IPEVO V4K Document Camera Setup

Tested & recommended

The IPEVO V4K is our top tested recommendation for Rollsight. 8MP, excellent low-light, plug-and-play USB. Mac, Windows, and Chromebook compatible—no special drivers required.

Plug and play

The IPEVO V4K is straightforward to use with Rollsight: connect via USB, select it in the app, and you're ready to calibrate.

  1. Position the V4K so the camera head looks down at your dice tray. Use the articulated arm to adjust height and angle.
  2. Connect the camera to your computer with the included USB cable.
  3. Launch Rollsight and go to Settings → Camera.
  4. Select the IPEVO V4K from the camera list. The feed should appear in the vision pane immediately.
  5. Ensure your entire dice tray is in frame. The V4K supports high resolution (up to 3264×2448); you can use the software's capture area and calibration options to match your tray.
Success: When you see a clear view of your dice tray in Rollsight, run through calibration (below) for best recognition.

Tray surface (important for Rollsight): Rollsight works best with a black or dark tray. It's trained and tuned for dark backgrounds; light or colored trays can cause missed dice or false positives. If Rollsight struggles on your current tray, line it with black self-adhesive felt cut to size—e.g. Caydo black self-adhesive felt sheets (Amazon). This often fixes recognition issues.

Dice readability: Clear or translucent dice are harder to read; dice similar in color to the tray (e.g. dark on black) are also tougher. Dice with unusual fonts, symbols, or non-standard pips are fine once you train them—Rollsight learns from your examples.

Camera calibration options in Rollsight

Rollsight includes several calibration options to get the best recognition from any camera, including the IPEVO V4K:

  • Capture area mask: Define exactly which part of the image Rollsight uses for dice recognition. This lets you match different camera resolutions and dice tray shapes (rectangular, round, etc.) and ignore the rest of the frame.
  • Background calibration: Settings → Calibrate Background so the software knows your tray surface and lighting.
  • Rotation: Fine-tune in the Camera menu if dice appear tilted in the feed.
  • Focus: Use Camera → Calibrate Focus if available; the V4K has manual focus options on the unit.
  • Lighting Boost / Camera Normalization: Enable in Settings if the image is too dark or you want more consistent results.

Taking a minute to set the capture area mask to your tray shape and running background calibration will improve accuracy.

Tips

  • Use the V4K's buttons on the camera head for exposure/focus if needed.
  • Good, even lighting over the tray helps; the Sony sensor handles low light well but consistent light is best.
  • For streaming, the V4K appears as a standard video source in OBS, Streamlabs, etc.—see our streaming guides.

Next steps

  • Train your dice using Training mode
  • Set up VTT integration (e.g. Foundry)
  • Start rolling!
