Are storage technologies for video surveillance up to the task of meeting consumer demand? End users seeking high quality video footage while also looking to reduce costs may discover that finding an affordable, scalable storage solution can be challenging.

The transition from analog to digital has greatly impacted storage solutions. Higher quality footage means a clearer picture, but also greater bandwidth, and thus more storage capacity. The storage capacity required by IP network and megapixel cameras can be colossal. IT professionals in charge of managing video data storage may be overwhelmed by its demands.

There are several storage technologies available for archiving video data: hard disk drives (HDD), multiple disk solutions (RAID), storage area network (SAN), directly attached storage (DAS), or network attached storage (NAS). DAS is a single-server storage device, while SAN is a local network.  Video management software communicates between the storage technology and surveillance application. Cloud services also offer digital storage solutions online.

Ultimately, organizations can conserve costs by consolidating servers and investing in cameras that reduce bandwidth, optimize data retention and capture motion only when detected. The goal in video surveillance storage is the less storage the better; the less data that needs to be transmitted, stored, and retained, the more that costs can be reduced.
