INTRODUCE

The ground-based forest fire monitoring station utilizes dual-spectrum (thermal and optical) PTZ camera technology combined with artificial intelligence (AI) to enable continuous 24/7 forest fire monitoring, early and continuous detection of forest fires within a radius of up to 13.5 km. The station automatically detects smoke and flames, accurately identifies the coordinates of the fire point, and sends real-time alerts to forest rangers, forest owners, and management agencies. This enhances monitoring capabilities, shortens fire detection time, and supports the timely deployment of firefighting plans, contributing to improved forest fire prevention and control and minimizing damage caused by forest fires.
