― 17 ―4 System setupThis section provides a generic procedure for aligning one or more Drive5 system and associatedequipment at a site.The example installation process described in this section assumes that: The cameras are being mounted on an overhead structure directly over the lane(s) beingobserved. The process for aligning a camera mounted at the side of a lane is essentially thesame as aligning a single camera mounted directly overhead. The unit employs vehicle detection that will automatically trigger the camera (see Section4.7). To determine where the vehicle will trigger, the EN Setup program can be made todisplay a trigger area region. This function is enabled by clicking on Debug Output Mask inSection 1 of the EN Setup camera properties and selecting ”On Image Graphics” as shownbelow.This region shows the area where the camera will detect a moving vehicle. This will give theapproximate trigger line. Since the unit is using motion detection technology, the trigger linewill vary a little depending on the speed of the vehicle. If the installation utilizes other modes for triggering, the unit can also accept a discrete TTL orEthernet signal to the Drive5 system whenever the back (or front) of a vehicle crosses a fixedline across the road. This line is referred to as the “trigger line” in this document. The installer should be familiar with using the EN Setup program supplied by JAI.
