A digital video recorder is a device that allows video images to be stored on a video disk. This means no more tapes. Because of digital technology, using a digital video recorder makes navigation through video playback much faster and easier.

One advantage of a digital video recorder over a VCR is that playbeack will never be degraded over time. Picture quality with the use of a digital video recorder is higher due to higher resolution than analogue recorders. A digital video recorder footage is more likely to match the resolution quality of the high resolution professional cctv camera.

Digital video recorders use MPEG or JPEG file formats. JPEG recording replaces an image everytime with a new image while MPEG replaces only what has changed since the last image recorded. A digital video recorder using MPEG is far better as file sizes are smaller allowing more activity to be recorded. A digital video recorder can usually be connected so there is internet access.
