Digital video recorders configured for physical security applications record video signals from television cameras for detection and documentation purposes. Many can record audio. But they have evolved into devices that are feature-rich and supply services. They exceed the straightforward recording of video images. VCRs did this previously.

A digital video recording system works with a set of CCTV cameras that are connected to a Video recorder. This device can record digital videos. You may have an analog CCTV system. But you can easily transform it into a digital system by replacing the VCR with a DVR.
