A Digital Video Recorder (DVR) records video to local storage devices, most commonly a hard drive. DVR General can record analog video sources on-site or capture video from a digital source. DVRs can be connected to analog cameras via coaxial cables, enabling them to be accessed remotely. DVRs offer enhanced functionality like the ability to search recordings for events, or sort by time and date. DVRs can be configured to automatically replace older footage once storage becomes full.
