An image acquisition system includes an image acquisition device and a commanding device configured as a member separate from an image acquisition device proper to transmit a command for controlling the image acquisition device to the image acquisition device proper. The image acquisition device includes an authentication command receiving unit which receives an authentication command transmitted from the commanding device and containing authentication information used by the image acquisition device to authenticate the commanding device, a general command receiving unit, arranged separately from the authentication command receiving unit, which receives a general command transmitted from the commanding device and not containing the authentication information, an authentication command recognition unit which recognizes the authentication command received by the authentication command receiving unit, and a function limiting unit which limits a function of the image acquisition device based on the authentication command recognized by the authentication command recognition unit.
