Feature: 1. Infrared Induction: Electronic animal repeller adopts infrared induction. When the infrared sensor detects that the animal has moved away, the LED indicator will automatically turn off. 2. PIR Motion Detector: When it senses that there is a moving animal in the detection range, it will automatically send out a sound wave frequency to drive the animal away and the LED indicator lights up accordingly. 3. Adjustable Frequency: Dog repeller adds light flashing, sound, frequency adjustment, and sensitivity adjustment functions to drive animals more targeted and better. 4. Safe to Use: Animal repellent just drives away animals without any chemicals, it emits ultrasonic frequency to drive them away without any harm to human body. 5. Small Portable: The solar animal repeller is a portable design that can be installed anywhere in your home, garden, or yard, and can be used with low voltage power and batteries.

Weight: Approx. 430g / 15.2oz. Package List: 1 x Host2 x Connecting Rod1 x User Manual1 x Connecting Line Note: 1. The product uses infrared pyroelectric sensor. The sensitivity of the sensor to the animal is related to the direction of movement. It is not sensitive to radial movement, but sensitive to transverse movement. It means: if the animal is stationary or approaching the product in a straight line, without crossing cutting movement, the infrared rays cannot be sensed, and the product cannot work on the animal.2. It adopts the principle of infrared detection, when it detects small animals, it sends out ultrasonic waves to drive away small animals. It can help you stay away from pesky stray dogs, cats and other small animals to protect your property, your garden and your yard.3.Ships with built in battery.
