Put the document itself on the screen.

Two ways to capture what is on the desk: a 16 MP wall-mount document camera that folds flat against the wall and swings out over A4 paper, and the JH-F702H desktop visualizer with a Sony 8 MP sensor and 10× optical zoom for detail work. Both feed the classroom display over HDMI or USB, with no driver install and no software licence.

Selection

Fixed position or shared desk

Choose wall-mount when

The teacher works at the same desk every lesson and the room needs the desk surface back. The arm folds to 55 mm and stays out of the way; when it opens it covers a full A4 sheet in one frame, so nothing needs moving.

Choose desktop when

The camera travels between rooms, or the subject needs magnification. The JH-F702H adds 10× optical zoom, 4K@30 output and autofocus on detail — circuit boards, textiles, printed text, lab samples.

Both connect the same way

HDMI into the classroom display, USB (UVC) into the recording host or a laptop. No driver install, no licence, no proprietary software — which is why they drop into existing rooms without a new control system.

Paired with capture. Both cameras feed our recording terminals and JH-C2 conference host directly — the document view becomes one of the recorded channels. Ask for a signal-flow drawing.
In the Classroom

Where a visualizer earns its place

  • Mathematics and science — step-by-step working shown live instead of written twice
  • Vocational training — tool handling, wiring, stitching and assembly demonstrated close up
  • Assessment review — student work displayed to the whole class without copying
  • Remote teaching — the visualizer as a UVC camera inside Zoom, Teams or the recording host
  • Library and archive — fast scanning of book pages and documents
