What is a NVR Unit
NYR stands for Network Video Recording. A unit will vary in cost but can be anywhere from R7000 upwards. The NVR unit software records the video and converts this into digital format to transfer to a disk drive, USB or memory card. The stored content is usable in court for supporting our case. The NVR records IP cameras and the information is transmitted via a network cable. DVR's record analog or coax based cameas.
An IP camera is an Internet Protocol camera, a digital camera used often for suveillance. CCTV cameras are analog, and can send data via a network or the internet. An NVR converts the analog content to digital content.
