One very outstanding feature of digital cameras is the fact that their data is compressible and could be transferred at very high speeds, much faster than the time it would take to play back the video, without any loss in quality. This simply cannot be easily done with analog technology, and this was slower in each case. Progressive data loss was also a fact of life, and still is for many people who have not yet chosen to make the switch to digital video recorder technology. Digital video recorder has all but completely swept the field.
