DVR

A Digital Video Recorder (DVR) that takes analog video signals from security cameras and converts the video stream into a digital format for storage on an internal hard drive. A DVR also provides a user interface for managing the stored video files and often features for setting motion detection and controling PTZ security cameras.

In selecting a digital video recorder (dvr), a DVR often provides a method of accessing the system remotely over the Internet in addition to the management interface accessed directly on the system.

The term DVR is also used in consomer electronics for a device that can record, pause, and playback television.
