What role does a network video recorder (NVR) play?

A network video recorder (NVR) is primarily designed to capture, record, and store video footage from network-based IP cameras. Its main function is to process the video streams transmitted over the network, allowing for centralized management of video data. Unlike traditional analog systems that rely on digital video recorders (DVRs), NVRs are built to handle the digital video output from IP cameras, which provides advantages such as better image quality, scalability, and remote accessibility.

NVRs also often come with additional features, such as motion detection, scheduling, and playback options, but their core responsibility remains focused on recording and storing the video footage. This functionality is essential for security applications, surveillance management, and ensuring that video evidence is readily available when needed.
