A digital video recorder (DVR) may be a device designed for recording video in a digital format within a mass storage device such as USB flash drive, hard disk drive or any other capacity device. With an analog camera, DVR supports features such as remote access movement detection, real-time playback, recording, and backup. Digital video recorders can record different videos from diverse channels at the same time. When it comes to the security surveillance system, the screen show signal goes directly into the DVR and is then converted into a digital format with the assistance of a MPEG-2 encoder. From there it is broadcasted to two unique targets, one to the hard drive for storage and the other to the screen display for seeing. Mivanta offers the most excellent DVR Camera.
