What is a GeoVision DVR Security camera? GeoVision is a manufacturer of Internet Protocol or IP security cameras. A DVR or Digital Video Recorder is a device similar to the hard disk drive on a personal computer, in this case used to store digital video files. A GeoVision DVR security camera is an IP digital video security camera that can either be connected to a personal computer using either a GeoVision DVR PC card or via the internet. Perhaps a little background information and a closer look at GeoVision products will help to describe this concept in detail.
