VIS-CAM System

4 System Set-Up

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.

4.1Preparation for Alignment

4.1.1Pre-Alignment Checklist

•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.
