The camera should be aimed according to the field-of-view required to meet the detection objectives for the installation. This is the area in which detection is to take place. The field-of-view is set by adjusting the barrel rotation, pan, tilt and zoom settings during the aiming procedure.
For example, in Figure 2-5 and Figure 2-6, the camera (Cam) is set to detect southbound traffic. The solid green line represents where the camera should be aligned when it is installed (see Camera Placement). The dashed red line indicates approximately where the outside edges of the field-of-view will be; showing extra lane width on either side of the stop line. The 16 x 9 HD format of the IntelliSight Camera provides a wider field-of-view at the stop line than other 4 x 3 format Autosocpe products.
