A Digital Video Recorder (DVR) is a high-quality compact recorder that combines the functions of a recorder and multiplexer into one unit. Having no tapes to maintain, replace, or rewind means that this recorder can be set up once and virtually forgotten about unless a review of the video becomes necessary. It also dramatically reduces the down time for maintenance or repair that is generally associated with VCRs. DVR's can even give you the capability of logging into you camera system from anywhere in the world via the internet.
