Step by Step Instructions - Guide

The Guide interface is useful to configure the correct settings for license plate capture

Log into the Web UI of the camera by typing the IP into a web browser.

Enter the username/password and click Login

• Click the Guide tab.

• Drag the yellow box to the position of the plate

• Click Local Range to zoom the picture by 2x or 4x zoom rate (if required)

• Continue to adjust the position yellow box to make it optimal plate size:

If the plate within the yellow box is larger than the optimal plate size in the example, zoom out the video image; if smaller, zoom in the video image.

It may also require reviewing proper mounting requirements/positions if any softw3are adjustments do not allow for optimal plate positioning.

• Once the plate is in optimal position, click Check Pixel. Click Yes to confirm.
