Abstract: Mobile Digital Video Recorders (MDVR) for security applications can require extensive storage requirements as video quality, video resolution, and camera counts increase. Frequently, the storage requirements over many days or weeks exceed the capacity of any one storage device leading to the use of multiple storage devices. However, ruggedized storage devices that are usable within a moving vehicle platform are expensive and have lower capacity capabilities per unit, and thus place a limit upon the storage that may be used within any single vehicle. This invention employs a mixed configuration of rugged and non-rugged storage devices in combination with robust control software modules to achieve the total on-board storage requirements of the system economically and without requiring special accommodation within a vehicle for a high number of storage devices.
