Outdoor transformer cabinet anti-theft system

The invention discloses an outdoor transformer cabinet anti-theft system, which comprises a detection module, an alarm module, an overhauling recording module and a mobile terminal. According to the invention, preliminary judgment is carried out through an infrared detector and a timer, an alarm host sends first-level alarm signals to an alarm server when a person is close to the periphery of equipment for a long time so as to remind the staff at a duty center to watch out; meanwhile, an image recognition device recognizes image information shot by a camera and judges whether the approaching person faces towards the equipment or not, and if so, the alarm host sends second-level alarm signals to the alarm server; and a door magnetic switch is used for detecting whether a door of the equipment is opened or not, and if the door is opened, the alarm host sends third-level alarm signals to the alarm server. The outdoor transformer cabinet anti-theft system combines the person approaching time, the person front facing direction and a door magnetic switch box, thereby increasing the judgment accuracy.
