A network video recorder is similar to a digital video recorder. It is comprised of both a computer as well special video management software and does not have a dedicated keyboard or monitor. The basic function of the network video recorder is to ensure remote access to a live video stream from the Internet Protocol camera along with simultaneous recording. It is a true digital system and records the digital images or videos received over the network onto to a hard disk or other storage device. A network video recorder usually has a user friendly graphical user interface, flexible recording, playback capability, intelligent motion detection and pan-tilt-zoom camera control capability. They usually support Windows or Linux environments.
One advantage of a network video recorder is the relative ease in installation and usage. Another feature is the capability of handling great amounts of video streams for both recording and rebroadcasting. The unit can be placed anywhere and is not limited to a nearby area, unlike a digital video recorder.
However, compared to a PC server platform, it is less scalable as it is designed for optimal performance against a specific number of cameras.
A network video recorder supports a wide range of software applications and optional video analytics.
