A worksheet that’s easy to read at your desk can be hard to follow from the back of a classroom. A document camera lets you show the class what’s on the page as you work. Before the lesson, check the path from the camera to the board, then test the smallest detail students need to see.
Put the camera feed on the board
Start with the computer you teach from
Connect a USB document camera to a computer that supports the camera and its viewing app. Open the app and select the document camera by name. If you see your face instead of the page, the app is probably using the laptop’s webcam. Once the page is visible on the computer, show that computer’s output on the smart board and bring the camera app into view. IPEVO Visualizer features
If you plan to plug the camera directly into the board, check whether the exact board configuration, operating system, and viewing app support the camera. For example, the KEINONE 65-inch 4K Interactive Smart Board listing offers an Android configuration and an Android configuration with a Windows OPS module. Decide which system will run the camera app and test that setup before class. KEINONE 65-inch 4K Interactive Smart Board
Frame the detail students need
Check orientation, focus, and shadows
Start with the whole page or object so students know what they’re looking at. Rotate the page or use the app’s rotation control if the image is upside down. Move the light or your hand if a shadow covers the demonstration. Then zoom in and check focus on the specific detail students need, such as a leaf vein or a small label in a diagram.

Sit in the farthest seat and check the actual live feed. If a worksheet is still hard to read, show one question at a time. If a close-up crops out the context, show the full page briefly before returning to the detail.
FAQ
Why does the board show my desktop but no camera image?
Check whether the camera feed works on the computer. If it does, bring the viewer window onto the board in Extend mode or make it the active window in Duplicate mode. If the feed is blank on the computer too, select the camera again in the app and try another supported USB port.
Can I write over the live image?
That depends on the viewer or annotation app and how pen input reaches it. Test one mark and check whether it appears on the board. If you need to keep the annotated image, try capturing a still and opening it in a whiteboard app that can export your work.
What should I check before buying a camera for an existing board?
Decide where the camera will connect and which app will show it. Check the camera vendor’s operating system requirements, then confirm the board configuration if you plan to connect directly. KEINONE support
