a cam plate disposed inside the housing and fixed to the base part; a link including a first end moving along a guide part of the cam plate and a second end to rotate the camera when the housing rotates; a driving part for applying a driving force to rotate the housing; and a control part to determine a folded state of the housing by controlling the driving force applied from the driving part based on a vehicle speed, and to rotate the camera simultaneously with the housing based on the folded state of the housing so as to maintain a previously set angle of a camera view. ## Claims ### Claim 1 A camera monitoring system, comprising: a housing configured to rotate around a coupling shaft of a base part disposed in a vehicle; a camera disposed on one end of the housing; a rotating hinge part configured at a position facing the housing on the base part; a cam plate disposed inside the housing, and positioned on the rotating hinge part; a link including a first end configured to move along a guide part of the cam plate, and a second end configured to rotate the camera when the housing rotates; a driving part configured to apply a driving force so that the housing rotates; and a control part configured to: determine a folded state of the housing by controlling the driving force applied from the driving part based on a vehicle speed, and rotate the camera simultaneously with the housing based on the folded state of the housing so as to maintain a previously set angle of a camera view, wherein the housing and the cam plate are rotatable in a reverse direction when the camera monitoring system is moved beyond a fully open state. ### Claim 2 (depends on 1) The camera monitoring system of claim 1, wherein the guide part disposed on the cam plate comprises: a first guide part configured so that the camera is rotated based on a rotation amount of the housing; and a second guide part configured so that a camera lens rotates and moves into the housing when the housing has been folded. ### Claim 3 (depends on 1) The camera monitoring system of claim 1, wherein the link is configured so that a length from the coupling shaft to the first end of the link varies when moving along the guide part. ### Claim 4 (depends on 3) The camera monitoring system of claim 3, wherein the link is configured to slidably move along a groove disposed on a case configured to surround the driving part. ### Claim 5 (depends on 1) The camera monitoring system of claim 1, wherein a part of the housing facing a driver is configured to include a mirror part. ### Claim 6 (depends on 1) The camera monitoring system of claim 1, wherein the control part is configured to control a rotation amount of the housing based on the vehicle speed, and to rotate the camera in order to maintain the previously set angle of the camera view based on the rotation amount of the housing. ### Claim 7 (depends on 1) The camera monitoring system of claim 1, further comprising an air injection nozzle and a washer fluid nozzle disposed adjacent to a camera lens. ### Claim 8 (depends on 7) The camera monitoring system of claim 7, wherein the air injection nozzle is fluidly connected to an air compression pump and the washer fluid nozzle is fluidly connected to a washer fluid pump so that injected amounts of air and washer fluid are controlled by the control part. ### Claim 9 (depends on 1) The camera monitoring system of claim 1, wherein the cam plate is fixed with respect to the base when the camera monitoring system rotates in a forward direction.
