How it works The repeller scares away unwanted animals and pests with the Passive Infrared (PIR) sensor, detects movement and triggers the ultrasonic speaker to emit a mix of ultrasonic, sound and powerful flashing LED flashes. The irregular and variable frequency more effectively wards off more aggressive animals that may adapt and become immune to a certain frequency band. Long range The PIR infrared motion sensor has an angle of up to 120 degrees and a detection range of up to 10 meters. This activates the cat repellent to emit a high frequency sound which is irritating to the cat and almost inaudible to humans. Use safety and human design The cat deterrent animal repellent should lead the animal only without chemicals. only 13.5 kHz to 40 kHz ultrasound is emitted to chase them away. Does not harm the human body. And won't hurt your own cats, dogs or other animals. Dual USB and solar charging The ultrasonic animal repellent scares away cats with 4 built-in AA batteries, charged by solar power during the day.

IP64 waterproof and weatherproof This product has IP64 waterproof design. Even if it gets wet in the rain, you can still use it without any problem. The unique seal and design allow you to attach the device anywhere. For example in gardens, garages, terraces, ponds, but also attics, etc. Note: Do not soak in water. Mode settings: 0: turn off 1: 13.5kHz - 20kHz, which can drive away animals such as mice and hamsters. 2: 15.5kHz - 25kHz, which can hunt animals such as big dogs, foxes. 3: 25kHz - 34.5kHz, which can drive away animals such as small dogs, cats and mice. 4: Powerful flashlight that can hunt animals such as boars, weasels and nocturnal animals. 5: 13.5kHz - 40kHz, all functions from level 1 to 3, the deviation frequency will increase from level 1 to 3, then the strong flashing light will be on. Specifications: Material: Solid ABS Power: 4 x AA lithium batteries (charged via solar panel or USB line); Maximum detection range: 10 meters, depending on the size of the animal and the environment; Infrared sensor angle: 120 degrees 1. Sometimes human can perceive ultrasonic waves. Keep the product away from living areas. Do not place the product in areas where babies and children are active. 2. If installing the unit in the ground, carefully insert the pole into the ground. Instead of hitting the device directly, drill a hole to hold it in place.
