Precise repelling Advanced ultrasonic technology combined with PIR infrared sensing detects small animals such as cats, foxes, and squirrels by body temperature and movement trajectory. When detected, it immediately releases 12 50KHz frequency sound waves. The emitted sound strongly deters animals while remaining completely inaudible to humans, ensuring your daily life is not disturbed. Widely covered detection range The PIR infrared system provides a detection angle of 110 degrees and an effective sensing distance of 8 10 meters, forming a protective net around the area. When small animals enter this zone, the system accurately identifies them and activates the ultrasonic repel within 0.3 seconds. It effectively covers corners of courtyards and deep garden areas, capturing invasion signals in all directions with no blind spots. Solar power supply Equipped with conversion efficiency solar panels, the device automatically absorbs light during the day and stores energy in the built in battery. An intelligent sensing energy saving mode automatically switches to a low power state when no small animals are approaching, preserving standby readiness. Humane and harmless This ultrasonic solar animal repellent provides a chemical , humane deterrent, designed to repel small animals without injuring or killing them. It offers an effective solution for those bothered by animals but who prefer not to cause harm. Use scenarios Garden boundary protection: Place the device at a corner along the garden perimeter to deter cats, foxes, and squirrels from approaching flower beds or vegetable patches, thanks to rapid 0.3 second activation and wide 110 degree coverage. Courtyard and patio keeping: Install at strategic courtyard corners to form a protective net around seating areas and landscaping, ensuring there are no blind spots and that invaders are detected quickly from multiple directions. Remote or sun exposed areas with no power: Use in sunny outdoor locations where access to electricity is limited; the solar panels charge the built in battery and provide ongoing operation with energy saving standby when not in use.
