A TV camera supporting device to be used in a surveillance system in a building or the like includes a first supporting member receiving a TV camera fixed thereto, a second supporting member rotationally-adjustable relative to the first supporting member and connectable thereto, and a third supporting member which has an axis of rotation intersecting the axes of rotation of the first and second supporting members and is angularly rotatable about its axis of rotation to adjust a relative position between the third supporting member and the second supporting member to which the supporting member is secured after the adjustment. By adjusting the relative positions of the three supporting members, the direction of the optical axis of the TV camera can be adjusted as desired.
