Item Name: Animal Repeller Bird Cat Dog Scarer Deterrent Pest Repellent Mouse Repeller. Infrared Sensing Angle: 110 DegreesDetection range:6-8 meters depending on animals size (the bigger size, the larger range).Type: ltrasonic Animal RepellerRed LED :indicates the unit is activated.If there are a few days as cloudy or rainy, you must charge the batteries as long time sunshine as possible.Charging current250mA. (Charger selection:5V,500mA-1A).Power supply:solar power and 3AA size 800 mAhNi-MH rechargeable batteries.The Longest Working Distance: 8mInfrared sensor angle:110 degrees100% Brand New,High Quality!Description:The product uses an infrared pyroelectric sensor. The sensitivity of the sensor to the animal is related to the direction of movement, insensitive to radial motion, and most sensitive to -cut motion. Means: If the animal is stationary or is approaching the product in a straight line without -moving, the infrared light cannot be sensed and the product cannot work on the animal.Features:1. How It Works: The Repeller scare away unwanted animals and pests through the Passive Infrared sensor (PIR) detects motion and triggers the ultrasonic speaker emitting a mixture of ultrasonic, sonic and powerful flashing LED strobe lights. The irregular and variable frequency makes it more effective to drive away the most aggressive animals which may adapt and become immune to a certain frequency band.2. New Cutting-edge Technology: Dual Speaker Design and Motion Sensor extend acoustic coverage up to 5000 sq. ft. The right and left angle of the radiation range is 210 degree, once animals enter within 30ft animal repeller, motion sensor will emit ultrasonic waves and LED lighting makes the animal feel uncomfortable and run away.3.
