4 System setup
This section provides a generic procedure for aligning one or more Drive5 system and associated
equipment 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) being
observed. The process for aligning a camera mounted at the side of a lane is essentially the
same as aligning a single camera mounted directly overhead.
The unit employs vehicle detection that will automatically trigger the camera (see Section
4.7). To determine where the vehicle will trigger, the EN Setup program can be made to
display a trigger area region. This function is enabled by clicking on Debug Output Mask in
Section 1 of the EN Setup camera properties
and selecting ”On Image Graphics” as shown
below.
This region shows the area where the camera will detect a moving vehicle. This will give the
approximate trigger line. Since the unit is using motion detection technology, the trigger line
will 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 or
Ethernet signal to the Drive5 system whenever the back (or front) of a vehicle crosses a fixed
line 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. Make sure
you are using the latest version by checking at www.jai.com. Please refer to the EN Setup
Program User’s Guide if you are unfamiliar with this software. JAI offers engineering support
