Computer or appliance?

Is a DVR a computer or an appliance? If the DVR software and cards reside in a Windows PC, it seems like a simple answer. But what about those little black boxes we're finding more often now?

The typical digital video recorder (DVR; or networked video recorder, NVR) includes a host application (usually a license-free Linux OS), video conversion software, storage and disc management application, and a VMS interface to manage the integrated video. The embedded video surveillance application and OS provide an appliance rather than a computer, streamlining the process of integration, maintenance, and support. As such, the DVR is the appliance that replaced the analog videocassette recorder (VCR).

So, when your computer crimes investigators don't know what to do with your DVR, fret not - after all, it's an appliance and not a DVR.
