A Network Video Recorder (NVR) is a device used for recording video footage from IP cameras over a network. Unlike traditional video recorders, NVRs store video data digitally, allowing for easier access and management. They are commonly used in security systems to monitor and record activities in various locations. NVRs typically offer features such as remote viewing, playback, and motion detection. They can be integrated with other security components, such as alarm systems and access control, to enhance overall safety. This technology is widely utilized in both residential and commercial settings for effective surveillance.
