There are three market segments in which digital video technology functions as part of a business solution. These include DVRs, non-integrated digital video management systems (DVMSs) and DVMSs as a seamlessly integrated part of a total security solution.
The most rudimentary of these is a stand-alone DVR. These devices are typically low cost replacements for analog video cassette recorders. Because of high demand and a proliferation of such hardware, DVRs have become price-based commodity items. They have limited functionality and operate independently of other systems, making them less effective in serving the more complex security needs of today's businesses.
