We have developed a low-cost, battery-powered deer deterrence system using AI-based sound and motion detection. The system is designed to activate upon detecting deer presence, emitting a combination of ultrasonic sounds and visual deterrents, such as flashing lights. These features can be tailored with varying intensity, frequency, and patterns to scare away deer without causing harm. The system can be strategically deployed in large open spaces or agricultural fields, providing a long-term, maintenance-free solution to protect crops, property, and roads.
