The invention discloses an electricity larceny prevention apparatus for an electric power meter box. The apparatus includes a controller, an electricity larceny detection apparatus, a video monitoring apparatus, a communication module. The electricity larceny detection apparatus, the video monitoring apparatus, and the communication module are separately in electric connection with the controller. The electricity larceny detection apparatus is used for detecting the presence of electricity larceny behaviors and sending an electricity larceny signal to the controller. The controller, based on the received electricity larceny signal, controls the work of the video monitoring apparatus and sends an alarm signal through the communication module. The video monitoring apparatus is used for recording scenes surrounding the electric meter box and storing videos and images. According to the invention, the apparatus can report and record electricity larceny information in a rapid and accurate manner, which enables electricity inspecting workers who receive the information to arrive at the site in first time and conduct examination, correction, prevent electricity larceny, and provide effective evidence. The apparatus can effectively deter people who conduct larceny, avoid large amount of electricity loss, substantially increase inspecting workers' efficiency in electricity larceny prevention, and at the same time reduces zone area line loss rate and increase quality of power supply.
