NVR(Network Video Recorder)

NVR stands for Network Video Recorder, which is a type of video recording device used in security camera systems. Unlike traditional DVRs (Digital Video Recorders), which record and store video footage locally on a hard drive, an NVR uses a network connection to store video footage on a remote server or a cloud-based storage system. An NVR typically consists of a computer or server, specialized video recording software, and a network interface card that connects the device to the network. The NVR is usually connected to the cameras in the security system via Ethernet cables, which transmit video data to the NVR for storage and management. One of the advantages of using an NVR over a DVR is that an NVR can support higher resolution cameras and can handle larger amounts of video data. NVRs also offer more advanced features, such as remote viewing, motion detection, and video analytics. Overall, an NVR is a powerful tool for managing and recording video footage in a security camera system, and it is widely used in commercial, industrial, and residential settings.
