2. Use random frequency ultrasonic sound to drive many kinds of insects away. |
3. The ultrasonic sound is not harmful and can not be heard by human. |
4. The controller emits radio and received by receiver worn by dogs. |
5. The receiver determines the boundary range by the power of radio it received. |
