WheelGuard
Professional roulette wheel integrity monitoring for casino surveillance and game protection teams. Connect multiple wheels simultaneously, detect bias in real-time, and generate evidence-grade reports.
From tap-based clocker to visual-assisted CCTV analysis — WheelGuard covers every monitoring scenario, whether you have camera infrastructure or not.
Core Modules
Multi-Table Dashboard
Monitor up to 5 roulette wheels simultaneously from a single view. Each table displays a live radial wheel visualisation with real-time hit data, chi-squared scores, z-score flags, and sector deviation analysis. Click through to full analysis for any table.
Visual-Assisted Prediction
Connect to overhead CCTV feeds, live data streams, or screen capture. Calibrate the wheel overlay in 3 clicks — centre, track edge, north reference. Auto-detects rotor speed via green-0 tracking and ball crossings for convergence-based sector prediction.
Manual Clocker
Tap-based rotor and ball speed capture for environments without camera access. Lock rotor speed, tap ball crossings, and receive real-time sector predictions using Crown Clocker physics and multi-convergence algorithms.
Roulette Analysis Suite
Full statistical analysis engine — import spin data via CSV or Excel, or use the built-in number logger. Generates chi-squared bias tests, per-number z-scores, sector deviation analysis, and drop zone heat maps with professional PDF reporting.
How It Works
Connect Tables
Add up to 5 tables via CCTV camera feed, live wheel data feed (Cammegh / TCS John Huxley), or screen overlay capture. Each table runs independently with its own stream and overlay.
Calibrate Overlay
Three-click calibration — click the wheel centre, the ball track edge, and the north reference point. The overlay locks to the wheel with adjustable track width, offset, and radius for perfect alignment.
Collect & Analyse
Spin data flows in real-time — manually, via visual detection, or CSV import. Chi-squared tests, z-scores, and sector analysis run continuously. Bias patterns surface automatically.
Report & Act
Generate professional PDF reports with visual charts — distribution bars, radial heat maps, sector donut charts, and full statistical breakdowns. Evidence-grade documentation for every wheel on your floor.
Connection Methods
CCTV Camera Feed
Connect to overhead cameras via RTSP, ONVIF, or HTTP streams. Computer vision tracks the ball and rotor automatically after 3-click calibration. Zero latency ball detection via motion-based frame analysis.
Live Wheel Data Feed
API integration with Cammegh and TCS John Huxley wheel sensors — receives spin telemetry direct from the wheel hardware. The fastest, most accurate data source available.
Screen Overlay / Window Capture
Transparent overlay on any live stream or browser window — no hardware needed. Share your screen, calibrate the wheel position, and WheelGuard tracks through the overlay.
Full Feature Breakdown
Multi-Table Operations
- Up to 5 concurrent table connections — each with independent stream, overlay, and calibration
- Switching between tables preserves all live connections — no stream interruption
- Per-table calibration saved automatically — reconnect instantly on return
- Dashboard grid view with live wheel visuals, chi-squared scores, and sector analysis per table
Data Capture Methods
- Screen capture with wheel overlay calibration (3-click setup)
- CCTV camera feed integration (RTSP, ONVIF, HTTP)
- Live wheel data feed (Cammegh / TCS John Huxley telemetry)
- Manual tap-based clocker for camera-free environments
- CSV and Excel file import with intelligent column detection
- Built-in number logger with session history
Statistical Analysis
- Chi-squared goodness-of-fit test (36 df, p=0.05 threshold at 50.99)
- Per-number z-score calculation with automatic flagging (±2σ monitor, ±3σ strong)
- Sector deviation analysis across physical wheel segments
- Radial heat map — visual representation of pocket and sector frequency
- Drop zone tracking — where the ball consistently exits the track
- Colour distribution analysis (red/black/green ratios)
Professional Reporting
- PDF reports with branded visual charts — distribution bars, radial heat maps, sector donuts
- Z-score colour coding in reports (green ±1σ, yellow ±2σ, red ±3σ+)
- Bias detection cards with chi-square value, p-value status, and flagged count
- Sector statistics with horizontal heat bars and number chip visualisations
- Full audit trail — every spin timestamped with session and source metadata
- CSV/Excel export for external analysis or regulatory submission
Use Cases
Wheel Bias Detection
Scenario: Over 500 spins, pocket 17 is hitting at 2.8 standard deviations above expected. The radial heat map shows a clear hot sector.
Action: WheelGuard flags the statistical anomaly, provides the evidence trail, and the report goes to the gaming floor manager — wheel service or replacement recommended, with full data backing every conclusion.
Multi-Wheel Floor Monitoring
Scenario: A surveillance operator connects 5 roulette tables to the dashboard. Each table runs its own live feed with independent calibration.
Action: The dashboard provides at-a-glance chi-squared and z-score status for every wheel. Anomalous tables are immediately visible without clicking through — switch to any table for deep analysis without losing other connections.
Regulatory Compliance & Audit
Scenario: The regulator requires evidence of ongoing wheel integrity monitoring. Historical spin data needs statistical review.
Action: Import historical CSV data, run the full analysis suite, and generate branded PDF reports with visual charts, statistical summaries, and audit trails. Professional, evidence-grade documentation ready for submission.
