The S21 is a perfect A2 large format overhead document camera, ideal for scanning large format journals, manuscripts, newspapers, and maps. With the built-in 20.1MP high-resolution image sensor, the S21 allows taking snapshots, books, documents, business cards, 3D objects, and record videos. With the embedded OCR feature you can convert all the scanned files into PDF or editable Word/Excel/ePub/Txt files.
