The present invention provides a camera device for a vehicle and a focal length compensation adjustment device for each temperature, capable of compensating and adjusting a focal distance of a camera device, which is changed according to a temperature change in a vehicle. According to an embodiment of the present invention, the camera device for a vehicle includes: a lens assembly; an image sensor arranged on a substrate; a position sensor sensing a position corresponding to an interval of the image sensor and the lens assembly; an actuator module installed between the substrate and the lens assembly, and adjusting the distance between the image sensor and the lens assembly; and a controller controlling the actuator module to adjust the position to a position matched to a first detection temperature while monitoring a detection position by the position sensor (100) when the temperature change occurs based on the first detection temperature sensed by a first temperature sensor. 본 발명의 일 실시 예에 따른 카메라 장치는, 렌즈 어셈블리; 기판에 배치된 이미지 센서; 상기 렌즈 어셈블리와 상기 이미지 센서의 간격에 대응하는 위치를 센싱하는 위치센서; 상기 기판과 상기 렌즈 어셈블리 사이에 설치되어, 상기 이미지 센서와 상기 렌즈 어셈블리 사이의 거리를 조절하는 액츄에이터 모듈; 및 제1 온도센서에 의해 센싱된 제1 검출온도에 기초해 온도 변화 발생시, 상기 위치센서(100)에 의한 검출위치를 감시하면서 상기 제1 검출온도에 매칭된 위치로 조절하기 위해, 상기 액츄에이터 모듈을 제어하는 제어기; 를 포함한다.
