Abstract

Disclosed herein is an intrusion detection apparatus which includes an infrared emission unit for emitting infrared beams and an infrared reception unit for receiving the infrared beams. The infrared emission unit adjusts an emission direction in which the infrared beams are emitted based on information received from the infrared reception unit, and adjusts an optical axis which is formed with the infrared reception unit depending on whether infrared beam values corresponding to the adjusted emission direction fall within the normal range. The infrared reception unit adjusts a detection direction in which the infrared beams are detected based on information received from the infrared emission unit, and adjusts an optical axis which is formed with the infrared emission unit depending on whether infrared beam values corresponding to the adjusted detection direction fall within the normal range. The intrusion into a relevant region is detected using the optical axis.
