PURPOSE: An image storing device for CCTV is provided to reduce power consumption and to easily search for stored image data while reducing operation error ratio. CONSTITUTION: An image input terminal(13) is connected to an image output terminal through a cable(4) by making an image signal that is photographed by a CCTV as data. An encoding unit(14) includes a video encoder which encodes an image signal received through the image input terminal. A main body(10) includes a memory stick interface(15) connected to the encoding unit. A memory stick stores data which is outputted through the memory stick interface.
