VIS CAM 300/400 Installation Manual

System Set-Up

4.1.8 Properly Position the License Plate Stand

Using your portable plate stand, position a license plate:

• at the minimum expected trigger distance from the camera.

• at the minimum expected plate height above the road.

• at the location along the trigger line where the center of the horizontal field-of-view of this camera

is desired.

Rotate the plate on the stand until the top and bottom edges are level with the vehicle parked behind the

trigger line (to within a + or – a couple of degrees). Secure the plate on the plate stand so that the

adjustments you have just made do not change.

4.1.9 Perform Initial Lens Adjustment and Camera Aiming

1. Back away all of the thumbscrews on the lens holder until they do not touch the knurled adjustment

rings on the lens.

2. Make sure the lens aperture adjustment is fully open (rotate the third ring from the front of the lens

fully counter-clockwise until it stops at the f1.2 setting). Secure the thumbscrew that lines up with

the aperture ring until it just presses against the ring. Next tighten the thumbscrew that lines up

with the knurled ring closest to the camera body until it just presses against the lens. Do not tighten

any Lens Holder thumbscrews beyond a slight pressure against the lens.

3. Loosen the roll, pan, and tilt bolts on the JAI camera mounting head until each axis can be easily

adjusted by hand but any particular setting will stay in place after you let go.

4. Power on the Setup computer and then start the ENSetup program. Press the “Video Window” but-

ton to open the Video Window and then select the camera for adjustment from the tree-view on the

left side of the window. Press the “Live” button in the toolbar to start the video streaming. Press the

“Tilt Line” button to show the alignment guidelines. The “Tilt Line” can be moved using the

mouse, or if the “Tilt Line” is selected, using the arrow-keys.

5. Interactively adjust the roll, pan, and tilt of the camera mount and the lens zoom and focus rings:

6. Adjust the lens focus ring (and camera pan and tilt as necessary) to obtain a focused image of the

plate on the plate stand. If at any time you cannot fully focus the plate because the focus ring on the

lens has reached the end of its turning movement, perform the back-focus procedure described in

the JAI document titled “Zoom Lens Back-Focus Procedure.”

7. Adjust the lens zoom ring to obtain a plate width approximately equal to the distance between the

short vertical sizing marks that appear above the tilt line. Readjust focus as necessary. See

Figure 31 for more information.
