The invention discloses an intelligent door and window anti-invasion system which comprises a video collecting module, an audio collecting module, a heat releasing infrared detecting and alarming module, a vibration detecting module, a glass crushing detecting module, a door magnetic detecting module, a signal processing module, an alarming transmitting module and a power supply managing module. According to the intelligent door and window anti-invasion system, possible illegal invasion behaviors in door and window areas are found through a multi-dimensional detecting manner. Illegal invasions or guest visiting or normal coming in and going out by the head of a household can be accurately recognized. Pictures of visiting of a guest are sent to terminals like a cellphone of a host at home or real-time and intuitional alarming signals with audio and video or pictures as carriers are sent to alarming receiving and processing terminals such as the cellphone of the head of the household, a residential area monitoring computer and the like. Meanwhile, alarm lamps and alarm signals are linked so as to achieve sound-light alarming in a field where an incident happens, or other relevant devices are linked. In addition, the intelligent door and window anti-invasion system is arranged outdoors so that illegal invasions are wiped out to the largest degree before the illegal invasions actually happen.
