| An NVR (Network Video Recorder) is an IP (Internet Protocol) based device that connects multiple IP cameras simultaneously via a centralized network recorder. The videos are stored in digital format on either a disk drive, SD memory card or other digital storage devices. NVR are managed remotely via LAN or over the internet, which gives greater management flexibility than conventional DVR solutions.
NVRs are similar to DVRs; however the two have distinct differences. NVRs allow you to view, control, and record video from all connected cameras via one centralized interface. The interface is Web based, enabling the use to view, manipulate and manage the video from any IP connected device, including desktops, tablets, mobile devices etc. The main difference between the two is that video on a DVR is encoded and processed at the DVR, whereas video on an NVR is encoded and processed at the camera, and streamed to the NVR for storage or remote viewing.
