Detailed System Requirements

Visual Ground Truth via Optical Integration

Technical Insight: This sensor fusion enables true dual-factor authentication. Automated hourly captures, event-triggered images, and live streaming allow control room operators to visually verify flow conditions, bank erosion, and debris blockages in real-time, eliminating reliance on unverified numerical spikes.

  • Automated hourly capture
  • Live streaming on demand
  • Event-triggered capture during rapid water level changes
  • Remote camera tilt adjustment for optimal monitoring
