An invisible column electromagnetic field protection zone is formed between the two leakage cables laid. When the human body and the metal body move in this area, the electromagnetic field disturbance is caused and detected by the detector, generating an alarm signal. For non-metallic body or non-human body, such as branches, due to extremely weak interference to the electromagnetic field, although moving in the protective area, it cannot cause disturbance of the electromagnetic field, so it will not alarm. By adjusting the sensitivity of the detector, the interference of small animals, such as puppies and kittens, can be filtered out, so as to achieve effective protection.
