When an animal approaches, the infrared motion detector activates the emission of ultrasonic sounds, which scare it and force it to move away from the area. The sensitivity of the sensor is manually adjusted to adapt to its space. The device is suitable for repelling dogs, cats, ferrets, rabbits and foxes. It has two rechargeable NiMH 1.2V 800 batteries and is automatically recharged via the built-in solar panel. Its range reaches up to 60 sq.m.
