摘要

Disclosed are a power line communication security camera, a power line communication decoder box, and a power line communication security system including the same, wherein cables for transmitting and receiving security data and supplying power are not exposed to the outside. The power line communication security camera according to the present invention is connected to a light bulb socket located at a high place in the home, and a socket connection part for transmitting and receiving a power signal including a data signal through an electric outlet of the light bulb socket, and photographing a certain portion of the home where the light bulb socket is installed. And an image data generator for generating and compressing the image data, and a signal combiner for combining the compressed image data with the power signal and transmitting the compressed image data to the socket connection unit. Because it connects directly to the light bulb socket located high in the home, the cable for data transmission and power supply is not exposed to the outside, so it is good in appearance, easy to install and low in cost. In addition, there is an advantage that it is not easy for children or intruders to unplug the cable because it is located high in the home.
