Hikvision NVR
NVR (network video recorders) connect with CCTV security systems, enabling you to record what the CCTV cameras see, so it can be played back at a later date.
The NVR stores digital video streams from network cameras, and will normally incorporate a large-volume hard disk to allow for a long period of recording. NVRs differ from DVRs in its network connectivity, which allows digital data to be transmitted to other networked devices over the internet. Most NVRs can be directly connected to a network camera while a DVR is usually be connected to an analog camera.
