first discovered shortly after charlie ginsburg invented the first video recorder for ampex in 1956, video feedback was considered a nuisance and unwanted noise. technicians and studio camera people were chastised for allowing a video camera to see its own monitor as the overload of self-amplified video signal wreaked havoc with the 1950s video pickup, often ruining the pickup. it could also cause screen burn-in on a playback tv and/or monitors of the time as well, by generating static brightly illuminated display patterns.

a network video recorder (nvr) is a specialized computer system that includes a software program that records video in a digital format to a disk drive, usb flash drive, sd memory card or other mass storage device. an nvr contains no dedicated video capture hardware. however, the software is typically run on a dedicated device, usually with an embedded operating system. alternatively, to help support increased functionality and serviceability, standard operating systems are used with standard processors and video management software. an nvr is typically deployed in an ip video surveillance system.
