4、 problems. The biggest characteristic of the power line carrier is not required to set up networks, as long as the wires, we can carry out data transfer. In line with the traditional security detection means, such as infrared, a variety of specialized sensing devices, to detect information stored in the storage unit, passed through the power line to the central control, security analysis, has reached the security effect. The design is first infrared detection unit by the NE555 and TK1838 microco
