What is a Digital Video Recorder? (DVR)
A Digital Video Recorder (DVR) monitors and records the video output (or what is being captured) of the CCTV cameras in operation. The video is then recorded to a hard disk (HDD) integrated inside the Digital Video Recorder (DVR) and they can be displayed on a monitor or TV screen. Some DVRs can also be connected to the internet, these are called Internet Protocol DVRs (IP). These allow you to monitor an area via a Local Area Network (LAN) or from a remote location over the internet, meaning you do not need to be in the same place as the DVR or CCTV System
