This section provides a generic procedure for aligning one or more VIS CAM 300/400 cameras and 

their associated equipment at a site. If you received a specific installation manual from JAI for your 
project then follow those instructions instead of the procedure described here. 

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 over the lane. 

•  The site employs an accurate vehicle detection device that outputs a discrete TTL signal to the 

VIS 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. Examples of such triggering devices 

are: Peak’s trafficLoop, STI’s Vehicle Detector light curtain, and JAI’s Laser Vehicle Detector. 

•  License plate reading or vehicle matching is performed on the images produced by the VIS 

system. In these cases, precise location and alignment of the cameras is critical to project 
success. If the VIS images are only for human interpretation, then achieving the exact camera 

alignment is much less critical. 

•  The installer is familiar with using the ENSetup program supplied by JAI. Please refer to the 

ENSetup Program User’s Guide if you are unfamiliar with this software. JAI offers engineering 
support and software tools to help select the optimum camera and trigger locations to meet 
your specific project needs. Contact ITS Engineering Support at (408) 383-0300 for further 

information about obtaining JAI assistance. 

•  Make sure you have a JAI supplied setup computer with the ENSetup program installed. 
•  The Setup computer needs to have an Ethernet network adapter installed (preferably 1 Gigabit 

Ethernet Adapter) and the TCP/IP network configured with the correct IP-address, subnet-mask 

and default-gateway. 

•  The Setup computer and the cameras need to be on the same subnet. The cameras are shipped 

with the standard IP-address “10.0.0.65” and subnet-address “255.255.255.0”, and the Setup 
computer needs to be assigned an IP-address “10.0.0.xx” in order to automatically discover the 

cameras using the ENSetup program (NB! “xx” must not be “65”). 

•  All cameras have to be given unique IP-addresses before the alignment begins. This is done using 

the ENSetup application. 

•  Confirm all VIS CAM components and cables are properly connected.
