Long Term Storage / Digital Tape (Soleratec)

Author: John Honovich, Published on Jun 26, 2011

Long term retention requirements and large camera counts can result in expensive storage systems. Users look to a variety of techniques and options for minimizing storage costs and size. In this note, we examine one approach - Soleratec's RSM offering combined with digital tape storage. We then contrast its strengths and weaknesses to network based storage and storage optimization techniques (such as frame pruning, transcoding, etc.).

First, Soleratec's general approach is uncommon for video surveillance so understanding the differences are important to start:
