Improve detection in low-light conditions.
Updated Feb 9, 2026
Overview
Vision accuracy depends on clean lenses, stable lighting, and planogram compliance. Improve detection in low-light conditions.
Diagnostics
- Check lens clarity and camera obstructions.
- Verify lighting conditions near the unit.
- Confirm products match the active planogram.
Resolution steps
- Clean lenses and remove shelf obstructions.
- Re-shelf products to match zones.
- Run calibration after layout changes.
Preventive maintenance
- Clean lenses every visit.
- Avoid stacking products or mixing SKUs.
- Keep a planogram reference photo on route.
When to contact support
- Confidence scores drop after calibration.
- Camera feed is blank or distorted.
- Repeated mismatches with correct layout.

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.
