S21

A2 large format overhead document camera

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. Along with these great features, you can use the bundled VIISAN scanning software with this smart device to get great results while scanning books. For example, it can automatically digitally flattens curved pages, erases fingers from the scanned photos, repairs the damaged edges of documents, rotates pages based on text orientation, and automatically splits double-page into separate images.
