The alignment of the detector is extremely intuitive, fast and accurate. Both the IR transmitter and the CMOS imager are contained in the eyeball that can turn freely in all directions. The eyeball moves +/- 20 ° in the vertical direction and 50° in the horizontal direction. Four arrows that indicate the direction to move the eyeball, will guide the user to find the imager’s perfect alignment with the reflector. To get started swiftly at long distances, a laser tool can be inserted in the eyeball to allow finding the reflector quickly and then fine-tuning the eyeball to the optimum alignment. Once the optimum alignment is finalised, signalled by all green arrows and LED, the eyeball is locked by tightening the lever on its side. A paintable cover is then placed over the front to hide the alignment arrows, locking mechanism and secures the locking lever in locked position.
