Crafted from PC material, the Qtenboard Document Camera features a circular arc design with no acute angles, effectively preventing scratches during use. Its holding plate adopts a magnetic absorption mechanism—this not only keeps the plate from falling, enabling easy opening and fixing but also avoids the high failure rate issue of traditional mechanical locks, ensuring long-term reliable use.
Automatically analyzes issues like hardware connection, graphics card driver, and camera occupation; reconnects automatically when the device is unplugged/plugged.
Supports barcode/QR code recognition, PDF conversion, OCR text recognition (Chinese/English, copyable to Word/PPT), and spot light photographing.
Allows free handwriting (color/thickness adjustable), quick shape drawing, and synchronous annotation with screen rotation/zooming; double-click to erase all annotations.
Supports 2/4-split screen comparison, brightness/contrast adjustment, and one-click restore to default.
