5.3 Electronic Camera Adjustment

Lens Adjustment Module (LAM) Hook Up
The Camera FOV is adjusted using the Vantage Lens Adjustment Module (LAM). The LAM is hooked up in
series with the Vantage camera during camera installation.
After attaching the LAM to the camera (see section 5.2.5 or 5.2.6 above) follow the directions below to
correctly set the Field Of View.
Lens Adjustment Module (LAM) Field of View Adjustments
There are two buttons on the LAM which allow you to control the zoom, wide angle (zoom out) or
telephoto (Zoom in) and two buttons which allow you to control the focus adjustment. In addition there
are two buttons marked 'Set' and 'Auto Focus'
1. Turn "On" the monitor if your LAM is equipped with one. Camera video should now be visible. If
the LAM is not equipped with a monitor, camera video should be visible on the cabinet monitor.
2. Use the LAM "Zoom Buttons" to obtain the proper Field Of View (FOV). Remember: The FOV
should be a minimum of four lanes wide and medium sized vehicles at the stop bar area should
be about the size of your thumb when using a nine inch monitor. Horizon should never be
included as part of the FOV.
3. Once the proper FOV has been obtained, press the LAM "Auto Focus Button". It is best to wait
till traffic is stopped before attempting to Auto Focus. A pink rectangular shape will appear in
the lower right corner of the monitor image indicating that the camera is trying to focus. Never
press any other buttons while the rectangular focus indicator is still visible.
4. When proper focus has been obtained you must save the camera settings. To do this, press the
LAM "Set Button". The "Save Light" on the LAM module should illuminate indicating the settings
are being saved. Do not press any buttons while the Save Light is still on. If the camera settings
are not properly saved, the camera will return to its factory default settings whenever camera
power is cycled.
5. This completes the camera setup process. Disconnect the LAM module and reconnect the
camera video cable to the Edge processor and remove power from the LAM module.
More details on camera setup and correct field of view can be found in the Edge Processor, RZ4‐
Advanced Camera and LAM user manuals.
You should now see the video image displayed on the monitor in the traffic control cabinet. If you have
a LAMVIEW with a built in video monitor the image should be displayed on the LAMVIEW monitor also.
If a video image is not displayed, check the following:
a. Are the camera power cables and video cables connected correctly? Recheck the cable
connections by referring to the previous diagrams and table found in this section.
