Disclosed is an intelligent door and window anti-intrusion device. The anti-intrusion device comprises an illumination device, a video collecting module, a comprehensive information collecting module, an alarm sending module, a signal processing module and an illumination control module. The intelligent door and window anti-intrusion device is characterized in that the illumination module provides an illumination light source for video collection of the video collecting module; the video collecting module begins to collect surrounding video information when the illumination module is started; the comprehensive information collecting module collects surrounding information in real time and provides the surrounding information for the signal processing module in real time; the illumination control module decides the illumination module to be started, and the illumination control module decides the illumination module to be started according to a processing result of the signal processing module on the surrounding information; the signal processing module distinguishes intrusion behaviors according to the video information and the surrounding information, and therefore whether the alarm sending module is started or not and whether an alarm signal is sent or not are decided. The invention further provides an anti-intrusion system and a door control system. The anti-intrusion device and system have comprehensive analysis capacity on information and intelligent recognition capacity on the intrusion behaviors, and false alarms are obviously reduced.
