Digital Video Recorder (DVR) is technology that takes all the great features of a VCR and places it in the digital age. Like a VCR, common use of a DVR is for recording TV shows or recording your kids playing football. Once you have a VCR or DVR you can record your favorite TV shows or your kid’s activity now and watch them whenever you want. With a DVR, you no longer record on a number of tapes, but on a hard disk instead. Some systems even let you transfer the content to a DVD or your laptop.
DVR system uses the same camera and structures for cabling as the
older CCTV analog systems, but the old VCRs have been replaced with DVR for
storage of the data. The data is converted to digital so that it can be stored
on hard disks, but the quality of the images captured remains analog since this
is how it originated. But current technology, you can find a digital camera and add it to the DVR, so the image is already in digital format from the time you do the recording.
With addition of a camera, a DVR can be used for home surveillance; in addition to the ability to record your favorite shows whenever you want to, DVR surveillance camera is a system that combines a DVR with a surveillance camera. Originally video surveillance was based on analog technology, i.e. closed circuit television (CCTV) and recording on video tapes.
The advantages of DVR surveillance camera are image quality, which is much clearer than a VCR; storage facility which much bigger than a tape; the ability to search for an event without need to rewind the tape.
