Dallastown Area School District
Dallastown Area School District is located in York County, 34 miles south of Harrisburg, in the south central part of the Commonwealth of Pennsylvania. The district serves nearly 6,000 students in five kindergarten through fifth grade elementary schools, a sixth to eighth grade middle school, and a grade nine through twelve high school. The district employs 417 instructional staff, 277 support staff and 30 administrators.
The school district's IT department sought a flexible IP video surveillance system that would allow administrative staff and the school's resource officer to easily search and playback recorded video to determine the events surrounding incidents at the schools. Secretaries also needed to view video of the entranceways from their desks, in order to see a person requesting access to the school before unlocking the doors.
Nearly 120 FLEXIDOME IP cameras monitor the hallways and cafeterias in the district's high school and middle school. Day/Night cameras provide an extended dynamic range and mechanically switching IR filter to capture video in areas that have low light or that are near windows with excessive light.
For recording video, the cameras stream signals across the district's separate security IP network for storage on five RAID arrays
For recording video, the cameras stream signals across the district's separate security IP network for storage on five RAID arrays. Video Recording Manager (VRM) creates a virtual pool of storage using all of the RAID arrays, divides the total capacity into one gigabyte blocks and allocates storage for video recording to each of the IP cameras as needed.
With cameras that stream directly to RAID arrays, the district avoids using NVRs, which would have required extra time and funds to support. The district's streamlined system design and use of VRM software made installation easier. For example, recording settings were programmed in less than a day, compared to the five days needed for an NVR-based system.
The system design is extremely flexible, allowing the IT department to adjust frame rates of cameras in important locations without stopping the system from recording, reallocating storage disk space or reformatting the storage.
The school district reports that the system helps administrators more quickly identify which students were involved in incidents that happen in the schools. The students are more likely to be truthful about the role they played, when they see themselves on recorded video.In addition to the cameras already installed, the district's IT department plans to install AutoDome IP cameras around the exterior of the school buildings and in and around the five elementary schools in the district to help protect the younger students from external threats.
