1.The motion activated animal repeller is use solar energy.
2.The animal repeller is use ultrasonic wave.
The product uses infrared pyroelectric sensor,the sensor is associated with reaction sensitivity and movement direction of the animals.It is not sensitive to radial movement but most sensitive to transverse movement.
Therefore,if the animal is stationary or close to the product Straightly without crossing movement,infrared sensors will be unable to work on animals because of Induction failure
