Camera calibration and accuracy tuning

Steps to recalibrate cameras after restock or layout changes.

Updated Feb 9, 2026

Overview

Calibration ensures the system recognizes each product zone accurately.

Diagnostics

  • Verify current calibration timestamp in the portal.
  • Check for camera obstruction or lens smudges.
  • Confirm product zones match the active planogram.

Resolution steps

  • Clean lenses before starting calibration.
  • Follow the guided calibration flow and confirm each shelf image.
  • Save and test with a small transaction.

Preventive maintenance

  • Calibrate after significant product layout changes.
  • Recalibrate if detection accuracy drops.
  • Keep lighting consistent for the unit’s location.

When to contact support

  • Calibration fails repeatedly.
  • Camera feed is blank or distorted.

Expanded guidance

  • Confirm all steps are documented so the next technician can reproduce the results.
  • Capture before/after metrics (errors cleared, sales restored, or uptime improved).
  • Review machine, reader, or route settings to ensure they match location standards.

Common pitfalls

  • Skipping a controlled test leads to false positives.
  • Updating hardware without documenting configuration changes.
  • Forgetting to verify payout, refund, or reconciliation data after changes.

Next-step checklist

  • Run a final test with known-good inputs.
  • Log the outcome with date, time, and device identifiers.
  • Schedule a follow-up check if the location has high traffic or seasonal demand.

Additional details

Operational notes

  • Document changes with time, machine ID, and location name.
  • Verify settings, pricing, and service modes after each fix.
  • Capture before/after results to confirm resolution.

Field checklist

  • Test with known-good inputs and controlled conditions.
  • Validate telemetry, alerts, and payment logs where applicable.
  • Confirm location expectations and update the site contact.

Common root causes

  • Configuration drift after firmware or component swaps.
  • Inconsistent power or network conditions at the location.
  • Gaps in preventive maintenance routines.

Next steps

  • Monitor for 7 days and note any repeat errors.
  • Schedule follow-up if the site is high-traffic.
  • Escalate with full logs and photos if issues repeat.

Smart cooler notes

Vision system checks
