play and view surveillance activity simultaneously with digital day/night pan-tilt-zoom cameras stationed throughout the five campuses.
Integrated surveillance and access-control systems allow officials to call up instant live video, and recordings of alarm conditions and system activity.
A security boost
DeKalb County (Ga.) Schools upgraded its video-surveillance systems by installing 3,500 surveillance cameras and 220 digital video multiplexer recorders with Ethernet-connection capabilities at 140 district facilities. The security system has helped resolve incidents more quickly and accurately, and has reduced the need for guard service at district schools.
The school district wanted to eliminate videotapes and have a way to view camera feeds over their LAN (local area network). Now, each school has its own control room, and school detectives can review video quickly and burn evidence CDs if necessary.
Each control room has a 21-inch monitor and a 17.4-inch plasma screen. The plasma screen doubles as a CPU monitor for review and access control.
Every school in the district has 32 to 48 cameras. Most are situated in public areas such as hallways, parking lots, cafeterias and school entrances. The cameras are integrated with the school's access-control system.
The cameras also help to deter student violence. Fights and break-ins have been recorded in schools, and the word quickly got out that school officials had videotaped evidence. The district also has used video evidence to help track down an arsonist in a neighborhood near a school.
