1. Motion Sensor DesignThe PIR motion detector system can detect movements. Then the animal repeller emits a powerful ultrasonic sound and a flashing LED strobe light to deter animals from the protected area. 2. Solar Powered The ultrasonic animal repeller for outdoor use is equipped with a solar charging panel. It can convert light energy into electrical energy for storage, reducing the use of traditional batteries. It is made of highstrength and durable ABS material. Its special IP65 waterproof performance ensures a longer life in various extreme weather conditions. 3. This squirrel repellent has a 120degree infrared sensor angle and a detection distance ranging from 25 30 feet depending on the animals' size. For the first use, charge the solar panel in direct sunlight for 2 days. After assembling the cat deterrent, select a proper place to insert it, ensuring sufficient direct sunlight and covering the area to be protected, preferably about 9 10 inches above the ground. 4. How to WorkThe blue light indicates the charging status. Turn on the switch under the raccoon repellent head, and the REDLED light and ultrasonic signal will activate for 15 seconds. During this time, there is sound for 2.5 seconds and the whiteled light flashes. After this activation, the raccoon deterrent will move to the standby mode until the PIR sensor detects motion.
