ASy - Alert System v1.9.1

"Advanced Security Framework for Screen Surveillance & Geofence Protection"

ASy - Alert System is a sophisticated multi-layered security engine designed for high-stakes industrial environments. It integrates visual motion intelligence with real-time geospatial geofencing and heading deviation alerts, providing a complete 360-degree security perimeter for your monitoring workstations and maritime assets.

Core Surveillance Modules

1. Visual Surveillance (Screen Shield)

• Motion-Sensitive Monitoring: The engine analyzes specific screen areas (selected by the user) to detect unexpected changes or movement.

• Variable Sensitivity: Adjust the detection threshold to filter out background noise or focus on critical pixel-level shifts.

• Intelligent Reference Lock: Dynamically compares current screen states against a secure baseline to prevent false alarms.

2. GPS Geofence Radar

• Dynamic Zone Protection: Define complex operational zones using polygon coordinates directly within the system.

• Dual-Security Modes:

  • INSIDE Alert: Triggers if the vessel or asset stays within a restricted zone.

  • OUTSIDE Alert: Triggers if the asset drifts away from its designated safe operational area.

• Interactive Radar Display: A futuristic radar console with Zoom, Pan, and Reset capabilities to visualize your asset’s position relative to geofence boundaries.

3. Heading Deviation Guard

• Orientation Awareness: Monitors the vessel’s heading (HDG) via NMEA data integration.

• Deviation Alerts: Instantly triggers an alarm if the heading drifts beyond a user-defined tolerance (e.g., 5.0∘), essential for maintaining station or autopilot monitoring.

• Real-Time Compass Indicator: A high-contrast visual compass that displays the current vs. target orientation.

4. Adaptive Alert Tones

Customizable audio alert profiles to match the urgency of the situation:

• HIGH: Piercing high-frequency tone for critical breaches.

• LOW: Subdued frequency for minor warnings.

• WARBLE: Alternating frequency for immediate attention in noisy environments.
