A power line communication (PLC) security system for achieving the above another technical problem is connected to a light bulb socket located high in a home, and the image data generated by photographing a certain portion of the home where the light bulb socket is installed is combined with a power signal to a power line. Transmitting security cameras; And a decoder box configured to receive a power signal combined with the image data through a power line, extract the image data from the power signal, and display the image data after processing.

Hereinafter, a power line communication security camera, a power line communication decoder box, and a power line communication security system including the same will be described in detail with reference to the accompanying drawings.

The system for the security of the home needs a device that can photograph the main place of the home by using a security camera, and to take a look at the captured image in one place. To this end, various types of security cameras are installed in the house. There is also a need for a decoder box that decodes and displays the video data sent from the security camera. The decoder box may be provided as a separate device, but the PC may also act as a decoder box.

1 is a diagram illustrating an external structure of a general security camera.

The general security camera 10 is installed in a portion of the home. The installed part is photographed to generate image data, and then compressed into various forms. Examples of compression may be various forms such as JPEG, MJPEG, MPEG, and the like. In order to transmit the compressed data to a decoder box, a connection cable 20 for data transmission such as BNC, UTP, telephone line, etc. is required. In addition, a power supply cable 15 is required for power supply of the security camera 10 itself. The power supply cable 15 is connected to the electrical outlet 30 to receive power.

As described above, the general security camera 10 has a cable 20 for data transmission and a cable 15 for power supply to the outside, which is not good to see, and children or intruders can easily pull out the cable. Have To prevent these cables from being exposed to the outside, additional equipment is required, which is expensive and difficult to install.

The cable 20 for data transmission can be removed by using power line communication (PLC). 2 is a diagram illustrating an external structure of a general power line communication (PLC) security camera.

When using power line communication (PLC), the data signal is transmitted using the cable 45 for power supply, thereby reducing one cable exposed to the outside. Nevertheless, there is a problem that the power supply cable 45 is exposed to the outside.

The electrical outlet 30 is generally located in the lower part of the house. On the other hand, the security camera 40 is generally installed in a high place in the home. Therefore, the length of the power supply cable 45 should be lengthened to supply power from the electrical outlet 30 to the security camera 40, and also transmit data.

Therefore, it is not good in appearance, children or intruders can easily pull out the cable, there is a problem that the cost is difficult and installation is difficult because a separate facility is required in order not to expose these cables to the outside.

In order to solve this problem, a security camera that does not expose the cable for transmitting and receiving security data and power supply is required. The present invention uses the electric light bulb socket (electric light bulb socket) located high in the home for this purpose.

3A and 3B illustrate embodiments of a connection between a power line communication security camera and a light bulb socket according to the present invention. 3A and 3B, the bulb sockets 71 and 72 are connected to the power line 50. Light bulb sockets 71 and 72 are provided with light bulbs 61 and 62.

The power line communication security camera 100 according to the present invention is connected to such bulb sockets 71 and 72. Since the structure directly connects to the light bulb sockets 71 and 72 located at a high place in the home, the cable for data transmission and power supply is not exposed to the outside. Therefore, the appearance looks good, can be installed at low cost, and can be easily installed. It is also located high in the house, making it difficult for children or intruders to unplug the cable. It is also an attractive system in areas where incandescent and halogen lamps are mainly used.

When the security camera 100 according to the present invention photographs a certain portion of the home to generate image data, the security camera 100 transmits the image data to a decoder box through a power line.

4 is a diagram illustrating an external structure of a power line communication decoder box according to an embodiment of the present invention.

The decoder box 200 according to the present invention requires a PLC power supply cable 205 for supplying power and transmitting data. The power supply cable 205 is connected to the electrical outlet 30 to supply power and to transmit and receive data.

The decoder box 200 according to the present invention processes the image data sent from the security camera 100 and sends it to the display 300. Display 300 shows this to the user.
