Abstract: A system and method that is both effective and accessible. The system is machine-learning enabled, reliable, scalable, versatile, and may be efficiently installed. The system will improve US, state, and local fire suppression efforts because more homeowners will successfully evacuate if they have access to protection. Also, it may allow more fire crews to focus their efforts on the flame front, rather than suppressing structural spot fires in areas where the systems are installed. The system significantly reduces insurance and governmental suppression costs which would provide significant incentives to homeowners. The system minimizes fire related damage to the home, may operate independently from local utilities, may remain in service with minimal attention from the homeowner, and minimize the impact of system discharge on the environment. The system does this by precisely targeting firebrands and discharging only the amount of aqueous solution needed to extinguish the firebrand.
