What is NVR?
NVR Full Form: The term NVR stands for Network Video Recorder. It is a system used for the recording of video data from IP cameras. Unlike its counterpart, the DVR (Digital Video Recorder), which works with analog cameras, NVR is designed specifically to handle video from digital IP cameras.
How Does NVR Work?
An NVR system captures video data and stores it on a hard drive, cloud storage, or other forms of digital storage. Since it operates over a network, it allows for greater flexibility in camera placement and scalability of the security system. The key advantage of an NVR over a traditional DVR system is its ability to provide higher video quality, easier installation, and better integration with modern IP camera technology.
