An innovative intelligent intrusion detection system is analyzed and applied, consisting of infrared image collection and pre-processing module, data transmission module, intelligent analysis and automatic alarm module, in- frared imagery pre-processing is achieved through 2-D discrete wavelet transform algorithm, considerably minimizing noises and enhancing details. Synergistic action of intelligent analysis and automatic alarm are achieved through intelli- gent comparison between extracted imagery and target models. Innovative deployment plan of thermal infrared cameras is applied to avoid blind zone of intrusion detection. Through mix deployment of clockwise and anti-clockwise camer- as, full coverage of security perimeter is achieved efficiently. The proposed intelligent intrusion detection system is ap- plied, and its results are acceptable, being of great efficiency and economic advantage.
