How to download and use the DocCam Viewer Chrome Extension

Looking for an alternative to the Lumens Ladibug software? You’re in the right place! DocCam Viewer is a custom extension designed for use with Lumens document cameras that works similarly to the official Ladibug software. This guide will go into how to install and use the extension for everyday use in the classroom.

Installing and Opening the Extension

To install the extension, click the following link, open up Google Chrome and click on the following URL: DocCam Viewer and click the blue “Add to Chrome” button, and click “Add extension”

After performing these steps, the extension is now installed onto Chrome and is ready to be used. To access the extension, look for the puzzle piece icon on the top right of the browser. Click on the icon and look for DocCam Viewer in the list. Once found, hover your mouse over the extension and click on it to open the extension. It will open up in a new tab.

This is what you will see when you open the extension, it will appear in a brand new window.

Preparing the extension for classroom use

Once the extension is open in a new window, you will see a window open like the above screenshot. Before you’re able to use the extension, you need to select the document camera, if it is not automatically selected. If it does not automatically appear, click inside the drop down box to check if it appears. If not, reconnect the document camera to your computer, close the extension, and then reopen it to try again. Once you see your document camera in the box, click the “Select” button. It will then ask you to choose a resolution. You can click in the dropdown box to select a different resolution, or stick with the default option. It is recommended to use the highest possible resolution available, but what one you choose is up to personal preference.

Once you choose a resolution, click the “Select” button to move forward. You should now see your document camera in action. Note: These settings can always be changed by clicking the video camera button on the bottom left side of the screen while in the extension.
