(Digital Video Recorder) A security system device that records the video from up to 16 surveillance cameras on a hard disk. The frame rate can be switched from real time to time lapse in order to save disk space. Digital recorders are more flexible than earlier analog VHS tape systems, and the video can be easily transmitted over a computer network. A digital video recorder (DVR) is an electronic device that records video in a digital format to a disk drive, USB flash drive, SD memory card, SSD or other local or networked mass storage device.
