The Network Video Recorder heralds the arrival of the next natural point in the development of recording technology. It is important to differentiate between DVRs and NVRs, as both are often termed 'digital' A DVR digitally compresses analog video feeds and stores them on a hard-drive,the term 'digital' referring to the compression and storage technology, not the transmitted video images. The DVR therefore has to be located near the analog feeds. In contrast an NVR stores digital images directly from the IPnetwork.
