NVRverkkojärjestelmä

NVRverkkojärjestelmä, often abbreviated as NVR, refers to a network video recorder system. This technology is primarily used for recording and managing video feeds from digital surveillance cameras over a network. Unlike traditional DVR (Digital Video Recorder) systems that require a direct connection between cameras and the recorder, NVRs utilize IP (Internet Protocol) cameras that transmit video data across a local area network (LAN) or a wide area network (WAN).

The core function of an NVR is to receive, store, and playback video footage from connected IP cameras. It acts as a central hub, allowing users to monitor live feeds, search for recorded events, and export video clips. NVRs typically offer various storage capacities, allowing for extended recording periods depending on the number of cameras and the desired video quality. They also provide features such as motion detection recording, remote access via mobile devices or computers, and advanced search functionalities.

NVRverkkojärjestelmä systems are commonly deployed in a wide range of applications, including residential security, commercial surveillance, public safety, and industrial monitoring. Their network-based architecture offers greater flexibility in camera placement and scalability compared to DVR systems. The use of IP cameras also allows for higher resolution video and additional intelligent features such as video analytics.
