Network video recorder (NVR) is advanced video recorder which is designed to record compressed video footage to hard disk drivers (HDD). The NVR can receive the video/images or even audio through an Ethernet network (cat5/cat6) from IP cameras. Typically, NVR can support high definition recording including 1280x720 (720P) and 1920x1080 (1080P), some advanced NVRs with capability to record 3 megapixel and 5 megapixel resolutions for ultra HD video surveillance applications. Therefore, when compared to a DVR and analogue cameras system, an NVR and IP cameras is more expensive, however, it provides much higher resolution and superior image qualities.
