In this video, I explain how a (DVR) Digital Video Recorder for CCTV works

DVR stands for Digital Video Recorder. It's a device that converts the analog signals from a CCTV camera to digital format, store the information into a hard drive and also send live video stream to other devices on the network.

A CCTV system that has a DVR is not totally analog. The cameras send video signals in analog format and the DVR converts these signals to the digital format before recording and sending over the network.
