A vehicle intrusion monitoring system that eliminates unnecessary image
capture and transmission by controlling the timing of image capture by a
camera installed inside a vehicle. A control ECU in the vehicle intrusion
monitoring system issues a first image capture command to a camera
triggered by an abnormality detected by a sensor while the system is in
watch state. Then, the control ECU issues a second and further image
capture commands only when an intrusion detector picks up an intruder
inside the vehicle to eliminate unnecessary image capture and
transmission.
