Motion activated dog & cat repellent can drive away the animals with ultrasound. Humans cannot hear such high-frequency tones, but animals can hear them very well. The frequency of the ultrasonic signal changes constantly in the range between 20 and 60 kHz. It is easy to ignore steady noises, but not those that vary. This prevents habituation.
Status LED for visual confirmation. The pest control device has a status LED so that you can monitor the activity of the electronic animal repellent.
Motion activated pest control device. The device recognizes the motion of the animals with an infrared motion sensor (PIR). This component also recognises the animals from their body heat. The cat & dog repellent has a sensitivity control to set range of the motion sensor.
Battery operated dog & cat repellent. 3 customary AA (alkaline) batteries supply the device with power. It is therefore also suitable for use in autumn and winter.
