The Superfish Bird & Cat Protector utilizes an infrared sensor to detect unwanted visitors. Once triggered, it harmlessly deters pests such as cats and birds with an alarm, ultrasonic sound, and/or flashing LED lights. It features a built-in solar panel and includes 3 rechargeable AA batteries, with an additional USB cable for recharging. The infrared sensor has an adjustable range of up to 8 meters with a 110° detection angle. The device offers a choice of 5 alarm settings and is splash-proof. The ultrasonic sound is designed to be inaudible or barely audible to humans.
