The present invention relates to a companion animal management device for not only being able to monitor a companion animal in a distance, but also notifying a guardian in real time when the companion animal is in an abnormal state, installed in a surveillance area, and photographing companion animals. A camera unit for generating the captured image as image information； A microphone unit for acquiring the barking sound of the companion animal and generating the acquired sound as sound information； A memory unit that presets and stores a limit barking time for determining an abnormal barking state of a companion animal, and stores a property of sound information according to a sound and intensity of a frequency and a voice of a guardian； The frequency attribute of the sound information generated by the microphone unit is analyzed and the duration is counted, and the attribute of the analyzed frequency is compared with the attribute of the sound information stored in the memory unit. If the property is the same, a notification signal is generated when the duration of the sound information is equal to or greater than the limit barking time by comparing the duration of the counted sound information with the limit barking time stored in the memory unit, and an image generated by the camera unit A control unit for transmitting information or a notification signal； A guardian terminal unit for receiving video information or a notification signal from the control unit and notifying the guardian； And a speaker unit for outputting a guardian's voice stored in the memory unit when it is determined that the companion animal is in an abnormal barking state.본 발명은 원거리에 있는 반려동물을 모니터링할 수 있음은 물론, 반려동물이 비정상적인 상태인 경우에 보호자에게 실시간으로 알려주기 위한 반려동물 관리 장치에 관한 것으로, 감시영역 내에 설치되어, 반려동물을 촬영하여 해당 촬영한 영상을 영상정보로 생성하기 위한 카메라부； 반려동물의 짖음 소리를 획득하여 해당 획득한 소리를 소리정보로 생성하기 위한 마이크부； 반려동물의 비정상적인 짖음 상태로 판단하기 위한 한계 짖음 시간을 미리 설정하여 저장하며, 주파수의 음, 세기에 따른 소리정보의 속성과 보호자의 음성을 저장하는 메모리부； 상기 마이크부에서 생성된 소리정보의 주파수 속성 분석
