National Taichung second senior high school has been seeking to upgrade its conventional DVR system to better protect its students and faculties. Prior to the upgrade, the school possessed an outdated surveillance camera system which sent video surveillance images to only one server in the security center. This had caused a lot problems to the school that if the server in the security center crashed, the entire saved data would be wipe out. There would be no back-up data to retrieve if there were disputes-between parents and teachers, vandalism, accidents, and even in helping police investigation.

Since the school had experienced the shortage of video surveillance capabilities, it developed requirements in selecting the replacement. First, the new system had to be cost-effective with as minimal of system replacements and training needs. Second, the DVR needed to be constant to prevent any data loss. Third, the video surveillance needed to be centralized into one central monitoring with back-up storage ability.

A total of 22 AVerDiGi EB1304NET SATA+ DVRs, along with CM3000 central monitoring system and NV7000 series capture cards were installed to connect existing cameras in those high-profile areas throughout the campus. They have provided the school with extra back-up video surveillance storage that when the main hard disks crashed, the school staffs would be able to retrieve the data locally.
