A device for remotely controlling the position and orientation of a camera borne by a vehicle includes a first support member including two arms and an intermediary bracket. The arms have first ends pivotally mounted in a substantially vertical plane to the vehicle for movement in the vertical plane and about the substantially vertical plane, and opposite, second ends pivotally secured to the intermediary bracket to form a pivoting parallelogram structure, with the intermediary bracket always remaining in a substantially upright position during the movement of the arms. A parallelogram jack is pivotally secured between a substantially fixed point of the parallelogram structure an one of the arms for pivoting the arms in the substantially vertical plane. A rotation jack is pivotally secured between a fixed point of the vehicle and at least one of the arms for rotating the arms about the substantially vertical plane. A second support member is secured to the first intermediary bracket for bearing the camera and includes orientation motors or orienting the camera in inclination and azimuth relative to the first intermediary bracket. A remote control device is provided within the vehicle for controlling the parallelogram and rotation jacks of the first support member and the orientation motors of the second support member to cause the camera to follow a travelling mobile unit.
