Magnetisches Aufzeichnungs/Wiedergabegerät

摘要

A video camera 201 is connected to a video signal amplifier 1 through a video signal input terminal 203, the video signal amplifier 1 is connected to the input side of an image memory 10 through an A/D converter 11 for converting video signals given in analog signals into image data which are digital signals and the image memory 10 is provided with semiconductor memory for storing video signals converted into digital signals. Thus, it becomes possible to continuously record images from before the opening of door until after the opening of the door and thus obtain a magnetic recording and playback apparatus of high monitoring effects. <IMAGE>
