Digital Video Recorders are the equivalent of older multiplexers and video cassette recording systems for surveillance requirements.

However, despite their name, DVRs are used for recording analogue video images and are unsuitable for digital IP camera networks and therefore suffer from the disadvantages of analogue recording environments.
