Abstract: In recent years, with the rapid development of the economy, the indoor intelligent monitoring is getting more and more attention. This paper proposes an indoor intelligent monitoring system that fuses the audio and video due to the current states. Firstly, the system conducts pretreatments on the signals acquired by the microphone array. Then, after locating the source position, it realizes the real-time steering of the dome. Finally, the detections are made on the circumstances of the monitoring scenes using the anomaly monitoring detection technique so as to determine whether trigger the alarm. Test results in a real indoor environment indicate that the design has met prospective requirements with the sound location accuracy rate and the anomaly detection recognition rate can reach over 87.5% and 71.67%.
