A projection display device is provided with a main body cabinet; a projection port which is formed in the main body cabinet to guide modulated light to an outside of the projection display device; an air outlet which is formed at least in one of two surfaces of the main body cabinet facing each other across the projection port; and an exhaust unit which discharges, to the outside, air that has been warmed by heat exchange with a member to be cooled which is disposed in the main body cabinet through the air outlet. In this arrangement, the exhaust unit includes an exhaust fan, and a deflection member which deflects air discharged from the exhaust fan in a direction away from the projection plane.

A surveillance camera comprises a base mounted on a wall, an imaging lens mounted on the base via an imaging lens support member and a switchable mounting unit, and a rotation drive device driving the imaging lens so as to rotate in a panning direction. The switchable mounting unit selects either a first posture wherein a seating mount of the base, making contact with the wall, is approximately perpendicular to an axis of panning rotation of the imaging lens or a second posture wherein the seating mount is approximately parallel to the axis of panning rotation, and mounts the imaging lens support member on the base.
