SAM™ allows greater flexibility for aiming than ball-type mounts that limit range of motion
when not on center. Typical ball designs have limited rotation when pointing straight ahead,
and even that is reduced when the enclosure contacts the wall and is moved off axis. By
contrast, SAM™ allows full rotation even at full sweep.
SAM™'s range of rotation is 90°. EVID™'s curved cabinet allows it to rotate much further than a
rectangular or trapezoidal box).
