The range of detectable sound frequencies for many animals and insects is far more sensitive than that of a human being. It is this range of frequencies that forms the basis for this technology. Ultrasound waves are high frequency sound waves which can be detected by animals and insects but are completely undetectable to the normal human ear. The use of ultrasound influences the behavior of the animals and insects, discouraging them from approaching an area in which a device is being used. Each model is calibrated to a certain frequency and power specific to a particular pest type, providing a safe and effective repellent.The high efficiency of our products is achieved through effective utilization, ensuring they are placed in locations which optimize ultrasound coverage. For example: ultrasound is emitted from the device radially in all directions, Hard materials such as walls, ceilings, furniture, glass, allow better wave coverage and spreading, while soft materials such as cardboard, curtains and carpets absorb some of the waves.Exclusive for India:The responsibility for import and distribution of RADARCAN products in India is solely entrusted to NATASIAN CORPORATION Pvt Ltd, a company committed to attaining customer satisfaction through the supply of quality products only.
