Frequently Asked Questions
What is a document camera used for?
A document camera like the DC-21 is used to capture and display physical materials in real-time. Common applications include classroom instruction (displaying textbook pages, handwritten notes, and experiments), business presentations (showcasing product samples and prototypes), medical training (examining specimens and procedures), and technical demonstrations (inspecting detailed components and assemblies). The HD 1080p resolution ensures viewers can see fine details clearly on large screens.
Can the DC-21 document camera record video?
Yes, the DC-21 can record video with synchronized audio thanks to its built-in microphone. You can save recordings directly to an SD card or transfer them to your computer for editing, archiving, or sharing with students and colleagues. This makes it ideal for creating instructional videos and lesson documentation.
How does the 12x optical zoom improve presentation quality?
The 12x optical zoom allows you to magnify small details—such as fine print, intricate diagrams, or microscopic specimens—without degrading image quality. Unlike digital zoom, optical zoom maintains sharpness and clarity, making it perfect for highlighting specific content during live presentations without losing definition on the projected display.
Is the DC-21 portable document camera compatible with interactive whiteboards?
Yes, the DC-21 connects via HDMI to projectors, interactive whiteboards, and displays, making it fully compatible with modern classroom and presentation setups. Its portable design means you can easily move it between rooms and venues, and the Freeze and Capture buttons provide intuitive control during live sessions.
